Re: Problems with RAW files on OS X

For the CR2 files the pattern is RG = RGGB. Yes they are pretty green which many people have. The white balance is not correct. You can fix that for the viewer by going to tab pixelmath 1, go to topic colour correction, press auto and press apply. During stacking the colours ares corrected automatic...

ASTAP version 0.9.306 contains bug in average stacking

Unfortunately in ASTAP version 0.9.306 a severe bug was introduced in average stacking. This resulted in unreadable FITS files. (One line of code line was deleted by mistake) If you have this version, download 0.9.307. Version 0.9.306 was available between 2019-12-16 and 2019-12-18. Solving and othe...

Re: Image with range 0 1

I was a good exercise and allowed me to detect a bug in version 0.9.306 (wrong file format average stacking) due to a deleted code line. So get version 0.9.397. For de-mosaic algorithm, the advice is method "Astro-C, colour for saturated stars. Range 0-4095 (12 bit)". I was incorrect with 0 -16383 (...

Re: Image with range 0 1

It is fixed in the Windows and Linux version. Are you running MacOS? After stacking go to pixelmath1 and use auto correct colour. Press Auto, Press apply. Next time try let the de-mosaic be done in ASTAP. There this colour correction can be set automatically in tab STACK METHOD, section Raw one shot...

Re: Image with range 0 1

I have the images and can reproduce the problem. Will try to fix it.

I noted that images are already in colour= demosaiced. For a better star colour you better leave them raw next time.

12 bit FITS files don't exist. It is either 8, 16, 32 or 64 bit. So for 12 bit DSLR image use 16 bit file format.

Re: Image with range 0 1

Below a quote from the INDI forum describing how to switch to 16 bit. I haven't tested 8 bit stacking for at least 18 months since it is very very rare. It is very possible it goes wrong due to the 8 bit. So the advice is to create 16 bit images. I will do some testing with artificial 8 bit images. ...

Re: Image with range 0 1

Any idea if you can set in INDI 16 bit instead of 8 bit? Camera driver?

Re: Image with range 0 1

The 8 bit image is strange. Normally it should be a 16 bit image. A DSLR is at least 12 bit so 8 bit is compromising the quality. I can see it is written by INDI (Ekos?) Could you provide me with one (or more) images created by Ekos for testing. Upload it somewhere and give me the link. Clear skies,...

Re: Bug, feature request and performance

I think I fixed the first error. There was an menu option shift+H. This is now replaced by ctr+alt+H

Re: Bug, feature request and performance

Hello, see answers below. Han Hi, thank you for a great tool. Trying it out with some narrowband images, I came across the following challenges: 1. Bug. In the stack method tab, I cannot enter "Ha" into the filter box; only "ha" works. The tool sometimes crashes when entering capital letters. I will...
