Re: AA8 SPk Telescope Control - Centering

Hello, 1-2) It's required to click "Save parameters" in the Plate Solve window. This does not depend on Service Packs, it was required also in Astroart 7 for centering the telescope with plate solve. So, 13.5 +- 10% arcminutes is probably the default settings for plate solving. Changing them without...

Updated DSLR plugins

Hi, the plugins for controlling Canon and Nikon cameras have been updated to support the latest cameras.
See: https://www.msb-astroart.com/ or
https://www.msbsoftware.it/astroart/
If you are already controlling a supported camera, there is no need to upgrade.
Clear skies, Fabio.

Re: Making photometry measurements in AA8 (and do a AAVSO file)

At the end of batch photometry, you could set a format something like: RR LYR,<JD>,<MAG1>,<MAGERR1>,V,NO,STD,NA,NA,NA,NA,<AIRMASS>,NA,[ChartID],NA to create an AAVSO report in magnitudes, but this would be only the last step of a more complex procedure. Star detecting can be changed from Options / S...

Re: Plugin development - RGB picture

Hi Nuno, OK, meanwhile a faster script can be obtained using a Formula: Image.PrepareUndo f = "vr : If(0.5*(vr+vb)<vg, 0.5*(vr+vb), vg) : vb" Image.Formula(f) Image.Update It will be faster than a script code, but still slower than a real plugin. The same formula can be used to create a direct comma...

Re: How sum an H-alpa session and RGB

Good morning, if the H-Alpha is to be used as luminance, then the command is: LRGB Combine.
If not, probably the H-Alpha should be normalized to the color image (Arithmetic / Normalize / Scale) before proceeding with other commands.

Re: Can't open image stacked with Pix Insight

The dynamic range of that FITS is floating point 0.0 - 1.0, if you need to recover the ADUs you could multiply the image it by 65536. Was this the problem ? If instead the problem was to change the visualization, then try: CTRL + Wheel rotate for finer control (CTRL + SHIFT + Wheel for the black lev...

Re: Open .avi file from ASI-183+ASI Studio.

Hello, I was able to open the video on one PC but not on another one. The Windows API function: AVIStreamGetFrameOpen() returned NULL which means missing codec. The format is indeed peculiar: a color video plus a grayscale palette. Windows Media Player can play the video on both PCs. VLC showed it c...
