I have a Vaonis Vespera Pro.

I attempted my first stack with APP and failed at the integration stage.  I received three consecutive error messages all referrring to insufficient RAM.  I have 32 GB of RAM which I know ordinarily to be enough.  I tried reducing the scale right down but this did not solve the issue.  After the third error message there is a bell sound and the integration fails.  

I then checked the FOV size and it was utterly ginormous, millions x millions, clearly hence the problem.

I then changed to a completely diffrent data set for a different target.  This time the FOV size was 10000 x 11000 and would have needed 805 GB of hard disk space to integrate.

I seem to have a problem with the FOV size post Registration.

Can somebody please help as I cannot get beyond registration currently due to the FOV size.

Thank you

I've managed to load the frames, set the "save directory" to a folder on my desktop, registered them, then APP makes the "gong" sound but no image shows in APP or is saved to the folder I set the save directory to. Where is the stacked/registered image? I've looked through a few tutorials but I think this question is so basic no one covers it. Thx for your help.

The attached stacked image is produced by stacking 60 frames with dark, bias and flat using an ASI 2600MC and Celestron edge 11". As you can see the image is dominated by an intense green color difficult rot remove in post processing. If I check the "neutralize background box , the background turns red. Can you please help?

You should have the option to save the entire integration skeleton of the different sessions so that even if the APP is closed, only one can reopen it and everything is ready to reintegrate. I hope this option is taken into account.

I think this also requires the star shape and quality metrics to be adjusted accordingly.

I keep getting the following error when I batch crop images; typically they are normalized Broadband (OSC) and Narrowband (dual NB) Fit files. This started to occur at beta44 (wasn't a problem before) and it is still there in beta45. It occurs NOT during the crop but during the save... Here is the error in beta44:

Please note, however, that as far as I can tell, the crops appear to have been successful.

Here is the log portion (I added the "arrows"):

For me, this behavior originated after an update from beta 41 to 45 in windows11.

The available workarounds are to set the save directories before loading any files or not attempt to set a save directory and allow files to be saved to the Work directory.

IMHO, the new naming of Normalize modes is a bit confusing/counterintuitive...

"overlap area" - would be good for mosaics since the panels usually overlap 10-20%
"full image" - would be good for regular integrations where panels fully overlap

But, regardless, currently the default mode is "full image" which is supposed to be for mosaics.
Please change the default to "overlap area".

Or I am wrong?

Thanks!

Max

Seem's running but nothing happens.

The JDK process is running.

Rolling back to beta44 works well.

Do you know the issue?
