Dave,
Good to hear about your journey...and your current situation.
Your rotating top looks like the "OctoDome" I used way back in the 1980's. Worked well for me.

Morten,
I'd assume that the minor (0.45%) improvement is due to the improved SNR with the stack.

Ok, by setting up one instance of AA7 to #1 camera (1000D), and opening a second instance of AA7 to #2 camera (450D) it is possible to control the cameras independently and have them both simultaneously exposing!!!!
Look forward to the first real trials....

This is an old thread..... I'm setting up two Canon DSLR's for spectroscopy. One, the 450D with a 85mm prime lens for wide field, and a 1000D on the ED80 for single star spectra. As mentioned previously you can use two instances of AA7 to control the cameras. I don't understand the camera selection ...

Patrick,
Which spreadsheet are you discussing?
I use the Miles (and Pickles) database in BASS Project for my spectrography.
Have you looked at:

Erik,
The focus routine already does this.
Check the Astroart Guide (F1) within Astroart and search on Focuser/ "Autofocus"

Thanks Fabio.
Your ongoing support to the amateur community is appreciated.
Stay safe.

I use UCAC4 but just noticed that UCAC5 was issued back in 2017.
It's not even mentioned on the UCAC website!

Has anyone tried it yet??

Glad to be able to help.

All's well that ends well.

I had similar problems... I received this sample script from one of the members (Iver): Maybe this will help. This is a script I run after a goto , it takes an image, solves it, syncs the scope to the image and then centers the target. raTar = Telescope.RA deTar = Telescope.DEC Camera.Binning(1) Cam...

Conrad/ Fabio,
There's an even easier way...
I use Sylvain's CORONO software.
