I copied the full res file into PS CC and touched up the Micro Contrast with a Topaz labs plug-in (Topaz Detail) and it really lifted the image off the page, without spoiling the natural look and feel to this stunning region.

Awesome. I have topaz lab 2.0. Which settings are you using?
I copied the high res jpg into PS CC (OMG) and di a full res 1024x1024 crop and saved it as a JPG.
I then used Topaz Detail, Micro Contrast I set to Default on a new Layer and then set that Layer to 67% so only 67% of the effect was active and saved it as the 2nd JPG here.
Tres bien Marc, are the extra fields part of a mosaic?
Meric beaucoup George. That's one field. I offset it to see bit of the LMC bar and hadn't planned for a mosaic but you're right. 4 panels would cover the whole area nicely. Will do.

Thanks Geoff.

Thanks a lot Greg. I bayer drizzled x2. That helps a lot with undersampling with the oldQ/QHY8 @ 7.8um ~3asp so you get a lot nicer stars by doing this way provided you keep your focus and guiding super tight.

Hope you can see the subtle difference.

Thanks for that. I can see it gives a little boost to the stars and other areas. Will play with the settings.

I'll need to learn this, perhaps you can mentor me on the best way to do this.

It's super easy. Here's the PI project files in a zip with my settings. Just replace source frames by your own and the directory structure and folders to suit. I always use the same flow.
Very nice Marc! I'd love to see mosaic once it's done. If this teaser is anything to go by it'll be epic
Bayer Drizzle certainly does help, I've got a 3x3 bayer drizzle going right now! I wouldn't generally recommend a 3x3 though, apart from needing at least 50 frames to get good sampling (otherwise it can leave some nasty things) I'm doing it purely to fix up some star shapes.
I've found that even if your sampling is pretty good, thinking here of using your QHY8 with CN-212 or 8" F/4, bayer drizzle at 1x1 sampling still helps improve things from just a standard stack. It doesn't increase resolution but helps give a more natural placement of colour and should (in theory) give a more accurate PSF and be closer to what a monochrome sensor would in RGB images.
One of your best. The Tarantula looks superb, but the overwhelming feeling of stars - the thing being in a galaxy, not just glowing gas - is preserved.

Never tried on oversampled data but will have to try when I use the QHY8 with the CN-212 I'm at 0.61 asp. The bayer matrix is a killer for details.

Thanks a lot Mike. I saw the progress on the windows. Exciting times.
Nice to see so much of the Tarantula. As I mentioned in Bart’s shot, pictures like thes really show up the advantages of a nice wide field. Colours and definition are good. All in all a top shot
Impressive Marc. Definitely benefits from downloading the hi res version.

Thanks guys.
Off to France in the Pyrenees for a month this Saturday. Taking the SONY NEX-5 and polarie with me
