Wide-T-Ring Nikon with D52 to T-2i

Yes, this works for the new version of the Herschel (Baader 2" Cool-Ceramic Safety Herschel Prism Mark II). Older models without the integrated rotating mechanism for the polarizing filter need Baader Adapter 2" (male) / T-2 (male) # 1508035 instead. Please note that the inner diameter of T-2-adapters is ca. 38mm, so there may be some vignetting with a full frame sensor. You will probably not notice it as the image of the sun ist still smaller. One meter of focal length results in a 1 cm large image of the sun, so you'd need about 4m of focal length to fill the frame. If you want to be sure, you should use Diamond Steeltrack® S58 to M48 BDS-Adapter # 2957204 and Reducing piece S52 / M48 # 2958552 instead of the S58/T-2-adapter #2957202. This will avoid any vignetting, and you can use the T-ring with 2" / S52 Nosepiece # 2958551 on any 2" focuser, if you later want to use it e.g. for Deep Sky photography without the Herschel wedge.

You can connect simply with a T-Ring https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/camera-adapters/t-rings-wide-and-classic.html in combination with a T-2 /2" adaptor https://www.baader-planetarium.com/en/baader-2%22-nosepiece-to-t-2--m48-(t-2-part-16).html which is the easiest and cheapest way.

Just see our PDF according digiscopy at page 4. In short the extender ring should be in length the diagonal of the sensor: https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/1211/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf
