Re: Tracking Graph Diagnosos

M Hambrick

I was imaging NGC 4565 which was almost directly overhead when I made this graph. I am at 30 Deg latitude, so it was also pretty close to the Zenith.

Is a 1 arc sec per minute drift high enough that I should check out my RAPAS ?

I am always guiding when I take my images. In this case 10 minute subs. With guiding turned on, the guide star will typically stay within + 1 arc second.
