Finally got around to processing some data from earlier in the week. This is about 2 hours on NGC5128 taken with the QHY8 and 10" Newt. I've had a few goes at this in the past year but have never been happy with the result. This one seemed to work out better than earlier attempts.
full res version here:
Comments welcome, thanks for looking.

Not a bad Cen A at all :thumbsup:
You have the double lobe coming through in the bottom half, this is the first hint of the shells in the halo (http://www.pbase.com/strongmanmike2002/image/108349883/original), nice :thumbsup:

Looks very good, Peter! Another subtle and difficult target. Was that taken from the city?
23-06-2012, 03:27 PM
Very nice Pete, love the star colours. Did you process this with PI?
23-06-2012, 03:57 PM
Stunning! Love those star colours. :)

Thanks Mike - what is the double lobe you refer to?
Cherrs Rick - yes taken from Ashgrove.
Thanks Geoff. I'm pleased with the way the stars came out. Need to rework the sky background as it looks a bit blotchy with fresh eyes. I used DSS and CS3 to process as I've been having some problems with PI working on the XP machine. Might have to get a new laptop after astrofest.
Thanks JJJ. I was hoping to see some of the blue in the galaxy dust lane however I am happy with the star colours in this one.

:) Really very good there Peter espically considering NGC5128 is 20million light years's away , as Nettie said the star colours of the stars in our milky galaxy are really nice , so well done.

Very nice image Peter. Could do with a little less exposure at the core but the detail is there and we'll captured.

Superb shot Peter. Practice makes perfect. Really very nice. Gorgeous colours. Definitely one for the cool wall. :thumbsup::thumbsup::thumbsup:

Thanks Brian. It has always been one of my favorite galaxies and is well placed at this time of year given my limited horizons.
Cheers Allan - probably need to improve my processing a lot as I have plenty of subs and the majority of them look pretty good.
Thanks Marc. Wouldn't it be nice to make every photon count!

Amazing depth in your image Peter, and as others have said the star colours are well preserved. Thanks for the view.
24-06-2012, 01:00 PM
Yes - it needs reprocessing.
It has a purple cast & the background is too blotchy.
Imagine what Louie could do with your data?

I missed this somehow. It's awesome! As others have said, nice star colours, and I'm surprised how much of the fainter glow you're getting out of it. Really, really nice.

A great photo Peter.
Colours are amazing.
25-06-2012, 09:18 AM
It's that slight buldge on the left side of the lower half of the Halo.
25-06-2012, 09:19 PM
Thanks for the feedback.
I've now had another go at it from scratch and hopefully have addressed the cast and blotchy background.
Ahh - now I see it - thanks for the heads-up Mike.
Spent quite a few hours tonight reprocessing from scratch with some more subs from the subsequent night making this 38x5mins.
Here's the new full res version:

Nicely done Peter
Good resolution and good colour balance.
25-06-2012, 09:52 PM
Wow thats a beauty. Nicely done. Impressive with only 2 hours of data.
The repro looks great with less blue. Nice work :thumbsup:
26-06-2012, 02:41 PM
That's much better - I knew it was good data.
Well done - I think we would all hope to do as well. :)
26-06-2012, 08:07 PM
It's stunning Pete. :)
26-06-2012, 08:19 PM
Great repro, Peter!
Stunning result from the city Peter. Congrats! The 10" is really showing its merit there.
I found the first effort particularly striking except for blotches in the outer sky background as you've said. Who cares though when the stars look so nice and you have so much of the galaxy there!
27-06-2012, 02:10 AM
Really nice ... congratulations...
All the best,
27-06-2012, 05:59 PM
Thanks for the feedback Martin.
Thanks Chris. I added a bit more data to this version so it is now 3 hrs. It still amazed at what can be done from a light polluted site in such a short time.
Cheers Simon. It pays to take time processing and look with fresh eyes the next day.
Thanks for the feedback.
Cheers JJJ. I'm having a lot of fun with the gear now - just a few small changes to make :D
Cheers Rob. I pushed the original one too far in search of the blue around the central dust band. I was surprised to see what I think are a few small background galaxies starting to appear.

Nice work Peter.
15-07-2012, 09:33 PM
That is a beautiful 5128 Peter. :thumbsup:
Very colours, and lots of detail. Well done.
