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.
Photographing comet 3I/ATLAS: guiding issues with RC10 telescope setup
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.
Eclipse… and a comet?
So it looks like it may be possible to image the total eclipse AND comet 12P… In the same frame! (During totality) Now, since I’ve never taken a pic of either one, and there is no time for me to mess around to figure out exposures, I’d like to hear s...

Using a ZWO 2600MC Duo with a long focal length scope
I am considering buying a ZWO 2600MC Duo to use on our astronomy club Celestron edge C14 with the 0.7 reducer. This will mean I won't need a guide scope or off axis guider. Has anyone had experience using the Duo on a long focal length scope (C14...

I’m returning to DSO astrophotography after nearly eight years away, and needless to say, my PixInsight skills needed quite a bit of refreshing. I’m using the same setup as before, but I’ve switched to a Sony A7 IV DSLR for imaging because of its ver...

Blasted through the high clouds last night, interesting experiment... NGC 2064.
Last night I just went for it despite the unfavorable skies. I had cloud patterns that were semitransparent, so for one thing ASTAP was finicky to solve. Until I went back into my options in NINA and increased my exposure time for plate solving. The ...
