Ngc5101 ngc5078

[cometcatcher]

NGC5101, NGC5078 and friends. Two galaxies far, far away (about 90 million light years) in the constellation of Hydra. There are numerous other galaxies in the background also.

GSO 10" F4 Newtonian, 494 x 30 seconds unguided, Full spectrum Canon1100D, Baader MPCC MKIII, HEQ5 Pro.

Had to image this after seeing Lee's excellent image. APS-C view is a lot wider!

Very nice Kevin,
you've pulled mag 12 galaxies out by dividing the noise by 22
with a tremendous 494 subframes,
& to do that with no guiding & a DSLR is amazing.


cheers

Thanks Allan. Taking advantage of the rare clear cool nights.

Looks really good Kevin on Astrbin very nice I like it a lot

Thanks Martin!

[Atmos]

An excellent image Kevin! It is still only four hours of exposure so it's not much but you've captured them really well!

I'd love to see what you could do with 20 hours ;)

[cometcatcher]

20 Hours is half my imaging for the year! I know, I'd like to do those sort of times also, but not in Mackay. I would only get a couple of pics a year.

[Slawomir]

A very nice image Kevin! I see you are not far away from us :hi:

[cometcatcher]

Not far at all! Maybe we will meet up sometime. Skies in Prossy must be dark?

[h0ughy]

what an awesome shot! i love what you absorbed on the chip

[cometcatcher]

Thanks Dave. Glad you liked the absorbtion. :lol:

[topheart]

Nice!
Well done!
Cheers,

Lots to see the Kevin, well done!

[multiweb]

Really cool field. A lot of variety, beaute colors and structure. :thumbsup:

[Placidus]

Excellent work, Kevin! Beautifully acquired and processed.

[cometcatcher]

Thanks Tim!



Thanks Andy. Yes there's a few things going on in that field. More than I first expected.



Thanks Marc! The yellow stars in the field give it a nice diversion to the galaxies.


Thanks M&T! Looks like the cooler weather helped too in keeping the noise down.

[codemonkey]

Looking good Kevin! A much wider field that with my tiny sensor. One suggestion for improvement is that the field looks a bit vignetted. I'm not sure what you're using for processing, but if you use PixInsight you could look into the DynamicBackgroundExtraction process to help with that.

[cometcatcher]

Thanks Lee. Ah yes I see the vignetting now. I usually correct that in PS (don't have PI). Must not have had enough hours sleep when doing it. ;)

[RickS]

Interesting field and a great result, Kevin!

[cometcatcher]

Thanks Rick! Saw a 50 hour version on astrobin. Made mine look a little underexposed. ;)

[strongmanmike]

Sheesh missed this one too :question: :screwy:...another nice shot Kevin, they are a great pair and again lovely colour, you are really churning out the vistas huh? :thumbsup:

Mike

[cometcatcher]

Thanks Mike! Making hay while the Sun, er I mean sky is clear. :D

[raymo]

Wow!!!

I have a new revision. My memory is so bad I forgot that I took this galaxy pair last year. So I added them both together for a total of 1632 x 30 seconds or 13.6 hours. That makes this the most number of frames stacked for a deep sky object I've done with a DSLR.

New revision at Astrobin ---> https://astrob.in/349708/B/

[topheart]

Wow!
A very nice revision!!
Cheers,
Tim

[gregbradley]

Beautifully clear image.

Greg.

[raymo]

Super WOW!!!
raymo

[cometcatcher]

Thanks Tim!



Thanks Greg! Longest one yet.



Thanks Ray! It's super crazy! When I get an astro cam I may even take more subs since there's no shutter to kill.

[raymo]

I wonder how a 10,000 sub effort would turn out, and also at what point would no further improvement be seen.[Maybe we will find out].

[cometcatcher]

10,000 x 30 second subs is like 80 hours. I don't think I have the patience or clear enough skies to do that. At least not in one year.
