Distant clusters around M82

[drjolo]

I always like to look for distant worlds in the sky, and when I stacked 400 minutes of luminance captured for my new project, I found some faint flocks at the frame edges. It turned out to be distant galaxy clusters located 2600 and 3000 millions light years away: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%408444694&Name=XMMXCS J0953.7%2B6947  and  http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%4010548357&Name=SDSS J095324.38%2B693648.7  . M82 is about 12 million light years away for comparison. There are not much information available about these clusters, just two more among plethora of others. Faintest recorded galaxies in this image are about 22mag.

21-22.04.2019, Meade ACF 10" f/10, AP CCDT67, EQ6, QHY163M, L 400x60 s, gain=100,  suburban sky, seeing and transparency good.

Always nice to see something different.

Thanks for pointing these out,and well done.

Very nice. Have you seen this 63 h image? It confirms your data.

Uh, this is amazing image. And clusters are well defined there - I have not seen this image before.

Amazing what "amateur" astronomers can do with modest kit.........fantastic image!!!

Super stuff Drjolo and keep them coming.  Amazing work, well done.

Your website is great BTW.  I have just acquired a CCDT67 for my 14" Meade and will give this a go.  Do you use autofocus for your setup?

[drjolo]

Thanks

Yes, I use autofocus and it works well. However I have separate crayford focuser attached, so I do not use OTA focusing knob at all. Also temperature compensation works well in this combination.

Good to see an imager using their imaging to go beyond 'just' producing a nice image; to do some astronomy in other words.

And I combined image from the first post with some RGB data.

21-22.04.2019, Meade ACF 10" f/10, AP CCDT67, EQ6, QHY163M, L 400x60 s, RGB 80:50:60 x 30 s, gain=100,  suburban sky, seeing and transparency good.

PS - I do not remember why I made L frames 60s and RGB frames 30s. I probably had a reason, but it was late, and now I do not why
