I am looking for an OAG with a large prism to take advantage of the ASI174mm-mini sensor size. I plan on using this with the Starizona .65 FF/FR once i get it and will need 57mm backspace for train. The max length it can be is 29mm. It is difficult to find information on prism size. I just bought the Teleskop Service TSOAG27 to replace the ZWO OAG. I incorrectly interpreted the length of OAG for an M48. I thought it was 27mm but instead it is 33mm, putting me over where i need to be.
I am looking for a first-hand recommendation on what i can use. Thank you.
