M27 - Dumbell Nebula

[CoolhandJo]

Hi all, with my close encounter with a funnel web spider last imaging run I have moved to make my rig as auto as possible (to image from the safety of my indoors!). I am about 75% there and have automated the alignment and guide star selection process. Unfortunately the guide cam (which acts as a wide filed sky scan to find alignemnt stars) is too high in arc pixel sampling compared to my imaging scope so I had guiding issues.

This image of M27 is Ha:Ha:Oiii 60:20min (10 min exposures)

Even though I use a Light pollution filter for my suburban skies I was delighted to see the outer skirt starting to show.

I had to use a star rounder tool on this one until I get my guding sorted out.

Comments welcomed.

Amazing amount of nebula in your image Paul. All the best with the automation.

Nice! What scope did you use?

Cheers,
Rick.

Thanks Lester / Rick. I used an 8 inch F5 Newt with Atik 314l+

I really like this. It's one of those narrowband images that really convey a sense of "she's gonna blow!" (even though "she" has of course....;))
Glad you posted it Paul, even if the stars not perfect. :)

Despite some slight guiding issues, there's lots of details there.

I know it's a narrowband image, but I tinkered briefly with it, removing some of the red cast and giving the blue a little more luminosity to bring out the envelope some more, I won't post such , but have a fiddle yourself and see if it works for you.

Thanks Rob! Ther are many ways to process this (using different blending methods) but this method brings out the central nebulisty quite well IMHO

Thanks Clive - yes - pleant of detail to play around with! I will definately give it another go!

Hi Paul,

I really like the colour and you have captured some amazing detail for suburban Sydney.

Like your "remote control" ideas.


Thanks.

Ross.

Shame about the guiding glitch. The details are awesome. :thumbsup:
