M81 and M82

This image of M81 and M82 has been put together from LRGB and H-alpha data captured by me, and RGB data from Andrew Luck, collected over the last month or so.┬áIt was a bit of a nightmare combining everything, but the end result isn’t too shabby. This is the full resolution image which shows the HII regions in M81 quite nicely.

Last night was clear and moonless, so I took the opportunity to hook up my Atik 460ex OSC to my Equinox ED80 and try a couple of well-known targets. First was the Rosette Nebula in Monoceros. This is a stack of 36 x 5 minute exposures, processed in ImagesPlus:

I then swung the telescope round to Ursa Major to capture this grouping of M81, M82 and NGC3077. It’s put together from 23 x 5 minute exposures.

Well it’s only taken the best part of a month to do this! L, R and G frames were taken on 12th February, but tonight I was at last able to grab the blue frames during a break in the clouds to finish the image. Taken through the ED80 with the Atik, this is made up from 12 x 5min exposures through a CLS luminance filter, and R, G and B filters. I hope to be able to add some Ha to bring out some more detail in M82 next time the weather affords an opportunity.

Just before the clouds rolled in I managed to grab a single 5min luminance frame of M81 and M82. I shall look forward to having another go at this pair soon, and see how much more I can get out of it with a couple of dozen frames!
