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.

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.

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...

An updated plugin for version 2.0 is available as well, so there's no longer need to rename the executable:
