After getting the observatory automated I hit a major set back with the observatory computer packing up....so the past week I've been building a new one getting all the software installed and set up again....last night I managed to test it out and iron out a couple of bugs and all seems to be well for now.....I managed to grab a few extra frames for my N281 project....still working on it hoping to go much deeper....so for now this is it with an extra 2x30mins in H-alpha added with my pervious HaRGB data at 4x600s in Ha, 6x600s in red, 6x420 in green and 6x530s......cheers Peter

Some very nice detail showing there Peter! You ended up with a very similar colour balance to me: http://stargazerslou...1080_272223.jpg

It's very hard to avoid pinkish hues when adding in the Ha, but I find it's a trade-off between detail and pinkness!

Many thanks Lewis....To be honest I think its actually pink in colour, even in just RGB it has a pinkish hue. When you look at the amount of signal in the green and blue there is no avoiding it....my exposure ratio's are loosely based on a G2v star calibration to achieve as close to a 'true colour' as possible.
