QHY600M/C PH Photographic Camera (Short BFL)

First there’s no doubt that 2-inch filters are large enough to cover the whole sensor area, but they’re not cheap enough for everyone. With a rough estimate, we think 36mm filter can be matched with scopes whose focal ratio are smaller than f/5 (f/4 worths a try, too). However, if your scope has a large focal ratio like f/2.8, we suggest you think carefully before using 36mm filters.

Note: Adapter Kits B1 is provided FOR FREE with each QHY268M model. B1,B2,B3,are suited for QHY268M; Adapter Kits D1 is provided FOR FREE with each QHY268C model. D1,D2,D3,are suited for QHY268C.

B1: Connecting MPCC that requires 55mm BFL and M48 interface to Camera with CFWL and OAG

Note:

1. If your MPCC requires a BFL different from 55mm, this adjustment can be made by selecting the appropriate spacer between the MPCC and the OAG. For example, an MPCC that requires 57.5mm can be used instead by adding a spacer ring or rings that add 2.5mm of BFL. to the diagram above.
2. If you don’t use an OAG, you can use a 10mm spacer adapter in the adapter kits to replace the original position of OAG.
3. Put OAG at the position next to the M48 Output to make both main cam and guiding cam focused.
