Could someone notice if that object close to the middle of the galaxy is a merger or just a normal part of the galaxy?

Hmmm...possibly a passing asteroid, it doesn't show the typical 3 colours of asteroid, but perhaps it is washed out by the glare of the galaxy, but it does show 3 parts, like an asteroid does in SDSS. Anybody else have any ideas?

PanSTARRS doesn't help, unless someone looks at the FITS files. I really must learn how to do them, but it is still 4th on my list of things to do.
another nearby galaxy doesn't show same blob

For me the PanSTARRS colour image does seem to help. I see a bright white galaxy bulge, and on the position of the object in SDSS clearly a more yellow perfect round object which is very likely a bright star.
Slightly better visible in the PanSTARRS g band cutout:
There are also two sources included in GAIA DR1, not clear to me if this means a binary or that the galaxy nucleus was included by misstake.

I see. Sorry for the delay, but work kept me busy and I just noticed how to find this again. Thanks for the help! With those images, it really sems like something on the foreground. At something I thought it could be a merger, but with some strange shape. And I didn't know about the "3 colours of asteroid[s]". Interesting!
