Is this a distant ringed planetary nebula or an imaging artifact?
Hello everyone. I am imaging and processing Messier objects in APP from various sources including remote images I pay for. I search the Hubble Legacy Archive for suitable or interesting images to process. I would like your observation and opinion to answer my question in the topic title.
The image below is a standard wide field image of M36 to start the zoomed in path I will take.
The next image below is a Hubble image I downloaded of a much smaller portion of M36 taken in three wavelengths. There were a few hot pixels I wanted to clean up in certain areas one of which is the brightest star in the lower right of the image.
When I zoomed in to bit edit a few pixels I was surprised at what I initially thought was a distant, dim star just above the bright star that now looked like a ringed planetary nebula (see the image below). Many of you are much more expert at astrophotography processing than I so the question is is this a distant, faint nebula or an imaging artifact? Thanks in advance for any replies. Paul
@ah_astro Thanks for that info as I didn't know that site existed. I did not get a match on that site.
But I thought the Hubble Legacy Site should have the coordinates. I looked at the description of the image on the Hubble site and I did see the RA and Dec within a few minutes of the given coordinates of Messier 36. Now all I need is a way to look at those coordinates like on the Sloan Sky Survey or some such site.
Now I will ask if anyone knows of an all sky site where I can plug in my coordinates and retrieve information of the objects in that area of the sky? Thanks in advance.
