Co-incidentally Mark has just done the same image (only his is much better).

I went to a small star party in the Cotswolds last week Bortle 4 and the skies were clear for the first 2 nights.  This is the first of 2 images I managed to get.

Because i don't do much in the way of LRGB imaging I found this particularly difficult to process, but Peter Shah was at the Star party and gave me a few tips.  It didn't help that I stupidly forgot to put the cooling on (Gun to head).  Also 2 sides of a Median to process just to add to all the problems.

Like Mark i have been wanting to get these two targets for some time, but unless I did a Mosaic and with my LRGB opportunities this would be somewhat problematic, so I decided to use my Samyang lens.

Atik460EX and Samyang135mm lens @ F2.8
Lum 23 x 600 (3hours 50mins)
RGB 14 x 150secs binned each filter (35m each) total 1 hour 45 mins
Total imaging time 5 hours 35mins

That's come out really well Carole!

You have a larger field of view than my image.  Which camera and lens was it and what f-ratio did you use on the lens?

Really Sorry, I forgot to put that.  It was my Atik460EX and Samyang135mm lens @ F2.8
Will now amend the first post. 

I had an even bigger FOV but due to changing my equipment around, I messed up the orientation of the mounting of the Samyang set up and had a rather large amount of rotation each side of the meridian, so this is cropped to get rid of the overlaps.

That's really rather good Carole. Maybe you shouldn't bother cooling that camera!

Thanks Duncan, lol, yes I thought it would have been much more noisy.  But I won't take that advice ha ha.

I must say i have been quite chuffed with how it turned out in the end, but it was a challenge processing it.  especially 2 sides of Meridian for all channels and I don't get much practice with LRGB.

Oh Wow, got a further message from Astrobin, I have actually been selected as a TOP Pick, these are the shortlist for IOTD. 

Congratulations! Your image was voted Top Pick: Iris Nebula NGC7023 and Gyulbudaghian's Nebula LBN468


Only my 3rd such award in 10 years.  Dead chuffed.
