M16 LRGB

[Mike Hawtin]

A bit late in the year for this one but better late than never.  Two panel C6 Hyperstar and Atik 428EX, Luminance per panel 31 x 300 sec and RGB 12 x 300 sec for a total exposure time of 670 minutes.  Thanks for looking.

Beautiful M16! Haven´t tried this one myself but it looks like you got pretty deep.

Very nice image.

Thanks for taking the time to comment chaps, Martin the Hyperstar certainly does soak up the photons, I'm not sure the depth is to everyone's taste but it is what it is and there is normally no need for noise reduction when processing these images.

Given that there is no Ha layer in this, the data is, indeed, remarkably deep. If you went for an Ha layer you'd be able to go as deep without having to process so hard.

Do you know the simple Ha-boosting trick in Photoshop? Just go to image-Adjustments-Selective Colour and, when it opens by default in the reds, move to the top slider left to reduce the 'cyans in red.' It often makes Ha signal 'pop' big time.

Thanks for the tip Olly, I'm not a Photoshop user but I expect there are equivalent techniques for Pixinsight.  I do have some Ha for this subject so I'll probably give it a bash soon.
