Any suggestions on how to do a 2 star alignment with an iOptron CEM70 and Stellarium combination? Thus far I've been using sharpcap for polar alignment. 

Tks in advance!

Hi Joe:

Why make a simple process more complex? Just use the alignment process in the Handset if you need to do any star alignment. I never do alignments since plate solving takes care of everything and is more accurate. Just set up ASTAP as your plate solver in Sharpcap and you'll never need to look back.....nor need to do a star alignment.

Cheers

Gary

If you are imaging, I'd suggest just PAing and then skip doing any star alignments and just use plate solving after each goto. I've been using a CEM120 and CEM60 for several years and have never done a 1, 2 or 3 star alignment. 

 

I use Astroart 8 (AA8) for mount and imaging train control. It has a built in plate solving engine, and plate solve assist for gotos:

 

1) start from home and goto first target and take a ~10 sec exposure; AA8 will plate solve it, determine the actual location of the image centre, then issue another goto which will typically place the image centre to within ~20 arc seconds of the target location.

 

2) take another ~10 sec exposure to confirm that target is centred.

Moving from EAA to Astronomy Software & Computers for a better fit.
