Product Questions

Does this T ring assembly fit the Baader 2 inch semi-apo filter?

Question by: Chris on Nov 12, 2016 11:14:05 PM | 1 Answer(s)

I need an adapter that will allow me to attach my Nikon 610 to my Celestron 8se that will take a 2" light pollution filter for prime focus astrophotography. I currently have a T-Ring and T-Adapter provided by Celestron, but it will not take 2" filters

Question by: Karl Kimmett on Dec 8, 2017 8:56:00 PM | 1 Answer(s)

I work with a Cambo x2 pro system mounted on my Canon 5ds.
Now i want to experiment with UV photography so i bought a SCHNEIDER-KREUZNACH COMPONON 60mm f/5.6 ENLARGER LENS which fits on my cambo x2 pro system. I'm not sure where to place the uv-filter, in front of my lens or is it better to place it in front of my body? For example: if i buy a Baader zero-tolerance protective Canon DSLR T-Ring T-2/M48 and 2" and put a 2" UV filter in there, does my EF mount cambo fit on the T-Ring or do i have to buy another adapter to do so? I'm a bit lost, can someone help me out? Thanks

Der Protective T-Ring hat eine Baulänge von 12mm und ist inclusive Filter (die optisch wirkasame Baulänge verlängert sich, wenn ein Filter in den Strahlengang eingebracht wird, abhängig von der Dicke des Filters) etwas länger als ein Standard T-Ring.
Wir kennen das Combo-System nicht - es ist schwer zu sagen, ob genug Platz vorhanden ist und dann noch der Fokus erreicht wird.

Komplett unvorhersagbar ist es, ob durch eine verkippte Linse irgendwelche störenden Reflexionen zwischen Filter und Objektiv auftreten. Zwischen Kamera und Filter ist das kein Problem, und wenn es Reflexe zum Objektiv gibt, sollten sie eigentlich zur Seite hinausgespiegelt werden - falls sie dort nicht auf irgendwelche reflektierenden Flächen im Objektiv treffen. Das müsste ma wirklich ausprobieren...

Einfacher wäre es wohl, wenn Sie den Filter vor das Objektiv setzen. Wenn es ein Filtergewinde hat, benötigen Sie dazu den
2" Filterhalter M48 auf SP54 für (D)SLR # 2408166
Dann steht Ihnen das SP54-Systemgewinde zur Verfügung, und Sie können mit den Hyperion DT-Ringen
https://www.baader-planetarium.com/de/zubehoer/adapter-foto-zubehoer/kameraadapter/dt-ringe.html
auf die gängigen Filtergewinde von Kameras (oder andere Step-Up/Down-Ringe) adaptieren.

Nachteil dieser Adaption: Der Filter sitzt vor dem Objektiv und kann bei Weitwinkel vignettieren. Dafür sind Reflexionen und Abstände kein Problem.

In another question you answered that the optical length of the Protective T-ring with filter chamber is actually 11,8mm and not the 12mm listed in the product specifications. Which value is correct?

Also, when using the Protective T-ring on a classic Canon EOS DSLR (44mm optical length) or with a new mirror-less Cannon R with their EF-EOS R adapter (20mm + 24mm optical length), this would put the total optical length at 55,8mm or 56mm.

Considering a Baader 2mm filter, we would then want to add 0,6mm to the total optical length to compensate for the extra focal length caused by refraction through the filter. This would then mean the proper optical length should be 55,6mm with a filter installed.

Based on the stated 11,8mm or 12mm optical length, that means the optical length would include an extra 0,2mm or 0,4mm in optical length respectively.

Will this difference in optical length have an impact? I ask because in another question I asked about the UFC system you suggested fine tuning spacers to get to exactly 55,6mm optical length when using the UFC system with a 2mm filter.

May I use the protective ring with a low profile cell mounted 2" filter like a baader 7nm h alpha filter inside the ring? (not on the nosepiece) or only naked 50.4mm filter are accepted inside?

I have this item can I use the nosepiece from it with your Nikon wide tring adapter? Do you have an IR cutoff filter that will screw into the nosepiece?

Any chance you will be making one of these adapters that will work with the Canon EOS M (EF-M Bayonet)? A few competitors of yours have EOS M to T-2 adapters but having one of these that would fit an EF-M Bayonet with a 2" filter in front that can also connect to your UFC system would be amazing.

Looking at the Protective T-Ring with filter chamber, it does not look like there is much room to grip and thread in a 2" threaded filter. Is there some tool available to insert and remove the filters like the pin type face wrench? If not how does someone insert and remove a 2" filter without touching the lens in such a small space?

Also, now that there are five different Canon EOS R camera models released, do you have any plans to make a version of this Protective T-ring with filter chamber that can directly connect to the Canon R Bayonet?

What is the thickness of this T-ring. Will work with the Skywatcher for reducer setup ? . Can it be screwed on to the Skywatcher 80ED dedicated ff/fr when a 3.5 mm thick 2" filter is screwed into the T---ring.

Baader Universal Filter Changer (UFC): The UFC camera-side adaptors (Part 4)

The UFC Camera Adaptors: In this latest blog on the Baader UFC System, we will look at the UFC camera-side adaptors. At present there are nine (9) different adaptors that will allow cameras to be attached to the (camera-side) of the UFC Base unit. These are shown in the image below. The image shows the type of fitment to the camera (e.g. T-2, FLI etc), the product code and also the optical path length (thickness) of the adaptor (which is important when using the UFC system with e.g. focal reducer where the camera sensor needs to be positioned at a particular distance from the reducer - we will cover this in a later post). All of the nine adaptors have the following common features: made of aluminium anodised matt-black have countersunk holes are attached to the UFC-base unit using 8 hex screws supplied with the adaptor for secure fitment (screws are flush fitting when fully tightened) The image below shows the camera side of the UFC Base on which all the UFC camera-side adaptors are fitted. Below is an image of a UFC camera adaptor showing the 8 countersunk holes in which the hex screws are inserted for...

Baader Universal Filter Changer (UFC): Simple photographic use example (Part 7)

Photographic Use Example: We've been asked a few times recently on how to set up the Baader UFC for use with a DSLR and a range of wide-field imaging refracting telescopes. So we thought we would write a short blog on some ways this can be done. Let us start from the telescope side first. All the enquiries we have had, the wide field refractors have 2" barrel focusers, so there is our starting point. The telescope side of the UFC Base (to which everything else in the UFC system is connected to) uses Baader's S70 dovetail adaptors to allow the UFC to fit to telescopes. Looking at the UFC main diagram above Baader do a Baader UFC S70 / 2" SC-thread (f) Telescope-Adapter (optical height: 1 mm) (#2459128, € 23,-) that allows 2"/SC male-thread accessories to be used. More about our UFC Telescope Adapters can be found in our blog: The UFC telescope-side adaptors. We offer our or our Baader 2" Safety Kerf nosepiece with 2" filter thread (#2408156, € 35,-) . The image below shows the latter 2" nosepiece attached to the UFC S70 2"/SC adaptor. Using one of these will allow the UFC to be attached to a...
