Martin, some really nice images here. I particularly like how the top-right bright star has come out so beautifully. I am just beginning to appreciate how challenging that side of processing is. Nice job!

Well done Martin on a wonderful image :thumbsup:
Number 1 with the orange hues against the blue star/s is my favourite version.

Best

Thanks Kuz
The Compose module in Startools together with the colour Matrix allows you to create some interesting blends with OSC narrowband data , they may not be scientifically correct but pleasing to the eye
Cheers

I think I like number 4 better. I think the boks have better contrast and the cloud “ wall “ on the right stands out better. Horses for corses though.

That is a wonderful image Martin I only hope I can do as well at some stage.

Yes I agree the Bok globules do appear more defined against the nebulosity in no.4
I tried to back off the dark Wavelet sharpening so they didn’t appear to dark. When you zoom in close they do actually have small bright regions although my 8” rig can’t resolve them that well.When I get my 10” in June / July the additional light grab and resolution should resolve them and provide more detail with good data
Born in the Netherlands, Bartholomeus Jan Bok discovered Bok Globules in the 1940’s and did spend some time in Australia in the late 50’s early 60’s working with the Australian government with Astronomical research then moved to the US to continue his work. A very dedicated talented Astronomer.

Pretty happy with the results for just over 2 hours of data
You just need some clear sky time with your incredible rig , dial everything in and start imaging
I’m sure your images will blow mine out of the water with that 2600MM
My 2600MC is a great camera but I have this anchor called a Bayer matrix so I need 4 times the data as a mono to get somewhere close.
Mono is on my radar for late this year early next year
I’m going to busy getting my new rig sorted in June / July
Thanks again
Martin
