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:

Astroart 8.0 contains four new script commands which are used with the Apply Script Window. ApplyScript.First ApplyScript.Last ApplyScript.Index ApplyScript.Count For example, try the following simple script: Print Image.Background On a single image, it will print the background of the image. When u...

Hi, "-1.00 -1.00" is returned by the Telescope.List(..) when the index is out of bounds. The lower bound is 1, the upper bound is the number of objects which can be found with the function Telescope.List.Count.

On the same image if I give the center search region of 12 +46 (note that M51 is really at 13 30 +47 12) it also solves "successfully" (no error message). Hi, a tolerance of +- 50% with only 5 stars may cause false positives. I suggest to reset the tolerance to the default value of +- 20%. Actually...

Hi, Astroart plate solving does not use any external star catalog.
UCAC, GAIA, etc. are just for displaying stars in the atlas, changing them will not affect plate solving.
Regards, Fabio.

Hi, the option "Stars PSNR" should work too, and it's easier because there's no need to know the background in advance. To use Preprocessing to just analyze the background or other properties of the sequence, don't enable auto-alignment. Another long-term solution is to just delete the bad images. U...

It would be useful to take a look at all files of preprocessing.

Hi, the dynamic range of the image is too small (423..450, only 27 steps!).
You may solve converting the image to floating point before applying the filter (the preview is in floating point).
Or, to continue working with integer numbers, you may multiply the image by 10 or more.

Hi, the field of view and pixel scale in the "Options / Observer" is not used for plate solve, it's used only for the "Follow minor plate" alignment and the "CCD frame" in the Star Atlas. So, to change the settings for plate solve, just load the settings there and remember to click the button "Save ...

Hi, the image is 16 bits (range = 4 .. 53459) so it can be visualized in several ways. I think that you can emulate the visualization of Microsoft Photo pressing SHIFT + F3, which sets the 0 .. 65535 visualization. Or press the mouse wheel, then rotate it to adjust the black level in real time. Or u...

Hi Morten, at first I suggest to decide which will be the resolution of the final image. That will indicate which image will remain unprocessed and which one will be scaled. As you wrote it's also possible to use the comand Coregister, this will work well. If the difference in scale is not very high...
