I just ordered the new Canon Ra. I would like to find an M48 ring to screw my corrector on.
Do you have a compatible ring?
Is this ring compatible?

Thank you very much for your reply.

You have a lot of documentation on how using this with an eyepiece but none that I can found if I want to directly connect my camera to the eyepiece holder without going through the eyepiece itself.

* In this case is there a minimal extension distance to respect between the camera and the (empty) eyepiece holder? (with eyepiece for full frame hybrid you say 95mm)
* What is the impact of the extension distance on the magnification? (with eyepiece equivalent focal length is Feq=Ftel*(d/Feye-1)

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?

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.

The illumination of the camera chips improved significantly, mainly because of the larger clear aperture.

Gute Qualität
Macht einen sehr guten Eindruck, sieht wertig und solide aus. Passt sehr gut ans EOS R Bajonett, kein Spiel und sitzt satt.
Aber : Warum ist dieser Ring nur 8,3mm lang ?
Auflagemaß der Canon R sind 20mm + 8,3mm T-Ring + 25mm 2" / S52 Steckhülse ergibt 53,3mm Abstand. Gefordert ist normalerweise ein Abstand von 55mm vom M48 Gewinde eines Korrektors bis zum Chip.
Dafür muss ich leider ein Stern abziehen.
Danke für Ihre Bewertung.
Generell ist zu sagen, dass wir die Wide-T-Ringe alle so kurzbauend wie irgend möglich gemacht haben, da es immer weniger Systeme gibt die auf dem alten 55 mm Standard aufbauen. Der 55 mm Abstand stammt aus der Zeit der Tamron T-2 Objektive, die damit und mit den passenden T-Ringen universell an alle Kameraformate adaptierbar waren. Heutzutage ist das Format nicht mehr zeitgemäß weil es zu lange aufbaut, T-2 Objektive haben die wenigsten noch. In aller Regel werden sogar noch kürzere Adaptionen gefragt. Daher haben wir die T-Ringe so weit und kurz wie möglich gemacht, damit danach alle weiteren Möglichkeiten, betreffend einer Adaption, offen bleiben. Insbesonders z.B. in Kombination mit unseren diversen neuen M48 Zwischenringen und (Fein)Abstimmringen.
