xanthic Posted April 18, 2014 Share Posted April 18, 2014 (edited) I got guiding worked again, after much frustration the other night. This is not a finished piece of work, I think I need to double the number of subs or maybe even start over with long subs before I even consider grabbing the RGB. I had quite a severe gradient, which is fixed here. I think I had a lot of LP which has degraded the image, probably another filter to buy! All comments welcome. 19 x 300 sec Luminence, ED80 & Atik 314L+ Edited April 19, 2014 by xanthic Link to comment Share on other sites More sharing options...
Guest Kheldar Posted April 18, 2014 Share Posted April 18, 2014 (edited) Looking good All your detail will come from the L, rule 2 is always more data, more data, more data! When it comes to the RGB you can get away with less and shorter subs Without seeing your histogram for the raw subs is say you're about spot on at 5 mins, nice detail showing through Edited April 18, 2014 by Kheldar Link to comment Share on other sites More sharing options...
catman161 Posted April 18, 2014 Share Posted April 18, 2014 Looks good Leigh-look forward to seeing the added colour. When you zoom in-going from left to right is a diagonal line, what's that from? Link to comment Share on other sites More sharing options...

xanthic Posted April 18, 2014 Author Share Posted April 18, 2014 Yeah, satellite trail. I'll drop that sub out if the Sigma clipping doesn't fix it. Link to comment Share on other sites More sharing options...

xanthic Posted April 18, 2014 Author Share Posted April 18, 2014 Would that just be for luminence? Link to comment Share on other sites More sharing options...
xanthic Posted April 19, 2014 Author Share Posted April 19, 2014 (edited) I collected some more data last night. More trails, even though I used sigma clipping. This is the result of 52 x 300 sec luminence. I'm stil not happy with the contrast and there seems to be a fair amount of grain in the pic (noise or bad contrast or just need even more subs?) There are also some odd "scratch" in the image, which were not there in the first run. I suspect I need to repeat this with an LP filter. Any thoughts?

dawson Posted April 19, 2014 Share Posted April 19, 2014 Very tidy! Do we live under a satellite flight path? Looks great. Well done. JD Link to comment Share on other sites More sharing options...
