Hi there,
I'm having a lot of trouble getting the combination in the subject to a good focus on both primary and guide camera at once.
Can anyone recommend a precise spacing setup? I have all the spacers that came in the box with the ASI1600 (16.5m, 21.5m and a couple of adapters), together with a baader helical lens focuser.
I don't mind getting some more gear. I wasted the first clear night in about a month last night buggering around with this and I've got to solve it before the next!
Thanks in advance for any assistance here!
Nb. I'm using a Celestron c8 with a f6.3 focal reducer.
Jason
