Wow Dave. That's a set of images to be proud of.

That is definitely an improvement. What process did you use to reduce the noise? I used MultiscaleLineartransform on the Ha component on mine. perhaps not enough.

I have to say I'm not happy with the Ha data overall. I'll probably revisit this as soon as it's in my FOV from my back garden but with 20m exposures

In the meantime I have reprocessed and come up with this which I think is a little better.

Good stuff. Thank you!

Sure thing, The HA was taken at a couple of camera angles hence the crop. Thanks in advance for the assistance. masterLight-BINNING_1-FILTER_Green-EXPTIME_60.fit integration_Ha.fit masterLight-BINNING_1-FILTER_Blue-EXPTIME_60.fit masterLight-BINNING_1-FILTER_Red-EXPTIME_60.fit

Afternoon All, This one has been quite a while in the making as it seemed to get brushed to the bottom of the imaging pile, I finally pulled my finger out and finished off taking the RGB subs for the stars. and couple of extra Ha subs. https://www.astrobin.com/psc4hq/?nc=user Antlia Ha 3.5nm 36mm: 112x360" (gain: 139.00) -15C bin 1x1 ZWO 36mm Blue: 16x60" (gain: 139.00) -15C bin 1x1 ZWO 36mm Green: 16x60" (gain: 139.00) -15C bin 1x1 ZWO 36mm Red: 16x60" (gain: 139.00) -15C bin 1x1 Please do feel free to critique, it's mostly why I upload these as it's the best way to learn.

That was nice clean data to play with and gradients aside a great image. Here's my take on on the data after giving it a quick process in PI Cheers, Wyvern

63.5mm produces a nice flat field for me.

Yes indeed. It is now fully operational and works really well. The the main issue with the stars was simply backfocus, the 31mm adapter tht comes with it is just too long for my scope so I had to buy some adapters and m48 spacers. The second issue I found was that this camera does not like being connected to USB hubs or extension cables, or at least mine didn't.

Afternoon, Thought I may as well throw my hat in the ring as well. I used a bit of a custom channel mapping with this one, but it's roughly R=Ha, G=SII, B=OIII Unfortunately I don't really have a process to share as I tend to just do stuff until I like the look of it. Final polish was in photoshop which was just some levels, saturation etc. Wyvern

Thank you for all your Kind comments!

After a few pretty nice nights I've managed to capture M31and M33 in HaRGB and M45 In RGB M31 20x R 240s 20x G 240s 20x B 240s 20x Ha 300s M33 20x R 240s 20x G 240s 20x B 240s 20x Ha 300s M45 30x R 240s 30x G 240s 30x B 240s I'm liking how each has turned out. Feel free to pixel peep and be brutal Wyvern
