Hi guys, i’ve just processed my first image using my new edge 9.25 hd scope. Given that it is not a very eye catching image i don’t think many people are going to view it, but i would really like some input/opinions on my possible discovery. It is not a massive one so please dampen your expectations. Here is the link to the image….
And i will copy my image description here as it basically describes my request:
Hi guys. So this is my first processed image using my new Edge 9.25 telescope. I decided to have a scan around for something unlisted and i happened to find an obvious smudge on the DSS atlas that appeared nameless. I then checked a few other surveys and noticed the same smudge, also unnamed.
I then searched simbad and it came up with no results within several arc minutes of my co-ordinates. I decided this would be my target for my first processed image. After imaging the first night, i confirmed there was indeed an object there, aswell as 2 other objects that appeared un named. So it was looking promising.
I then remembered there is a new sky survey happening in the southern hemisphere so i checked that out. To my disappointment it appears that the dr4 catalogue has indeed listed this object and it says it has been observed and flagged 3 times. The object being DR4: Object 458631639 (SMSS J085157.57-614955.1) which is the small galaxy looking smudge in the center of my image.
The second object is also listed, DR4: Object 458621808 (SMSS J085143.49-615933.7) which is the very faint smudge to the left of the image just below center which also looks like a galaxy.
However, the final object i have found does not come up in the search and as far as i can tell is indeed undiscovered. It is the round orb that is towards the top of the image just left of center. The image i have created is an LRGB. And the object clearly shows up in the RGB wavelengths. I have also just ran a night of Oiii and Ha data and it appears to have faint signal in both but it is not obvious and i could assume it is just stray rgb light on my 3nm filters as the whole object shows up in Oiii. I am not skilled enough to incorporate the oiii etc into my image and i feel it could misrepresent it as it does appear to cover the hole object. I did notice in my rgb though that the top section appeared to have a blue fringe and when checking the sky survey data from dss and simbad, it also represents a blue shift towards one edge.
As a very novice astro photographer I feel like i have no more i can give towards this object or target. I am also unaware if i have optical issues in my image train and having this subject as my first deep dive with my set up i feel is over my head. I also feel like it is just another one of the thousands of galaxies that we see every image we take and it has no significance. But on the off chance someone with more knowledge than i would see this it would be cool to know if it indeed could be something more interesting like a small planetary nebula?
Given that whenever i annotate an image i always get ridiculously small galaxies that i can hardly see come up listed (there is actually one in the top right corner, PGC153209) i find it strange that these objects have not been found yet which is one of the reasons i am hoping it could be something else?
Best case scenario i’ve finally discovered something and can put my name to something cool. Worse case i learn a bit and use it to help advance my search for those illusive undiscovered gems.
Thanks, Clear skies
