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

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, € 0,-) 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 Baader 2" Nosepiece with 2" filter thread (#2408155, € 35,-) 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 telescope with a 2" focuser.

Moving away from the telescope side, we next encounter the UFC Base itself to which the telescope side and camera side adaptors attach and the filter slider is inserted into. You can read more about the UFC Base in part 2 of our series of blogs The UFC Base.

For the filter slider either the 2" mounted, 2" unmounted or 50x50mm square versions can be used depending on what filters you currently have or may want to purchase. Using smaller filters (with one of the Aux holders) will likely cause vignetting depending on the size [age] of your camera's sensor). More information on the UFC sliders can be found in part 3 of our UFC blogs: The UFC Filter Slider

Next we get to the camera side of the UFC Base.

There are three possible "routes" for attaching a DSLR camera:

 

Baader Protective T-ring with S52 dovetail (and T-2, M48 and 2" nosepiece) attachments.

So lets put all of this together. In the image below we have an example setup based on what we have written above. From right to left: we have:

In a future blog we will look at other ways the UFC can be used for imaging purposes, including how to set the UFC up for use with focal reducers/field flatteners.

    Hi everybody,

    Are there any plans to extend the UFC range for adaptors and fittings for the Celestron RASA 14". I have a full set of fittings for the RASA 11" and if I upgrade to the 14" will the majority of the existing parts still be usable? (common sense says yes but you never know!)

    I can imagine the initial fitment to the OTA would be different but if there are plans to produce a compatible fitting could you clarify if the existing fittings would maintain compatibility?

    Thanks

    Best wishes
    Mark

      Hi Mark, the UFC-Adapter for the largest RASA (which is called "RASA 36cm" by Celestron themselves) is already available and can also be seen on the overview-graphic on this page. Here's a direct link:
      https://www.baader-planetarium.com/en/filters/universal-filter-changer/baader-ufc-s70-rasa-36-adapter-telescope-sided.html
      We confirm that all existing parts are still usable. The RASA 36 UFC-Adapter is just another "telescope-sided" UFC-Adapter which is connected via S70 dovetail to the UFC base like all the other telescope-sided UFC-Adapters.

    Hi - I have the a RASA36 and the UFC system. Should the UFC spacer adapters mount flush to the telescope side adapter? When I push the 15mm adapter onto the telescope side adapter there is a gap and it does not go on all the way and mount flush to the plate. Not sure if that is normal. I would think it might introduce tilt?

      According the geometry of the S70 connection it is normal that you can see a small gap. The surfaces which get in touch are inside the S70.

      Simply press the adapter down by hand and screw on each grub screw just until it touches. Then tighten them properly: always the opposite screws, similar you would do to fit a car tire.

    Dear Sir,
    I would be grateful for some advice on filter compatibility. I have the UFC system with 2x 2" filter sliders. I have tried to use my IDAS LPS-D2 filter but it is an extremely tight fit. The only way I can fully insert and then remove the filter slider with this filter in situ is to loosen the 8 sunk screws on the UFC camera adapter. Is this a known issue? I presumed the UFC was universal and would be compatible with most types of telescopes... cameras... and filters. It is after all called a Universal Filter Changer, not 'universal camera changer' or 'universal telescope changer'. Please advise. Many thanks, Jo

      Dear Mr. Bhattacharya,

      thank you very much for your inquiry and we are very sorry for the inconvenince. It is true that the UFC stands for Universal Filter Changer, however not all manufacturers use the same standard when producing filters and filtercells. Some of them have a very long thread on the filter cells, which causes the filters to be stuck inside the filter basis. If this is the case, with the filter slider, inside the packaging was also a thin ring, which can be mounted between the filter and the filter slider. This makes the filter sit a little bit higher, the thread won't come to the other side, and therefore succsessfuly avoid this issue.

      Please do not hesitate to contact us if you have any further questions or remarks.
