Also I notice you forgot the step where you slaughter the goat and spread the entrails around the telescope. Don't make the mistake of using a rabbit, the gods don't like that one bit.

Sadly, only sheep were available nearby, so I had to do without
I think my guidecam exposures were set to 200ms. What is a good value to try?

So I switched to an OAG. It works a dream, now I can readily do 20+min subs with round stars. And it would suit your QHY5L-II (which is very sensitive, and has the same chip as my ASI120MM). |
Yeah I was trying to avoid the spend as long as possible, so I may just have to stick with the wide field stuff for now
I've added one of the "guided" images I took that evening, although I'm not sure if it gives any more clues
