Thank you everyone for your nice words, I appreciate you having a peek and leaving a comment!

It turned out to be quite a hard night’s work – the seeing was very poor and at 3760 mm efl, the somewhat dim light was being smeared to such an extent that at one stage, I thought that I had slewed to the wrong object as Triton was not immediately obvious!

I was surprised at Neptune’s somewhat greenish tinge, straight out of the camera. I had the R:G:B ratio set at the default of 1:1:1 in CCDStack where I assembled the LRGB. The filters are the Astronomik RGB Type II. Just reading around a little now, makes me think that 0.65 : 0.98 : 1 might be more accurate pending a calibration run down the track.

Cheers

Dennis
