Triffid - calibrated reprocess

[monoxide]

Hi guys,
i thought i'd go back over my triffid data and use the flats i took for the carina shot, while not ideal its a lot better than not using any.
still a bit grainy but i think its cos i pushed it pretty hard in PS.
more data needed to smooth it out and bring out more detail.

Looks good other than the grain/noise.
But I would have thought that 100min of data would give you a very smooth image? Maybe camera settings need tweeking?
cheers Gary

Thanks Gary,
i had the gain set to 20 for this image and ended up dropping it back to 10 for the carina one which turned out a lot smoother.
