Since my first light of my ST10, I've been trying to fix up some of the images that were greatly affected by dew... this is really an intermediate repro posting, as its still not complete.. but I thought I'd post it...
Heres the M16 that I posted last weekend with funny looking squares and random blurryness throughout the frame caused by dew. the second image is the same data, except I set deep sky stacker to use only the best 50% of the frames... This resulted in the best 30x1min images going into this shot...
The third image was colourised using Noel Carboni's astro tools in photoshop.. Just a play around really.. not a big fan of it, but I figured I'd post it anyway...
In any case, There are no darks/bias frames applied here, as I wanted to test if I could get rid of the artefacts, I wanted to rule everything out... I will try stacking the same way again, but including darks and bias frames... Hopefully this will result in less noise in the image, but similar clarity...
Cheers for looking..
Ps. M8 and M17 are going to get the same treatment once I've figured out exactly whats causing the artefacts...
Alex.
