M61 & NGCs 4301, 4303, 4292
Hello Group
Only just managed to squeeze in enough clear skies to finish this image off.....in fact, I would prefer a few more hours. Very low for us SH imagers.....it never rose above 48 degrees, and average altitude was 45 degrees. Chucked lots of data away, kept the best for this image.
This is an LRGB totalling 11 hours of M61 and surrounds.
12.5" RC, STL11K, AO-L
I hope you like it

Really nice image.  I like it a lot.
(I would like to be able to capture and process something like this - maybe, I wish, someday,  )
Well done on a great image.
BTW - Has anyone counted the faint fuzzies in the background??

They aren't eggy stars in the background are they .. they are other galaxies
But isn't that what you expect from $16,000 scope and a $10,000 camera ?

Very nice Martin!
The framing with the other NGC galaxies really make it a lovely image!
cheers Gary

Thank you once again.
However, I appear to have missed a trick here. I am now working on a new-build 64Bit Vista box, and while I have calibrated my monitor with a Spyder, the web version of the image is not appearing as it should.
Here is the corrected image...which addresses the background which was too dark, and which brings out the outer arms of M61.
Thanks again
Martin

Ah yes that looks better.
I imagine our Milky Way looks exactly like this galaxy.
I haven't seen this one done before.

I had a quick look at this image last night Martin and thought the same and this is not a major issue but the background still looks a little unaturally dark too in this version on my monitor..?
A lovely rendition of this galaxy particularly given it's declination.

hi Martin,
great result in terms of colors! these are perfeclty balanced and very rich!
concerning details, I feel the galaxy does show many of it, but actually it looks a little off focus, or if the seeing was bad.
did you have to apply lots of smoothing filters to the luminacne...?

Wonderful image Martin, the detail in the spiral arms is very spectacular.

Hi Paul
Try this link, http://www.martinpughastrophotograph.../M61LRGBv3.jpg, I had the same problem as you when I clicked on the link in the initial post.
Oh and great job, as always, Martin.

Didn't see the previous version, but this is a lovely piece of work Martin. Its almost M83 like in its spiral structure. Excellent detail obtained given technicalities/difficulties. This is indeed nice eye candy.
