Chasing Polar Alignment
I finally cracked it tonight and am able to image out to 4 minutes with no trailing, though I'm taking it easy and limiting myself to 2 minutes..
Strangely, polar alignment was getting worse the longer I worked on it, despite getting as accurate as possible. I went from around 40 arc seconds up to about a minute 30... It then occurred me to park the scope, turn it off and start again. The alignment, first time around, was 23 and 24 arc seconds. I ran another alignment on different stars to be sure and the same.
I've never heard of it before, has anyone else?
