Very nice collection of galaxies and a perfectly clean image For some reason I'm finding the blue of brighter stars distracting in this image, I don't find that in your others - Fornax for example. Might just be me

So glad you all enjoyed the image, not a vibrant coloured nebulous region I know but there is something sobering about a field like this, tends to make you contemplate and imagine rather than say "wow what a sight"..?
Entering the LSCC club is pretty special I must say Ken, I remember poo hooing CCD's back in the mid 90's because the chips were so small in the amateur market. After making extensive use of 6X7 film in the 80's, it is nice to finally have some decent film sized chip real estate
Yes, Guy, imagine this camera on a 12" F3.8.... ...imagine all the little problems, issues and quirks there would be to iron out too 
Rich, I am reasonably happy 
Marcus, the Robo Focus seemed to have no issues but I don't controll the RF via my computer instead I simply use the remote hand control to move the focuser in and out so I am not sure if the weight of the kit would affect software autofocus routines and repeatability..?
That cute little galaxy in the top left corner with the blue extensions is a Polar Ring Galaxy: http://apod.nasa.gov/apod/ap990510.html
Thanks again everyone
Mike

Absolutely awesome!!!!!!!!! I stopped counting at 30 on the 900kb image. Didn't even start on the full image.
Makes you wonder how many out there are looking our way?
Cheers and Thanks,
Duncan

OK, I imagined it...and that's about it  Would take a lifetime and you would need to do it from the Andes to get enough clear nights

OMFG = Oh My Fine Galaxies...? 
Ladel them huh..? No but I'll name'em
Spiral Steve, Polar Pete, Side-on Sam, Irregular Ian, Cigar Bob, Friggin faint Fred, Redshifted Roger, Eliptical Erol, Barred Barry...and the list goes on! Then there's Sula, Nula, Tula, Rula...oh! and Gabby!

Yeh it's a big chip mate but still way behind the size the 4" FF was designed to cover
How's things anyway..?

For some unknown reason I had an issue with my Lum shots with a touch of egging happening for some reason but it is only noticable at full res, funny, the RGB subs were all pretty well perfect... The egging in the final LRGB was really only minor so I left it as is, de-egging causes more issues than it solves usually anyway....so ignore any eggs if ya notice them.. baulk begurk!
Warning, the files from this 16mega pixel beast are big and given the fov is some 1.65deg X 1.65deg the tiny size of these 150 million ly distant galaxies (largest is still under 4') means to appreciate them one must look at virtually 100% size images really.
So here are a few 100% crops (around 1Meg each) and a 50% size full frame (4.5meg) for a bit of surfing oportunity .
Full Frame 50% size (4.5meg)

Cool galaxy grouping 2 (500k)

And if ya just wanna see it all in one go have a surf around the enormous full 100% size full frame 16meg image here:

That's a beauty, Mike. Beautiful field and lots to take in, that's for sure.
I look forward to seeing it take something nice and colourful next, too

Its a MASSIVE chip, but its no 6x4 medium format film! That 4" FF will do you a decade or so longer I'd assume...
Things go ok mate... Been a bit quiet of late with my time being occupied by a new job etc.. doing 12 ~ 13hr days etc...
Looking forward to seeing some narrowband imaging from this big rig!
