    Wonderful colours and you have done a great job keeping colour in these very bright stars whilst also capturing so many faint ones. I have not noticed in photos before that so many stars can be found in the Coal-sack. Well done!

    M81, M82 and the IFN

    Wonderful image Sara - I love the colours and the detail you have brought out in the IFN. Well done!
  5. Thanks for that. Cheers Mike
  6. Thanks for that! I am quite pleased with the way it turned out. Although ... The colour balance was a challenge and I'm still not sure it is "correct" - the problem I had is that there is no neutral area that I could use as a reference to remove the light pollution. Even the dark areas are really red! Also, looking at other deep images, I think that the blue tint at the far left is not due to reflection of blue star light from interstellar material :) - I think it is probably due to the very strong stretch of the dark tones bringing out atmospheric flare from the bright star just out of frame - there must have been more dust/vapour in the air than I thought; it looked clear! Cheers Mike
  7. updated ( slight tweak to colour balance, a little brighter and tad more contrast )
  8. Thanks Rodd. I find it hard sometimes to set the right contrast - I calibrate my monitor for colour but the contrast is very different between my monitor and IPAD.

  11. Thanks Rodd Here is a further tweak. What do you think, better or have I over done it? Cheers Mike
  12. Cheers Carole - yes I imagine that it is quite low in the sky for you!

    The process you describe sounds right. By the way, In the past when I tried stacking the different channels it did not make much a difference. In the recent experiment I turned on the option of distortion correction. I suspect that this may have helped.
