asi 1600 mm c pro focal reducer distance

massimo1978

Good afternoon dear ZWO team.

I have one question and I hope you can support me. I need to know the exactly distance between the ASI1600 mm c pro and a focal reductor 0.8x . This is my set up:

Telescope : apocromatic 102 mm focal 714 mm

Focal reducer: skywatcher apo 0.8x for diameter 130 to 102 mm

Filter wheel: ZWO efw mini (5 position) .

No OAG

According with my calculation must be 53 mm.

Could someone of you kindly help me with this issue?

Thank you so much in advance

Sorry, the reducer is skyrover...I had wrong to write

Skyrover apo 0.8x 130 to 102mm

here is the way to connect it

1600+EFW+T2-T2+11mm T2 extender+16.5mm extender+reducer

6.5+20+2+11+16.5=56
