Hi All
I had a go at this a while ago on a cloudy night just using Ha and as it was clear tonight (up till 2am anyway) I thought I'd have a go using the SII, Ha and OIII palette also using the Ha as luminance. I had originally planned 12x10 minutes on each channel but fog and cloud came in after half way so I ended up with 60 minutes per filter. I was intending to start autoguiding this week and I have my guiding scope but I was having trouble with some conflicts and calibration so the subframes are still taken unguided, the frames are dark subtracted using 10 darks median combined, the subsequent combined master frames were colour combined in maxim dl and processed in photoshop, no bias or flat field frames were used (I will one day), the colour balance may not be spot on but I am pleased with the result, I hope you like it. I have included a widefield and close up
Thanks for looking
Best wishes
Gordon
PS Hope everybody enjoyed Kelling Heath

wowee. that is a very pleasing image.. Despite the SHO color pallete its still a very subtle looking area of the sky... I find at time SHO images are very bright and in your face, which on some targets, is fantastic, on others, its not so great....

Thanks for sharing your image Gordon.. Very well done.

Looks good, shame about the bluddy cloud and fog...I hate fog, it's a real slow silent imaging session killer :mad2:

Looks like autoguiding is almost not necessary really.?

WOW! What more can I say. I agree about the fog. That and high level cirrus.

Thanks for the comments, following some tips from a friend of mine I had a go at tweaking the image a bit in relation to levels, colour balance and sharpening, here is the closeup, the widefield is on my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/)
I like this one better, what do people think?
Best wishes
