M27 with the outer shell

[petershah (Peter Shah)]

Its been a while since I've posted... so I thought it was about time. M27 The Dumbbell Nebula showing its outer shell. Imaged with the William Optics 132 and an FLI ML-8300 in Ha, O3 and RGB and cropped in nice and close. Exposure times were 6hours of Ha, 6hours of O3 and 1 hour each In RGB total of 15hours. Imaged from the Roboscopes site based at E-Eye in Spain.

Thanks for looking

That looks great. Really nice vivid colours and great details. I wish it was higher in the sky for us.

That's beautiful, Peter; congrats!

My first impression was the look of the stars, they look worked on/shrunk? Otherwise, a wonderful and colourful result there Peter, very extensive outer shell structure, nice job

I agree about the stars--all the brighter ones have coloured halos. Nice detail in the nebula. As Mark said, it's a pity that it is so low in the north.

Thank you for your comments....I should have known better to try and sneak this one past you guys, You dont miss a thing...Of course you are both correct. I have given it a slight star reduction to help with the bloated stars and probably over saturated too. 132mm is a relative small aperture this combined with small pixels and an extreme crop. I might have got away with a longer FL and bigger aperture. or perhaps left the stars alone.
Ive included the full frame ...I have a big Dall-Kirkham that Im planning on pointing in this direction in the future better suited.

Brilliant image Peter, and I must admit I like the reduced stars as it makes the Nebula stand out a lot more.


To protect stars and stop them bloating etc I use StarNet++ to remove all the stars, work on the nebula, then add the stars back in, I do this in PixInsight....not sure what package you use.

Thank you Dave.....I mainly use Photoshop but Im starting to get my head around PI...it has some stunning tools

If you want to have a look at StarNet++ module for PI have a look at this thread https://pixinsight.com/forum/index.php?topic=13691.0

Great detail Peter and the colour is also spectacular. Nice work.

Thank you Paul...I think one to work on ...I will get some larger scopes pointing at it and see if I can get more detail and tighter stars.Wont be until next time around though.
