Re: Astroart 8 SP4
further information from the updated documentation: Optical distortions with user defined polynomial order ... use the option "Distortions between images" only if the images cannot be aligned well by normal rotations. This can happen with large fields when the images were taken on different nights o...

Re: Full Frame Focus Exposure Time By Filter
Hi Joe,
you may switch to SP2 / SP3 , using the SP3 Upgrade: https://www.msb-astroart.com/down_en.htm
but I think that nothing will change.
Maybe you are now using the 64 bit version? Maybe you upgraded the QHY ASCOM driver and now the device names are called: QHYCCD-Camera and QHYCCD-Guider?

Re: Starnet path
The setting is saved into the "Temp" folder of Windows, so it's possible that if you "clean up" the PC it gets deleted too.
In a future release it will be saved into a more persistent folder.

Re: Full Frame Focus Exposure Time By Filter
ASCOM relay boxes are rare hardware which converts USB/serial to an autoguide cable, it's probably not the correct settings. If there is no need to control the mount for GOTOs, I confirm that the correct setting is: "Camera 2 relays" / "Same connection of GOTO" or "ASCOM guider relays" / "Same conne...

Re: Full Frame Focus Exposure Time By Filter
... Looking at the full frame focusing window in AA8 there isn’t an option to set the exposure duration by filter (I.e. 3 seconds for LRGB filters and 30 seconds for the narrow band filters ... Until now it's only possible with scripts, but that's actually an interesting feature. It will be added t...

Re: RGB brightness cataloque
Hello, do you refer to the smaller catalog of 1346 stars or the bigger one with 15 millions stars ? At the moment other catalogs cannot be added to the Star Atlas, but these two catalogs could be accessed by an image processing plugin, for example to create a synthetic image, a reference to calibrat...

Re: Time stamp for recorded airmass
Hello, the airmass is calculated at mid-exposure.
Instead, DATE-OBS is always the start of exposure in the FITS standard, and mid-exposure is a calculated field, as: DATE-OBS + EXPOSURE/2.

Re: Vanderbei Deconvolution for coma and field curvature.
That's interesting. Yes, that plug-in is single-threaded. It looks like most of the blurring is caused by image deformations from different wavelengths, not PSF. Maybe after having separated the image into R-G-B channel the new alignment with distortions could attenuate the problem (align R to G, th...

Re: DDP star bloat
Hi, it's not easy to reply without seeing the actual image. By the way, you could use the StarNet plugin to apply DDP only on the nebula and not on the stars: 1) Duplicate the image, let's call it "B". 2) Apply your DDP on image "A". 3) Apply a DDP with low gamma and mid white point to image "B" (so...
