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.

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?
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.
Best regards
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
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!!!

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.
If you could list the chain of components required make this work, I would be very grateful.
I am a big fan of Baader products, I have found the quality and functionality to be exceptional.
Kind regards, David.
I also have a DSLR with the T2 adapter for Astro photography. Can you tell me specifically what additional adapters i will need to connect the flip mirror to the 2” opening on the Meade and to allow 2” eyepiece plus the DSLR?

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.
