Hallo folks, I will receive a SkyWatcher Esprit 100 ED refractor with the 0.75 x Riccardi reducer.
There are different statements on the internet about the backfocus.
The values differ from 78 mm to 80 mm.
Has someone made his / her own experience with the backfocus in this combination?
Thank you,
Christian
