I decided to redo this one to see if I could do something about the
halos. In doing so I found a note "check 11th frame--bumped scope plugging in dew heater". I do recall the alarm going off saying it had stopped drawing power. That usually means the cigarette lighter plug has pulled worked lose again. I vaguely remember the incident. Yep, frame 11 was horrid and since I did a pure average combine (didn't dither, besides that costs me asteroids which I like so I rarely do a noise reduction combine. Should have this time it appears. I redid it this time with Sigma Reject as there were no asteroids and the elimination of frame 11 just to be safe. This helped the halo problem as well as the loss of the dew heater seems to have added to the halo problem and that was mostly on frame 11. What was on the others was eliminated by the combine. Still have the gunk but think this a major improvement. Other than going from 12 to 11 frames the data on the original post is good. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

Much better - not as saturated and has more detail.

Even with only one bad frame it is amazing what it can do to a stack
with average combine! Beside the bump the corrector dew made a total mess of that frame. Doing this 8 months after it was taken I totally forgot about that bad frame. Usually I move them to a "Reject" folder but just wrote the note, something I never do. Still can't figure out why. I used the same RGB image for color so the saturation was the same. Also I used the same set of curves to process the L image. Only difference was the missing 11th frame and since 10 had a bit of dew I used sigma reject for the stack. That did reduce the glare around the brighter stars over an average stack. Rick On 8/17/2010 11:26 AM, glen youman wrote: Much better - not as saturated and has more detail.

pretty nice looking monkey knot Rick
