I have been scratching my head over this one for a while and I am a bit at a loss.
What is the object close between the red lines?
My setup is:
Skywatcher 200P quattro, 8" newtonian
Skywatcher EQ6R mount
ZWO ASI 294 camera with a ZWO filterwheel.
The attached picture is about 180 exposures of 30 seconds each in Ha (I cut out the interesting region)
This is part of the Butterly nebula close to Sadr. The black trapezium shaped object on the left is Barnard 347, a dark dust cloud.
The star right above this object is Gaia DR2 2067351863341990528 which is at
RA 20h 30m07.5s DEC +40°19'49.3"
Whereas the other stars are fairly round (still working on that) and crisp, this object is quite fuzzy.
It is also visible in https://stellarium-web.org/ , and it looks the same too. Same goes for the digitized sky survey images from World Wide.
And it is not in the Gaia database eventhough its neighbor and other stars that are apparently less bright than this one.
I also have a green channel image in which this object is a lot less bright which would indicate that this thing is pretty red.
Tonight I'll collect the red data and tomorrow the blue which would give a better idea of its color
