Hi All
This was taken over three nights and is of NGC281. It was taken with
Takahashi FSQ106ED at f5
Paramount ME
Starlight Xpress SXVF H9
autoguided by Lodestar and OAG
12x30 minutes Ha, 7x30 minutes OIII and 12x30 minutes SII using 5nm filters
The OIII and 3 of the SII sub frames were shot last night under a full moon, 9 of the SII sub frames were shot under very poor seeing and transparency conditions thanks to some very high thin cloud and half of the sub frames from that evening had to be rejected so I am quite pleased with the overall result.
Gradient removal was used but no sharpening, this was mainly levels, curves, contrast and a minor shadows/highlighs adjustment and selective colour
The full size high resolution version can be found at my pbase site at the following link
http://www.pbase.com/imaging_the_heavens/image/128797632/original
The Ha version can be seen in the image gallery of my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/)
along with a previous attempt at this object with the HST palette 2 years ago
Thanks for looking
Best wishes
Gordon
