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
Number 1 with the orange hues against the blue star/s is my favourite version.

Best
JA

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.

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 didnt appear to dark. When you zoom in close they do actually have small bright regions although my 8 rig cant 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 1940s and did spend some time in Australia in the late 50s early 60s working with the Australian government with Astronomical research then moved to the US to continue his work. A very dedicated talented Astronomer.
Cheers
Martin

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
Im 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
Im going to busy getting my new rig sorted in June / July
Thanks again
Martin
