You want at least one Dec row of mapping points 1 degree above and 1 degree below your target. Each row should have at least five sky data points. You can define more points per arc for additional accuracy. (1 arc-degree apart would provide the most points).

Subject: Re: [ap-gto] Dec-Arc Tracking in APCC Pro v1.9 - an explainer please?
I usually set up and tear down every time I image, and I tend to do only one target in a night. What is the most
efficient way for me to do mapping and still get excellent results using dec arc tracking? Let's say that my target
has a declination of 53.15 degrees N. Should I do a single arc of maybe 10 or 20 points at declination 53 or would it
make more sense to do an arc at 50 and also one at 55? I think a lot of people are in the same situation, and we
could use some guidance. Thanks.
