Re: GAIA2 Catalogue
Hello, GAIA star names are so long (example: 3510125382014416256) that are usually not included in compressed catalogs. Actually it's shorter to use coordinates as a reminder, eg. 231559.3+225612. In Astroart I suggest to use a Bookmark (right click in the atlas). The 300 most brighter stars can be ...

Updated ASCOM plugin
Hello everybody, at the Astroart web site: https://www.msb-astroart.com/ it's available an updated plugin for ASCOM cameras (version 2.60). One option has been added: "Timeout for ImageReady", in seconds. There are indeed some ASCOM cameras that wait for infinite time in case of a download error (if...

Re: Flats strange display
Hi, 1) I didn't understand well the problem, but the fastest way to restore a visualization is clicking the Status Bar of the image (the one which shows R = ... B = ... V = ...) or pressing F4. 2) The two visualizations are different, the first is V = 22434 .. 22434, and there are no pixels brighter...

Re: calibration frame
Hi Morten, to view and save the master dark frame and flat field, enable the option "Show master ..." in Preprocessing. Actually to just create a master it's even simpler to use the Images box, so that you could add some other processing, for example you could correct the dark frames of the flat fie...

Re: Compare 16 vs. 32 Bit
Hi, to average (or sigma+average) a sequence of 16 bit images, consider the option "Keep result in 16 bits", since the flat field correction can indeed exceed the 16 bit range if a saturated star (65535) is present. To compare quickly the dynamic of several images, open the Statistics Window for one...

Re: Subframe From selection choice
Hi, the image with the rectange must be selected before clicking "From selection" otherwise nothing happens. To help, a notification about this will be added on the Status Bar of AA8 SP2.
Thanks, Fabio.
Thanks, Fabio.

Re: Trichromy for Ha, OIII and SII filters
Hi, in the Trichromy Window you may use the color matrix,
for example:
R -> 0.75 SII + 0.25 Ha + 0.00 OIII
etc.
for example:
R -> 0.75 SII + 0.25 Ha + 0.00 OIII
etc.

Peculiar flat fields for research
Hello, for a peculiar UBVRI research, the following specification were needed for flat fields: 1) Taken every night, on the sky, at sunset or dawn. 2) Taken for all filters (UBVRI) using an optimal exposure of 2/3 of dynamic range. The main problem was to find the correct exposure. It was solved tak...

Re: Astrometry in AA8
Hello, that quick conversion tool works correctly, but the X/Y coordinates at startup are indeed wrong: X is set to Height/2 and Y to Width/2, which should be flipped (it could be done manually if needed). It will be corrected in AA8 SP2. If you like to have the prerelease just write me by PM or ema...

Re: AA8 User manual
Hi, the demo version contains the manual in Help format (file: AA8_EN.chm), which can be read also without launching the software. The PDF version of it (the content is exactly the same) is instead included only in the full version of Astroart. Its format is optimized for tablets, see: https://www.m...

Re: Starnet v2 Call with Macro
An updated plugin for version 2.0 is available as well, so there's no longer need to rename the executable:
