Baader Wide-T-Ring Canon R to connect Canon EOS R cameras on the Astro T-2 system and S52 dovetail
All Baader Wide-T-rings have an S52 dovetail in addition to the inserted T-2 ring. This allows the T-ring to be modified to an M48 female thread using the S52 / M48 adapter #2958552, or to use the S52 barrel #2958551 without the T-2 reduction. With the S52 / M68 adapter # 2458252, the Wide-T-Ring can be directly attached to an M68 male thread to securely fasten your camera to the widest possible aperture.
All Baader Wide T-rings can be directly adapted to an UFC (Universal Filter Changer) with the optional Baader UFC S52 dovetail camera-adapter (#2459119), in order to change different filter sizes directly in front of the camera sensor.
Furthermore, the illumination of the camera chips improved significantly, mainly because of the larger clear aperture.
On the camera side: Canon R Bayonet
Telescope side: S52 dovetail clamp incl. S52/T-2 internal thread with 0.75mm pitch

I have a canon rp with the baader m48 t ring on and an apertura 72ed with the field flattener and an optolong cls 2" filter on the flattener. How much backfocus do I need and what spacers and adapters should I get?

I would like to use this Canon R Wide T-Ring and the UFC system as shown in the product image with the telescope. I want to use it to attach a Canon EOS R to my telescope's field flattener which has 55 mm of back focus and a male T-2 connector.

I have Canon EOS R5 full frame mirrorless camera (RF-mount’s flange focal distance is 20mm) and I am going to buy Celestron Nexstar 8SE Telescope.
My goal is to get good photographs from planets, moon and maybe deep sky objects too. I know, that I need high quality optical elements between the telescope and the camera to achieve the goal.
I am going to buy Baader 2" BBHS ® Prism Star Diagonal Prism with 2" ClickLock Clamp, Baader Hyperion Universal Zoom Mark IV, 8-24 mm eyepiece (1¼" / 2"), 9 mm and 17.5 mm Morpheus® 76° widefield eyepiece. VIP 2x modular barlow lens is also in my list.
What kind of adapters, extensiontubes and other finetuning products do I need to attach my camera to eyepieces? I think I need a new Baader Wide-T-Ring Canon R but what else to get good astrophotographs?

With a modern camera with small pixels and a Schmidt-Cassegrain at f/10, a barlow lens like the 2x VIP is usually sufficient, especially if you boost it with some T-2-extensions as described in this PDF: https://www.baader-planetarium.com/en/downloads/dl/file/id/240/product/1062/calculating_different_magnifications_with_the_vip_barlow.pdf

This way, you can match the f/ratio to the resolution of your camera.

We have described the adaptation of a camera to an eyepiece in this PDF: https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/1210/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf
This will result in much higher magnifications than a barlow lens, so with a f/10-telescope, the barlow lens is usually the better choice (with modern cameras). On page 5 of this PDF, you can find a formula to calculate the best magnification depending on the pixel size of your camera.

For photographing the planets, we recommend a dedicated video module like the QHY planetary cameras https://www.baader-planetarium.com/en/cameras/qhyccd-kameras/planetary-and-guiding-cameras.html or the Celestron NexImage. The large sensor of a DSLR is not helpful when taking images of the planets.

It is fine for taking images of the complete moon or the (with an appropriate solar filter in front of the telescope) the sun. To attach your camera directly, you can use Baader SC / HD Ultra Short T-Adaptor, 7mm optical length # 2958500B (which limits you to the smaller diameter of the T-2-system) or you upgrade your telescope with a 2" eyepiece clamp like Baader 2" ClickLock SC/HD (2") clamp (C5" - C9¼") #2956220 and couple the wide T-ring with 2" / S52 Nosepiece # 2958551.

For Deep-Sky-photography, you should use an equatorial mount like an AVX - you could also purchase the wedge for the NexStar SE, but the AVX is a much better solution if you want to take photos. It is much sturdier and not that much more expensive than a SE plus wedge.

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 , € 25) 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 , € 43) . 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...
