Exactly so.... on both counts.KathyNS wrote: ↑Sat Sep 11, 2021 11:18 pm The centering problem might be related to J2000 vs. Jnow. That is roughly the magnitude of offset you would expect from that. Coordinates from an atlas or database will be J2000. Actual coordinates in the sky are always Jnow. Coordinates from software could be either.
Nice cluster, regardless!

Yeah, I'll check J2000 vs Jnow to center and also see if I can nudge theLady Fraktor wrote: ↑Sun Sep 12, 2021 2:58 am Unfortunate they did not include the cascade.
Kemble 1/ NGC 1502 is one of my favorites
Addendum: I checked the coords I entered and I had used J2021.7 from SkySafari. The J2000 from

30 arcseconds is half of an arcminute, so 0.5 would be correct. I'm usingBen Cartwright SASS wrote: ↑Thu Sep 16, 2021 12:42 pm I have seen that often, especially with Canary One, the objects often are low in the fields.
