Default Very bright nebulous object in image.

I just opened up this image I took on December 17 at 9:30 PM. It is of the area around Beta Tauri. I just noticed a fuzzy object about a degree and a half north-west of Alnath that at first I thought was a star.

Nvm lol. I had just accidently painted a dot with the fuzzy brush tool on Photoshop. For a split second when I had just uploaded the image I was thinking: "Holy crud! It's gone! The government must be trying to hide something!" until common sense came back to me a moment later and I pressed "Undo brush tool" on photoshop. Lol, I'm not a UFO conspiracy theorist!
Here's the image anyway. I need to work on polar aligning and focusing. The telephoto lens I got as a gift is okay for astrophotograpy.

Nice picture. What was the exposure and focal length? My guess is several minutes and f=135mm, since the stellar magnitudes go deeper than +12. If the focal length is 135 mm, then the plate scale would be 10 arcsec per pixel. With a one minure exposure most satellites should move visibly with that plate scale. I stretch the picture in Photoshop and still don't see anything unusual other than some blue flair around beta Tau. How many pixels relative to beta Tau are you looking?

Take a picture of the same location next time you have the opportunity and see of the mystery object is still there.

Read my whole post. The "mystery object" doesn't exist. Also, the focal length was 300mm.
