Hi All

 

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

 

Thanks!

Jan Jitze Krol

I do understand that there are tons of stars out there that have not yet been cataloged, but this one's appearance is what throws me off.

Plus it is big and bright enough to be calaloged I would think.

Here are some more pictures to highlight what I mean by 'appearance'

 

This is a crop of the main stacked image around the star in question.

And this is also visible in one of 200 the raw images:

Doesn't appear to be a star to me, else you would expect it to be a sharp bright circle as are the stars of similar size.

I will be curious as to the answer.

I am thinking that it is a small planetary. What is the number to Hubble control? smile.gif

Using the Aladin V11.0, it identified it as the planetary nebula Sd 1 and directed to SIMBAD https://simbad.u-str...ent=PN Sd 1

SIMBAD Coordinate Query is a good place to start.  It shows the AlladinLite view of the desired search radius over on the right side.
