Re: Evaluating Demo Version

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...

Re: M31 - 8 frame Mosaic; a work in progress!

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...

Re: Problems with Flat Field Correction for Color Camera

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

Re: Problems with Flat Field Correction for Color Camera

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...

Re: Problems with Flat Field Correction for Color Camera

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...

Re: Problems with Flat Field Correction for Color Camera

To solve it would be needed to see the original images. I think that Preprocessing is actually applying the flat, but the correction is partial because the images also have an extra gradient caused by light pollution.

Re: Problems with Flat Field Correction for Color Camera

Hi, the image "without flat processing" shows a strong left-to-right gradient, so that flat field cannot correct the image in any case. Maybe there was a strong light pollution or dew. Here is a quick processing on that JPEG with Remove Gradient Adaptive 25, after having masked the nebulas: RemoveGr...

Re: PB Temperatur ASi 174 Mc cool.

Hello, it's unlikely that the problem is caused by the .NET version, unless the camera worked perfectly before the automatic Windows update. Instead: are both PCs using the same ASI ASCOM driver? The latest version is 6.5.26, see: https://www.zwoastro.com/software/ to download the 32 bit version cli...

Re: AA9 feature request: auto target name from goto name

OK thanks, it will be added.
It will be released with SP1 in February. If you like to have the pre-release, just contact me by PM or email: https://www.msb-astroart.com/support.htm .

Re: Memory allocation per image

Hello, it's not possible to reduce the memory used, but you may use the LAA or the 64 bit version.
If the MiniPC has an SSD it will be very fast to use virtual memory on disk, even if the physical RAM is only 2 Gb.
