Hi, dear friends in Astrobin. Recently I have tried to take deepsky pictures of Tadpole nebula, where on 16. of december I saw a moving star. She disappeared the next day. Can someone tell me, what it is?

Acquisitionsdetails are: Location Konstanz, Germany. Time 2024-12-16_21-19-30 to 2024-12-16_23-03. I made 5 min subs with Ha, OIII and SII, have to stop because of clouds.

Thanks in forward, You are wonderful community.

Hello, this is asteroid (15) Eunomia. I have used astrometry.net to solve your image and MPChecker https://cgi.minorplanetcenter.net/cgi-bin/checkmp.cgi You can also use Stellarium to confirm that, but I think you have to manually import Eunomia using the Solar System Editor.

How did you discover this in your images, Blink?

I also caught this a couple of weeks ago in that area, but it was closer to the spider/fly nebulae. The way I noticed it was in my starless image there was the telltale signature of a moving object. Check it out: https://www.astrobin.com/trnq3y/

Nice! I discovered it by accident during interactive local normalisation in WBPP/pixinsight processing. Who knows, how many times I missed something like this in the past? I wish You all a Mary X-mass/Weihnachten.
