The Network Nebula (aka Eastern Veil Nebula) Posted by: Stephen - 2009-01-14 00:39:56

Rob Hodgkinson, of South West England, is a very talented astrophotographer. So when I looked at one of his latest images I knew I had to post an article here on astroslacker.com. Just looking at this image makes we long for the day when my astro-savings account is ready to blow open and I can finally get that astro-physics monster scope!

Anyway, Rob has captured what he believes is a bow shock within this processed image of the supernova remnant. I would really like to hear from some professional astronomers, to see if that is in fact what he has captured. If you have any information you can contribute, please feel free to post a comment.

Rob Hodgkinson: This was imaged on the 25th and 29th November(Ha) and the 9th December(OIII). It was an early evening target before Orion cleared the trees and could really do with more subs I think, especially the OIII. I've been playing around with it for a week or so, and managed to produce a highly over-processed version, and last night went back to the beginning and started again.

This is Ha (red), synth Green (Noels' actions) and OIII (blue). No luminance layer was used.

Imaged with my WO zs80FD
Atik 16HR
Astronomik filters

Ha 20 x 8 minutes
OIII 9 x 8 minutes
Subs all unbinned.

One side effect of pushing my original attempt at processing too far, was that I seem to have caught what I think is called a 'bow shock' (correct me if I'm wrong please!) I've cropped this section and posted it too, as I find it very interesting to see the red Ha shockwave, and right behind it the blue colour from the Oxygen. This has Ha used as luminance.
