M100 mystery object - any ideas?

[Neil_104]

So to find the various other objects scattered around my images, I usually trawl through numerous annotated Astrobin images until I fill in all the blanks. But there's a mystery object in my image of M100 that I've not been able to identify yet. It definitely looks non-stellar to me.

Does anyone know what this is at the end of the red arrow?? 🤔

It is galaxy.

In SIMBAD database it has following identifier:

SDSS J122218.25+154759.2

(from Sloan Digital Sky Survey)

It is about 320MLy away (z = 0.0233758)

Vlad beat me to it. I found the galaxy but didn’t know how to find the name.

Thank you Vlaiv and Stu for confirming it is in fact a galaxy 👍

Out of interest what are the best systems for finding really out there objects, irregular galaxies etc?

Pretty sure SIMBAD is the place to go. I couldn’t work out how to label up the galaxies nearby ones I knew the identity of though, obviously @vlaiv knows the secret 👍

I went to Aladin lite and found M100 and turned on labels - there is control to the right to select Catalogue

Then select target and get info:

I may need to use a smaller font for some of these more obscure objects 😂
