Hello, if for this test the ASI290MINI is used as a main camera, then the relays to be selected in the Telescope Window is "Camera 1 relays" (or "ASCOM camera relays").

Hello, at the moment it's not possible, but it will be added to SP2, to be released this summer.
If you like to receive the prerelease, just write to me by email or PM-

Hi, here is an example, taken from: https://www.arciereceleste.it/tutorial-pixinsight/cat-tutorial-eng/85-enhance-galaxy-ha-eng 1) Subtract from the HAlpha a fraction of the continuous spectrum of the Red image: Merge.jpg e.g. select the HAlpha, click "Merge" from Arithmetic menu, select the Red, co...

Hi, in AA6 I suggest using a Macro instead. Using a script would be much more complicated. At first define the Macro, use the command "Define Macro": Define.jpg as a test, try the Macro manually on some images. Then this macro can be applied on several images on disk at once, command "Apply Macro" A...

About ILP files: ILP is a new open standard to make preprocessing files compatible between different software, see: https://www.astrophotography.app/ILP_Standard.php for the moment Astroart is only capable to read these files, but in the next version it will be also possible to write them. ILP permi...

Hello, a new minor version of Astroart 9 was released today. Actually this is the biggest upgrade ever released in a service pack. Download at: https://www.msb-astroart.com/ Version 9.0 SP1 - February 12, 2025 -------------------------------- * New feature. Filter for removing bright and dark spots....

Hello, an updated plugin for opening CR3 files from Canon cameras is available at the Astroart web site:

Clear skies, Fabio.

Hello! A different demo version, time-limited, where the star atlas is present is a good idea. However the star atlas cannot do much with the telescope. All the advanced functions are done outside the star atlas (plate solving, auto-centering, sequence of objects), so this will not solve the problem...

Thanks, in the incoming SP1 there will be two new filters to post-process uneven brightness. One is indeed for mosaics, to soften the edges, before a further background normalization. The other can be used for isolated bright and dark spots. Here is an animation about the first one: Fabio. EdgeAnima...

Yes, but I can add that option also to an experimental version of Astroart 8, it's easy to add.

Hi, in preprocessing, a GRGB RAW flat field (so grayscale) is used as luminance (unless it's already a color master flat field), so it cannot correct chroma variations. The menu command "Image / Divide" instead divides each R/G/B planes separately. To solve, prepare a color master flat field (averag...

There is no solution, a flat field can only correct vignetting and dust. To correct also light pollution it should be taken on the same zone at the same hour, but that would mean a different flat field for every object. Also light pollution "adds" light to the image, instead of "multiplying" like vi...
