Aladin is a good viewer.

I think this is a cosmic ray hit. It’s gone on other surveys.

Thank you. I am interested in posting objects in another thread using Aladdin lite.

A third telescope reflection. All of these seem to be close to bright stars. There are some more of these in the survey
I see a lot of these "smears’ or instrumentation reflection. Different colors too.
Horsehead Nebula (evolved a lot since it was first discovered) I don’t see the “horse head” Maybe its the instrumentation’s resolution. I have only the siMbad coord. I don’t see at the “8000” post from last year.
Bright Star or artifact? The center may be instrumental overload or reflection( I have seen different position/colors elsewhere). My imagination says I see something of a star’s corona.
