Thanks Louie. I am working on it. There's some nice luminance there.

Thanks Roger. Completely dark skies and often good seeing helps a lot.

Really nice image Greg. It looks like that spiral arm is being pulled up by the companion galaxy, very cool.

Thanks Rolf. It is a good example of a distorted spiral.

I've added 200 minutes of CDK17 luminance data with a Proline 16803 to the image.

Its brought out more fine detail in the galaxy central area. Same links

Thanks Mike. I caught some good seeing on several nights at home with the CDK. Unfortunately it was before I put in a new primary mirror baffle and there was a reflection arc below the galaxy. So it was handy to have redone it with the TEC at my dark site.

Nice improvement, Greg!

Cheers Rick. Yes the luminance data was nice. I got some good seeing during that period.

Hi Greg,
That's a great result on a tough target.
The CDK17 has allowed you to zoom right in.
I'd be tempted to do a 3 x drizzle stack to try & get some more out of the data.

cheers

That's even better Greg, nice work. One can never have too much data

Very nice Greg. The detail is beautiful.

Thanks Allan. Is there a link to a reference on how to do that? Its something to do with upscaling and stacking isn't it?

Thanks Rolf. That is very true. More is always better.

Thanks Lucas. I think I'll be doing combo images like this from time to time.

Greg,

Thanks Allan. Is there a link to a reference on how to do that? Its something to do with upscaling and stacking isn't it?

Yes exactly that.
It's available in Deep Sky Stacker.
I normally use it on little galaxies & paste them back into the main image.
You can normally get a little more out of the data.

The data appears to have improved an already excellent image. Would love some clear skies - can you send some up to Brisbane?

I tweaked the colour on this one using the Lab colour tehcnique. It brought up the blue spiral arms a lot more.

Looking better now Greg,
you'll be able to have some fun with LAB colour -
what it does is amazing - but it's easy to overdo as well.
