Guys...as most of the imaging boys at lostock were aware I was having major problems with noise on this target...I spent 2 nights just imaging this target with the same affect...I was using a UHC-2 filter which looks to have been the cause of my problem...the noise ratio was too high.
I had enough by the second night so I decided on the last night I would take an image without the filter with improved results....and considering I spent a full 2 night on this target I didn't want to waste another so I moved onto Orion.
Very dissapointed in this image but I said I will post it.
15 x 12.5 Minute guided exposure ISO800 on the ED80.
I have lost a lot of detail due to darkening and reducing all the noise and I mean noise heaps of it.....oh well next time I wont use the filter...saying this the UHC-2 filter works exceptionaly well from my light poluted skies in Brisbane...I now know not to use in dark skies...atleast I learnt something.
Hi Tony, Looks ok to me mate!!!
Shoot me a copy of your stacked, calibrated RAW (before any processing) & I'll see if I can suck anything more out of it... rob(at)star-mate.com
But honestly mate it looks awesome to me! Well done...
Cheers
Don't be dissapointed Tony, it's a great image. Don't forget too that the camera is not a cooled camera, it's summer so you'd get a bit more noise.
I think it's a very good shot, just learning as we go mate.
Shamefully I will give you a link to see a larger version that makes it look even worse....but only if you download my latest Orion Runningman image aswell...full jpeg version.....lol
Yep that M42/NGC1977 combo is a stunner... I took a little poetic licence and combined it with a 1min trap shot I took some time back. Took awhile to scale & rotate to fit (and it's still not quite perfect), but maybe you'll like the result? Maybe not!
Cheers
Yes theers plenty of detail there in the nebula. Did you try in camera noise reduction? I wonder how much of a difference it would make, though doubling imaging time.
