Re: Star colors

Gary,

For colour in the G17 or G18, I have to run my conversion program. That's no problem. Yes maybe a good idea to make special versions. The database size will increase with 20% but that's not a problem. I will do that in a few weeks.

Clear skies, Han

ASTAP 0.9.124, super fast stacking

The image stacking process in ASTAP 0.9.124 is about 8 times faster !!!

Reading a windows setting in a loop slowed down the process significantly . By keeping then in a boolean resulted in a great improvement in stacking speed.

Clear skies,
Han

Re: Points when adding R, G, B frames.

As an experiment, I tried above. The HFD results are worse. I assume the problem is that you start to spread the star flux. A star of one pixel could be spread on four pixels making the image less sharp. Nevertheless, By doing so, I found a way to make the stacking process MUCH faster. Will release ...

Re: Points when adding R, G, B frames.

Han, the dots are much smaller than they were. Can you add a separate addition option with sub-pixel precision? With the ability to select the number of sub-pixels. Hello Serg, Can you explain more in detail your request?. At the moment the stacking is pixel based. So the x,y position is calculated...

Re: Points when adding R, G, B frames.

Hello Serg, Strange, I tought it was okay. Maybe it was the handling of the pedestal factor for the red/blue pixels. Anyhow I made some more improvements this morning. This will be version 0.9.123 and released in an hour maybe. If I add the three stacked colors you send me, I get now this: Han serg_...

Re: Points when adding R, G, B frames.

Hello Serg, Problem solved in version 0.9.122. The blue spots where the summation of two pixels at one reference location. If you rotate one image (blue) sometimes two pixels fit in the diagonal length of one reference pixel. I count now number of pixels values added and also added a black spot rout...

Re: Points when adding R, G, B frames.

Hello Serg,

Thanks for the images. Blue it the problem. Blue is also rotated compared with red and green. Interesting test case. I will work on a solution.

Regards, Han
