Hi Folks
I’ve been using a Celestron 8” Edge HD on an Evolution mount for a year or so. Mostly visual, but I’m starting to dip into imaging.
I recently bought a wedge (I can’t afford an EQ mount atm). I use StarSense to align and then an all star polar alignment. And all seems to work fine, but I realise the polar deviation should be as close to 0 as practicable. So what numbers in degree terms would be considered ‘good as it gets’ given my mount and method? I need something to aim at
The pic is the deviation from one session.
Thanks.
What’s a useable polar alignment deviation?

Thanks very much 🙂
Pretty sure I can get both down to 0.1 deg or better with a bit of care when I do my ASPA. Just need another run of clear nights to practise 👍
