M82 in HaRGB

Hi all
I have finally managed to get out and do some imaging for the first time since mid February. It was also a chance to try out the H9 camera and 7 position FLI filter wheel which I got over a month ago. The image is of M82 using HaRGB with 20x5 minutes for Ha and 20x2 minutes each for RGB all unguided. Although the sky was clear I had to contend with a half moon all night as well as my neighbours bedroom light and the seeing conditions were fairly bad. Anyway, enough of the excuses, I am just glad to be able to do some imaging again. Thanks for looking, further details on equipment used is on my site http://www.imagingtheheavens.co.uk
Best wishes
Gordon

Not a bad rendition of M82 Gordon. Having imaged this myself, its a tricky galaxy to nail. The dynamic range is deceiving I found. I'm wondering if longer subs is the answer here - certainly for the Ha data anyway. Is your intention to start guiding soon or you happy with protrack? Which scope did you take this with?

Cheers

Hi Jase
This was taken with the Takahashi BRC-250. I will be doing autoguiding at some point as well as flats (which I've still not tried), it is a question of finding the time to get it all sorted out. Currently I still use the Paramount as it came out of the box so no PEC or protrack has been used, it is down to getting an accurate polar alignment. I did think that the 5 minute subs of Ha may be a little short but as the scope is f5 I thought I'd be able to get away with it. Probably try for longer next time round
Best wihes

Hi
When I had a look at this image on a different computer and monitor there was a gradient that was evident that I couldn't see on mine so I have tweaked the image a bit to remove most of the gradient and also done some mild sharpening and small adjustments of the curves to extract a little more detail. Thanks for looking again.
Best wishes
