Wow...very nice Milton.
Glad it's working for you.
I was writing a detailed bug report for you about this issue because you know that i was a fanatic of that "wide" estimation (i asked for it).
For crashing bugs, a Crash Log / Crash Report is usually the best way to get things started, along with a general description of the problem. For stacking, a movie log is also required so I can set up a test situation with those options.
I needed some time in order to understand "why" AIIDC crashed because since i used only wide and medium it was not so evident that the cause was the spacing.
I must have been asleep the day I wrote that code ( i haven't take more than 2 days off in a row since January). It just was badly logic flawed, sorry about that.
Now I'm trying to understand why after stacking sometimes i get multiple (perhaps 4) small replicas of the planet in the upper side (visible only with huge level stretching) but it is a different story.
Are they the same size as the original or something else?
by the way... very nice NGC6995! Difficult task to get such filaments.
Thanks. I was surprised how well that worked out. I hope to shoot the west side of the veil if the weather cooperates.
A question: the stars are a little enlarged. Is it caused by the processing (level stretching) or they were big even on the single frames?
It's a couple of things. Turbulence was not real good and my stars have a FWHM of 3.5 to 5.5 pixels, which is about 2 to 3 times what most people get to the south of me in the USA.To get enough signal above the excessive light pollution, I Bin 2x2 stacked the LRGB movies too, which also remove the background and boosts the contrast And I did stretch the image in Astro IIDC too.
TTYL..
