It is clear here, and I plan on going out to view and photograph C/2022 E3 (ZTF) tonight in about 6 hours.
However, there is a problem. I happened to be checking stellariumweb for the RADEC, and the time to see it, and this comet is moving FAST. After adjusting the view to fit my true field of view, which is about 1.33 degrees, as every minute passed, the comet moved slightly.
This is all according to stellariumweb, but it’s a pretty good source for my astronomy hobby.
Anyway, I take pictures with my iPhone, using an app called NightCap. I take long exposures. If the comet is moving this fast, then I either really have to shorten my exposure times to about five seconds, or find another way to make sure that it doesn’t get fuzzy because the comet is moving.
My telescope can track DSOs and planets, but I don’t think it can track comets moving this fast. I could be wrong.
I do have a .5x focal reducer. If I reduce the FOV, will this help resolve the issue?
I realize that even then, the comet will be moving, but I bet it will move through the FOV slower if I had a focal reducer.
If this won’t work, I don’t know what to do.
Any idea on how I can get a picture without it getting fuzzy, because the comet is moving?

Thanks for getting back. I appreciate it. You’re absolutely right, it will be fuzzy. Shouldn’t make much of a difference.
Still, I think I will lower my exposure time.
Maybe I will also record a video of the comet moving out of the field of view.
I will make that decision tonight.
