M45 to sho faint nebulosity


Post by Jockinireland »

This is a reprocess of an image I already posted.

This time using Scot Rosens DSLR LLRGB process (my first effort with that) to try to pull out the faint nebulosity. I think I've probably over done it a bit but i think it is still amazing to see how much can be pulled out of even mediocre data.

EOS1100D (unmodded), Skywatcer Star Adventurer mount
Vintage Pentacon 135mm lens
30x 90s @ISO800, 21X 90s ISO1600, 30X 120s ISO800 (total 2hrs 15mins)
Around 30 flats, darks, dark flats and 80 bias for each set of lights

And here for comparison is the one i posted earlier,

I'll be having another go at this sometime so any suggestions on how to improve it would be greatly appreciated.
