A couple nights ago, I got a pretty nice few hours on the Leo Triplet (M65, M66, and NGC3628). Right smack between them is a streak. I'm almost certain it's not a satellite, because it moves only a tiny bit over the course of the night, and I've checked SkySafari for satellites in that area. Also, the streak goes away during periods when I was doing the meridian flip, changing the battery, etc. I've checked the subs, and it definitely moves from sub to sub. So I'm pretty certain it's an asteroid/minor planet.
I checked the DE430 asteroids catalog in Pixinsight's AnnotateImage script, but it's not revealing anything there. I've tried a few other built-in PI catalogs and none of them have revealed what the object is. Are there other ready-made catalogs for PI that will identify what object this is? Barring ready-made PI catalogs, what's a good, medium-sized Vizier catalog that would do the trick?
