SH2-103 (Veil nebula)


Recommended Posts

I had originally decided to attempt my second Hubble Palette image but abandoned this due to the high noise levels of my SII data.  So, changing strategy to a bi-colour approach, I mapped the Ha and OIII data to red and blue, respectively, with a synthetic green channel generated via Noel Carboni's PS actions.  I could have really done with capturing much more data but decided to see what I could process out of the noisy subframes.

 Apart from the filaments of the Veil nebula, I  was quite pleased to see what to me looked like a flaming skull (bottom left) and a small blue lightning storm (bottom centre). Constructive criticism would be welcome :happy11:

LIGHTS: Ha: 11, OIII: 6 x 1800s; DARKS: 30; BIAS:100, FLATS:40 all at -20C.

This is a lovely take on a fascinating object - what telescope did you use?

Thanks Steve, the telescope used was my Skywatcher ED80 DS-Pro, with the matching 0.85x FF/FR. Used in conjunction with my SX Trius 814 camera, gives me an imaging scale of 1.46 arc seconds per pixel which seems to work well for DSO imaging.

NIce work - love looking at same object at different focal lengths - different details and structures become evident.  Nice work.


Thanks Paddy.
