That's it; I'm throwing in the towel..!
After countless of attempt - I have not once succeeded in a decent frame... Unfortunately, my evening hasn't been long, the last couple of years. With small children that have to get to bed, I have had max 2-3 hours before going to bed myself, which have consisted of setting up all the equipment and cables, trying to polar align (but never really successfully), and lately to many software bugs/errors - all ending in nothing and me having to take everything down again.
Mostly I find out what the problem is and try to avoid/fix it next time, then something new goes wrong, or the same reappears ageing...
I would love to add some equipment to my setup which I believe could enable a more straightforward setup, go to upgrade, guide camera, etc., but there will probably go a couple of years before the budget allows for that.
Hopefully, one day, I will try again, but for now, I done...
