I cannot get the image in the eyepiece to center. I'm using the Baader Focusing Eyepiece holder. I have moved the adjustable T2 ring to its limit, but the image when centered in the camera is at the edge of the field of the eyepiece. Ideas?

I have a Skywatcher 150/750 PDS with a back-focus of 86mm. This Newtonian reflector is optimized gor astrophotography. Flip mirrors are generally not compatible with reflectors. However, in this case, given the optical path of the Baader flip mirror, would it be possible to use it on my scope? If so, how? Thank you.

Can you please tell me what thread adapter or other adapter I would need to go from the back of the Baader Flip Mirror II, which I think is M48, but please correct me if I am wrong, to a Baader 2" ClickLock for Celestron & Meade SCT?

The reason I am asking is because I purchased several of your products a few days ago. A couple of them being a Baader 2" ClickLock Adapter for 3.25" SCT's and just in case that didn't work I also got the Baader 2" ClickLock for Celestron & Meade. Well, the Baader 2" x 3.25" worked flawlessly. Now I'm left with an expensive Baader 2" ClickLock for Celestron & Meade SCT.

So, what I'd like to do is mount the Baader 2" ClickLock for Celestron & Meade SCT on to the back of the Baader Flip Mirror II to make it easier to mount my DSLR to the back of the flip mirror, but I am unsure of the specific thread adapter/s I would need to make it work. So, I need to go from the back of the Baader Flip Mirror II to the Baader 2" ClickLock for Celestron & Meade SCT.

Can you please help me figure out what part or parts I will need to make it work? Do you have a thread adapter to make this work and if you do can you please provide me with the Baader part number/s?

Any help you can offer would be very much appreciated.

Thank you.

I would like to use your "flip mirror" as a ligth sources selector with my leitz microscope (LED cool ligth or halogen one); to do this I would like to replace the adapter rings with Leitz ones on two sides of the unit; the third one will be used for straigth connection to microscope inlet (by a locked coupling ring).
Do you think it is feasible? may you send me a tech drawing with ring holes on the three sides?
I thank you in advance for your kind answer.

I've just ordered a Celestron 9.25 XLT telescope for planetary viewing and astrophotography. I think adding a Baader Flip Mirror for my imaging train would be quite convenient. With the flip mirror I will probably only use an eyepiece on one end and a Barlow, UV/IR cut filter, an ADC and a planetary camera on the other end. All this equipment is 1.25 inch. Will I need extra accessories, like a click-lock or specific kinds of threads, to attach everything to the scope and mirror? If so, what kinds would work? Thank you.

What accessories are recommended for achieving 133mm backfocus for Celestron Edge HD 8 with a DSLR (with native 55 mm backfocus when used with a t-ring)?

Without any adapters, 55mm flip mirror + 55mm backfocus of a DSLR (with t-ring) leaves 23 mm of optical length left. #2958500B for the SCT connection gives me 7mm + 2mm for the T2 adapter shipped with the mirror. I then have 14mm left to connect the DSLR t-ring to the mirror somehow, correct?

Then if I were to use 2458100 as a focusing eyepiece holder, I'd just need to find T2 extension tubes to achieve the same optical distance to the eyepiece flange, correct?

I already own a Celestron C6 SC XLT with a much appreciated Hyperion Mark IV zoom. I would like to replace the stock diagonal with a Baader FlipMirror II.

The idea would be to

- permanently connect the FlipMirror II to the telescope using the "Baader SCT T Adaptor Ultra Short 10mm Optical Length"
The space available to rotate the flipmirror for screwing it in seems not enough on the C6, but I have seen that it is possible to screw it in without the telescope focus knob getting in the way if the rubber jacket of the knob is temporarily removed.
- connect a DSLR to the straight FlipMirror output (I already have a low profile Canon T2 adapter)
- use my Hyperion Zoom MkIV on the angled top output, either directly screwed in or through a baader 2" clicklock since I might use other Eyepieces

Besides flipmirror, SCT adapter and clicklock what other components do I need to have for having the DSLR and the eyepieces at the same focal distance from the scope?

Thanks for your advice

Hello Baader, I love your products because they are of excellent quality and workmanship. So thank you for that.
Anyway, I have your Baader FlipMirror ll #2458055 and I was hoping you had an adapter that went from the threads on the top opening to a 2" twistlock? Would you happen to have this item and if so could you please tell me the item number so I can order it. I already have several items in my shopping cart, one of them being the Off Axis Guider for Baader FlipMirror II (BFM-OAG)
# 2956951 for the small bottom port, and I would like to get them all at one time if possible.

So, thank you for your outstand sales and service, let alone your excellent products. I will definately be a lifelong customer!!!

Hello, I have a question about the Baader Flip Mirrors for use on SCTs (Celestron 8SE to be exact). I'm trying to be certain as to which adapters I would need to attach it to the scope, use an eyepiece and attach a ZWO ASI 224MC camera.

To connect to the 8SE I believe I need this - Baader Ultra-Short (10mm) SCT Female to T2 Male T-Adapter # SCT-T 2958500B. Correct?

What about a ZWO ASI 224MC Camera? Would I have everything I need or would I need some extension tubes?

For an eyepiece holder that focuses looks like I need something like this - Baader 1.25"/T-2 Eyepiece Holder with Helical Microfocuser # EYEHOLD-2 2458125. Correct?

I don't know if I'll need any T-2 variable / fixed extension tubes. Here's I'm completely clueless. Most likely I would use an eyepiece with crosshairs (SvBony's 20mm or Orion's 12mm).

Thanks for the help. I plan to order a flip vendor from Agena Astro as soon as I know all the adapters I would need.

Recently I bought BFM-OAG (off-axis guider for BFM). I immediately realized that if I want to find relatively bright guide star, I need to rotate BFM around the optical axis. I can loosen the T-adaptor and rotate the whole assembly (BFM, eyepiece, OAG, camera), which is not convenient. Do you have any accessory/adapter which allows to rotate only BFM+OAG but not the camera?

In order to use the OAG port at the base of the flip mirror, the prism can only go so high before it will hit the mirror when ‘down’. If your connection to the telescope relied on a 1.25” nosepiece rather than a 2” / T2 /M48 connection, would the light ever reach the prism as it would be too low to pick up any light?

Baader FlipMirror II Star Diagonal

Various ports – variable work

Telescope auxillary instruments cover a wide range of interests, from a sole eyepiece, via camera use, to high end spectroscopy. Unfortunately every telescope just features one exit port. This causes relentless manual exchange of parts in the dark, causing huge time loss, wear on the parts - and "nerves". And whenever you start controlling your telescope remotely - the single port becomes a painful reality.

Improving workflow, especially during astrophotography is the goal set out for the BFM II. This is not just a simple flip mirror but much more, as there are three ports to be put into action. The BFM II also enables the precise adjustment of all light paths.

BFM II makes your single telescope port variable – to suit your various interests.

The FlipMirror II Star Diagonal allows a variety of permanent adaptations to your telescope 1 . Use the rotary knob 2 to switch between the rear port 3 and the top port 4; you can use an optional toothed belt to operate it with a motor (not included). An autoguider or a calibration lamp can be connected to the bottom port 5.

Baader-FlipMirror II Star Diagonal (BFM II) offers you three ports:

  • Straight-through (S52, M48 and T-2 on both sides) for full-frame camera, spectrograph, or other instruments
  • Adjustable T-2 thread on top for eyepiece clamps, video modules (up to 32 mm image circle) or even a binoviewer
  • Bottom flange for the optional Off Axis Guider for Baader FlipMirror II (BFM-OAG) (#2956951 , € 122,-) or for an optional calibration lamp for quick calibration of spectra without removing the spectrograph.

The rotatable M48 connection rings are made of hardened, stainless steel on front and rear. They are adapted backlash-free to the BFM housing, so that they can be fixed in the optimum position to rotate any accessory around the optical axis. The BFM II is compatible with a large number of adapters from the Baader Astro T-2 system, the M48 system and the UFC system (Universal Filter Changer)

General Function of the FlipMirror II Star Diagonal

The heart of the BFM II is a precise surface-mirrored flip mirror with multi-layer Al coating, which can be used as any regular gigh-end star diagonal for visual observations and for high-resolution images with cameras with small pixels. In addition, the BFM II lets you switch between a straight light path (Position A) for a camera or other measuring instruments and an angled light path (Position B), e.g. for an eyepiece. The following figure shows how it works. In addition, a calibration lamp for spectrographs or an Off-Axis-Guider pickoff-prism (that is not affected by the mirror position) can be connected at the AUX-port on the bottom. The back of the flip mirror is also Al coated and masked to direct the light of an optional calibration lamp onto the slit of a spectrograph.

Scope of Delivery of the Baader FlipMirror II Star Diagonal:

  • Baader FlipMirror II Star Diagonal – with fine-optically polished, movable mirror
  • Laterally adjustable T-2a top ring
  • 2x M48i / S52 Dovetail ring made of hardened stainless steel # 2958552
  • Reducing ring M48a / T-2i # 2958553
  • Reducing ring M48a / T-2a # 2958554
  • Inverter ring M48a / M48a # 2958555
  • Pin type face wrench for M48 / T-2 and M4 counter nuts
  • 3 mm screwdriver for M 4 brass adjustment screws
  • 4x hex keys (2.5 / 2.0 / 1.5 / 1.3 mm). The 2.0 mm wrench has a ball head to reach screws even when accessories are mounted by holding the wrench at an angle.
  • Bottom flange (laterally adjustable 1mm) for off-axis guide or calibration lamp for spectroscopy
  • Dust cap for bottom flange
  • 2 x M48 dust caps
  • T-2 dust cap

STRAY LIGHT PROBLEMS ON CELESTRON EDGEHD 9.25 TELESCOPE AND APS-C CAMERA - REPLY
I could not add pictures to the intended reply. So I created a new review with a 5 star rating due to the applied improvement.


The reflections on the back of the folding mirror are a serious problem with larger Celestron SC telescopes.

I tested the following solutions to cover the back of the mirror:
1.
Black printed paper or black photo book paper. This doesn't work very well. Light rays that run almost parallel to the tube surface are still well reflected. First photo.
2.
Good optical black paint on the paper back.
This helps a lot, but the reflections are still there. Second photo.
3.
Optical black painted sandpaper.
This works well. Third photo.

The cover plate is 30 mm wide and 31 mm long. Additional folded edges, 3mm 45 degrees at the front and 4mm 90 degrees at the rear, increase rigidity, help positioning and prevent reflections on the leading edge.
With 2 strips of double-sided adhesive tape of 2-3mm wide, this cover plate can be fixed without damaging the original rear mirror.
Prior to assembly I made the cap from No. 60 sandpaper, which was then painted black with slightly diluted Sennelier Mars Black No. 759 Matt (60ml per sachet, available cheaply from art supply stores).
See fourth photo.
  • The problem of reflections on the rear of the mirror can be solved
  • Nothing after the applied improvement

Thank you very much for those tests and helpful improvements. For those who want to use the BFM II in such constellations like you do, this certainly improves the overall functionality. It's good to see that the BFM II can be upgraded so easy also for this usage

Stray light problems on Celestron EdgeHD 9.25 telescope and APS-C camera
This is a very nice product having a lot of options!
I'm using it with a Celestron EdgeHD 9.25 telescope.
The light path to the camera consists of:
- The Celestron telescope adapter 3.29” to 2" male (d=12,7mm)
- The Baader T Adapter for SC 2" to M42 male (d=15,5mm)
- The Baader flip mirror (d=59mm)
- A camera T-2 360° rotator (d=14mm)
- A T-Ring adapter for Canon EOS (d=10mm)
- A Canon EOS 77D camera with APS-C sensor (d=44mm)
The optical path is now 155mm while the target value is 146mm.

Unfortunately I found some flip mirror issues:
1. On the mask at the back of the mirror there is some harmless light grey dirt. It should not be there. See picture.
2. The dimensions of the mirror are such that 36x24mm is reflected. That's quit small to cover the inner 38mm of the 42mm tube system.
The original Celestron star mirror has no restrictions caused by the mirror size. Luckily the limited Baader mirror size is at the upper port for visual observations. That does not harm to much.
3. In the up position the mirror is quite low in the light path. I expect extra vignetting in the case of a full frame sensor.
4. Most anodized parts are highly reflective in the near IR. So for IR applications some painting needs to be done.
5. Stray light from the rear mirror. This needs to be solved. See pictures.

What is the best way to solve the stray light problem?
- Another mirror with no reflecting part at the rear?
- Adding some black rear cover?
- Optical black paint?
- Some kind of a mask in front at the input port?
- Adding a screw to tilt the mirror from the zero position?

Please your advice on the stray light issue.
  • Nice mechanical building quality and a lot of options
  • The stray light problem and a quite (almost to) small mirror

Thanks for your review as well as your criticism. Please note the following however:
The Baader FlipMirror II was designed as an entry level Flip Mirror solution for guiding and visual inspection in mind. While it can serve as a diagonal, it still has limitations compared to a real Diagonals. The mirror in the BFM II already has the largest known size for a flip mirror in the M42/M48 area (at least to our knowledge). Larger mirrors also means larger backfokus which is usually not wanted.

We are aware that the BFM II Design leaves some wishes for more functionality and improvements. Given the price of the product we can not implement them all in the BFM II. But we will keep them in mind for future products which could be larger and likely more expensive and therefore leave some room to implement a lot of the things you wished for improvement.

Vario Finder und FlipMirror II
Die RASA Astrographen sind ausschließlich für die Fotografie designed. Für die visuellen Anwendungen wie Objektpositionierung, Nachführung oder Polausrichtung des RASAs auf einer Montierung wurde der Baader Variofinder (61/250mm) sowie der FlipMirror II eingesetzt. Auf diese Art kann zwischen der Nachführkamera und einem Okular (hier: Fadenkreutzokular) gewechselt werden.
Ich hatte die Gelegenheit diese Art der Nachführung (Sucher+FlipMirror) mit verschiedenen Teleskopen auszuprobieren und sie erwies sich als zuverlässig.
  • Vario: leicht, kompakt, sehr gutes Fadenkreutzokular. FlipMirror: breite Auswahl an Adaptationmöglichkeiten mit anderen Produkten. Auslieferung als Set (Vario + FlipMirror+ Fadenkreutz + Nachführkamera mit Drehfokussierung) wäre interessant.
  • Die im Auslieferungszustand eingebauten Ringe sitzen zu fest. Der Stirnlochschlüssel verbiegt wenn man zu fest angezogene Ringe lösen will.

So muss FlippMirror sein
Am Anfang (aus der Ferne) machte ich mir Gedanken über die Orthogonalität des Klappspiegels, dessen Fassung, Drehlagerung und vorallem über die Verwindungssteifheit des gesamten Gehäuses. Denn daran sollten eine SBIG STF-8300M, eine kleine Guidingcam Alccd-QHY 5III 174 und ein Okular platz finden. Ein beachtliches Gewicht für so einen kleinen "Würfel". Meine Bedenken haben sich nach einigen Nächten praktischen Einsatzes in Luft aufgelöst. Bis auf eine kleine Sache, was die Adaption des  Off Axis Guider für Baader FlipMirror II (BFM-OAG)
# 2956951 angeht. Hier hatte ich anfänglich zu vorsichtig die beiden Madenschrauben, die den Guiderport am Flippmirror arretieren, festgeschraubt. Nach kurzer Zeit bemerkte ich ein Verkippen der Guidingkamera bzw. des ganzen Off Axis Guiders. Hier darf man ruhig die beiden Schrauben sehr straff anziehen. Sonst wird der Guider nicht fest genug sitzen! Hier wäre m. E. eine Gewindelösung der Schnittstelle angebrachter.
Funktionell muss ich in meinem Fall keine Abstriche machen!
Der Flipp Mirror ist ab Werk bereits sehr gut justiert, sodass im Normalfall keine Nachjustierung nötig ist. Hier liegen zwischen dem Baader Flip Mirror und anderen Produkten (auch einfachen Zenitspiegel) Welten und ich habe schon einige gekauft und wieder verkauft!
In Summe kann ich den Flipp Mirror nur empfehlen!
  • Stabilität und Justierung ab Werk
  • Aufnahme des Off Ais Guider sollte m. E. per Einschraubung erfolgen.
    Nicht als Stecklösung, fixiert mit Madenschrauben.

Vielen Dank für Ihre sehr positive Bewertung. Wir verstehen Ihren Einwand, dass ein Gewinde grundsätzlich für eine festere Verbindung sorgen würde. Allerdings ist dies nicht ganz trivial, denn das Gewinde müsste ja dann noch drehbar sein, da man den Anschlagpunkt (Endpunkt) des Gewindes nicht fest definieren kann und somit der Off-Axis Guider evtl. nicht Richtung Teleskop zeigen könnte. Die Stecklösung ist daher aus unserer Sicht die universellere Lösung - und nach Anfangsschwierigkeiten aufgrund zu lockerer Schrauben scheint es für Sie ja auch zu funktionieren.

Gutes Produkt, Guter Support
Einfach zu benutzen, sauber und wertig verarbeitet. Wer eine DSLR oder Systemkamera zusätzlich zur live Beobachtung ans Teleskop anschliessen will, wird den Flip Mirror nicht mehr missen wollen, es muss nicht jedemal der komplette "Image Train" umgebaut werden, wenn man zwischen Beobachtung und Fotografie wechseln will.
Die Konfiguration der benötigten Adapter ist nicht unbedingt einfach, mit der Hilfe des hervorragenden Supports bei Baader Planetarium klappt das aber sehr gut.

Celestron 8" EdgeHD auf AVX Montierung; Baader Flip Mirror II; Baader Universal Filter Changer (UFC); Canon EOS-M; 40mm Celestron Plössl Okular; diverse Adapter und Verlängerungen...

    • @Wolfgang What is this element between the Baader Flip Mirror and the Celestron EdgeHD 8" telescope? I am trying to find a way to connect with a reducer that is short and allows for possible rotation to maintain a comfortable viewing angle. In the photo it looks like what I'm looking for, it's short and screws into the Celestron thread.Was ist dieses Element zwischen dem Baader Flip Mirror und dem Celestron EdgeHD 8"-Teleskop? Ich versuche eine Möglichkeit zu finden, eine Verbindung mit einem Reduzierstück herzustellen, das kurz ist und eine mögliche Drehung ermöglicht, um einen angenehmen Betrachtungswinkel aufrechtzuerhalten. Auf dem Foto sieht es so aus Was ich suche, ist kurz und lässt sich in das Celestron-Gewinde einschrauben.

Definitiv sein Geld wert!
Dies ist definitiv der besten Flip Mirror den ich bis jetzt hatte. Die sehr gute Verarbeitung und Haptik fühlte sich gleich richtig an. Der Spiegel schaltet dank federnder Lagerung satt aber gedämpft um. Auch die Möglichkeit den Anschlag des Spiegels zu verstellen steigert dessen Wert nochmal im Bezug auf die Ausrichtung des Gesichtsfeldes. Durch die umfangreichen Adapter sollte einem Test nach Erhalten nichts im Weg stehen. Nach ein paar Minuten war er bei mir einsatzbereit. Die optische Länge ist bei meinem NP101 immer sehr knapp, aber ich bin bis auf den mm genau in den Fokus gekommen und konnte noch eine Schnellkupplung zur Bildfeldrotation einbauen. Die optische Qualität ist auch sehr gut, so konnte ich die Objektausrichtung prüfen, bevor ich sie fotografierte. Einen Unterschied zu meinem Everbrite konnte ich jetzt nicht feststellen. Die Spiegelfläche deckte das Gesichtsfeld meines Delos 12 mm voll ab. In Zukunft werde ich auch noch das Prisma für OAG testen. Bin schon gespannt. Ich denke, dass das meine letzte Investition in diesen Bereich war!
  • die Sehr hochwertige Verarbeitung und die vielseitigen Verwendungsmöglichkeiten
  • Der Stirnlochschlüssel hätte ein wenig stabiler sein können! Bereits beim ersten mal leicht verbogen!

Die richtige Kaufentscheidung
Anfangs hatte ich doch einige Schwierigkeiten die Adapterringe richtig zuzuordnen, aber mit Hilfe des Baader Teams habe ich dann meine Konfiguration wie geplant ausführen können.
Leider habe ich noch keine Möglichkeit gehabt den BFM2 in der Praxis auszuprobieren.
Auf jeden Fall habe ich da ein wertvolles Zubehör zu meinem Equipment erhalten. Das kann ich mit Gewissheit sagen da ich vorher ein FM eines anderen Hersteller verwendet habe.
  • Die qualitative Verarbeitung
  • Bis jetzt noch nichts
