Any experience by users with the above program from B. Franke? http://bf-astro.com/eXcalibrator/excalibrator.htm . It was recently reviewed in a german astronomy journal. It takes the plate solved image and determines the coefficients between the 3 color channels from the star colors in catalogs. It...

Very nice image. Amazing what is possible with those filters. Could you give a little bit more detail about the acquisition, equipment and processing?
Thanks in advance

Thanks for your reply.
I am doing flats again since some time, but have not done them for some time (my bad) and want to post-correct some of those images.
I will go with the rgb extraction

Maybe i am thinking backward, but can the following be done (easily) in AstroArt (or other software): I want to extract the 4 different color planes of the raw images (before registering and stacking) of a one-shot color camera. The Bayer matrix is: 1. row RG1RG1 and so on 2. row G2BG2B and so on I ...

LAA is the large memory access Version.
They all run very stable. What is the problem?

There are actually 3 versions of AstroArt, a 32-bit , a 64-bit and a "LAA" version.
Only the 32bit and the LAA version are showing the plugins (camera control etc).
The 64bit version is limited to image processing (see also in the help file).
I hope this helps

Thanks Fabio for the quick and comprehensive reply. I will focus on the respective dark frames first and also double check where I have “real” flats.

Thanks Fabio,
Looking forward to the fix.

I am taking images with a C11 Schmidt-Cassegrain in Hyperstar configuration. So, i do have quite some vignetting plus a relatively large central obstruction. When i try to correct the images for vignetting, i am ending up most of the time with a donut shaped background in the middle of my images. He...

When using the "Profile Mode", i am sometimes seeing a strange behavior when updating the profile: In Profile Mode, after drawing a line with the cursor across the whole image from upper left to lower right (example attached), Profile error 1.png when clicking "Change Profile", the profile resets to...

Fabio, thanks for your quick reaction. I agree, the added latency added by the ASCOM driver doesn't sound like a lot and is not bad, BUT if the native driver downloads up to 6fps full frame in 1x1, it is still more than an order of magnitude slower. Yes, the QHY268C and the corresponding ASI ZWO 260...
