Nice image which has captured the really faint extensions of these galaxies but you sould do a Sidonio as the core details are burnt out ( if you dont mind see http://www.iceinspace.com.au/forum/a...e.php?a=153920 ) and I feel these details are what turns this galaxy into a very interesting object as the dust seen at the core has apparently come from a recent merger with another galaxy which has led to the distortion seen.
But I really like the very, very faint stuff captured in your image.

Thanks Allan. I did a repro and you are right there was a lot of detail in the core area. In fact the shell structure came out very clearly so the remnants of the swallowed galaxy are visible plus the dust lanes and shell structure very much like the Cent A super long exposure images show.
You've certainly picked up a lot of faint outer structure from this super interesting galaxy Greg, well done. That one is on my todo list as well, it's a lovely interacting galaxy.
If I should say something it would be that there is still more dust detail in the bright core area, the dark pattern extends right across the core from one side to the other, like Cen A. Maybe it's possible to enhance it, or is the core already very bright in the raw data? (I don't know as I've never tried imaging this galaxy) Hope you don't mind

Thanks Rolf. I did notice that in one play with the data but it was very faint.
OK, I worked on that and got more of the dust lane. Thanks for the tip. Same links.
Greg.

Your repro has really made a difference to the core, has the whole package now!
Cheers,

Thanks Justin. The repro made a big difference. Finding some CDK data I already had also helped.

Thanks very much Glen. I was happy to get the data. It was windy on a couple of nights and the big refractor is prone to wind. I plan to modify my observatory next time I am there to make it windproof. I had a bright idea as I was leaving last time how to handle it easily.
