Hi everyone, I’m looking for some info… I’d like to try photographing a comet, specifically 3I/ATLAS, weather permitting. I don’t have any experience with this kind of imaging.
My setup is an RC10 f/8 with an ASI 294MM, an ASI 174MM OAG on a GM2000 QCI. I’m using 60-second exposures.
I tried last week using NINA and its Orbitals plugin, but something went wrong: I pointed the telescope at the comet and it was centered in the frame, but when I started guiding, the graph was completely messed up.
What am I doing wrong? Why isn’t the guiding working? Are the exposures too long? Should I set things up differently compared to classic deep-sky guiding? PHD2? Or should I just give up because of the long focal length?
Thanks.

It seems that you have to do something differently:
If you are using an OAG and have changed your fl, you need to tell PhD and run a guiding recalibration in the PhD tools.
Let us know how you get on.
