... Yes, I know this error and always zoom out when it happens. The issue, which I've mentioned in the past on this list and I never heard had been fixed, was...

... No idea, but it would always jump well off the image. ... Okay, then the cursor RA/Dec position is correct to the indicated X/Y coords? It would be easy...

As a matter of fact, I gave up (temporarily) on 'chasing' known asteroids as long as they are in the very crowded Milky Way star fields. I had no problem,...
Hi all, I'm just getting used to using astrometrica with SkyMorph. What would be the approximate magnitude beyond which its not considered worth looking for...
IMHO, in the best images, it's no worth trying to get deeper than 20.5 for code 644 and 19.5 for 566/608. I've written a summary that I use as a memory aide,...
