OK, last image for the night...

Back to the galaxy clusters I enjoy photographing so much. This is the first time I have done one in colour. I'm quite happy with the result considering the relatively short exposure time (both individual and accumulative). I've spent a couple of hours processing this guy, working out a lot about LRGB imaging which is still quite new to me. In that time I was taking more images of the same field, some 20 min exposures. So I will do another version later with all the data.

10 minute exposures, 4 of L, 1 of each of RGB. I think I've got enough now to easily double that when I re-do it.

I haven't labelled the PGC's yet, might do later. There's a few around mag 18.5 - 18.9.

:hi: Roger, great shot! attached is an image taken off google, the star in the top of your image of NGC 3271 seems quite bright and is not visible in the attached image other images I have looked at.
In the attached image there is a slight brightening in about the same position so it could be the star in your image?
I have checked quite a few images and yours shows this position the clearest. What do you think?:thumbsup:

Thanks all, sorry about the delay in reply - been out in the country doing astrophotography last night.

Ron - which star do you mean, the one near the nucleus ? If so, I suspect it's simplya case of processing. I've managed to process mine without burning out the core, bleeding in to that star like the one you attached has.

Or am I missing what you're meaning?

Roger.

Yes Roger, I am observing that your image is the clearest that I could find,as you say your core is not burnt out,you as an astrophotographer is a better judge of the image than me.
As I mentioned that slight bump might have been that star in your image.
Anyway I always check your galaxy images for S/N, and copy them for my S/N files:thumbsup:

Ahh :) I misread your message - blame it on sleep deprevation from 4 late nights of astronomy straight :whistle:

That's nice to know mine is relatively good compared to the other ones out there - I rarely spend the time googling to find others, but it is interesting to do so :)

Roger.

Great imaging Roger, just love those galaxies.

Cheers
