Hi DerPit and thanks for your report and your efforts
Would you mind telling me what system you tried ALS on ?
We'll find a fix

Thanks again

Sorry for not stating explicitly. As in the signature, this is an openSUSE Tumbleweed (rolling release, so quite recent packages of everything).
I can also open a ticket in you issue tracker, if you prefer that.

Yes, please. A ticket would be great
Thanks in advance

Some news : ALS v0.7-alpha2 is out !

Just needs a few little cleanups before an official v0.7 release.

What's new since we last spoke :

• switchable night mode
• switchable 'save on stop' mode
• allow manual choice of Bayer pattern for demosaicing
• Various eye candy and stability stuff

This was made possible by the feedback you guys gave us. This is MUCH appreciated

Test away => als-app.org/assets/releases/v0.7-alpha2/

Thanks again and clear skies to all

Hello et Bonsoi,

before ALS I used AstroToaster based on Deep Sky Stacker Enginge.

ALS is now my choice, but I miss Kappa-Sigma Clipping for an even better result / for filtering out planes, and an automated restart of stacking if slewing to a new target.

Are there any plans for that?

Greetings
Steven

hi and thanks for the feedback

Filtering outliers would indeed be very usefull. We'd need to check its impact on performance.
Regarding auto-restart : as ALS is not connected to the mount (and won't be in a near future) we would need to rely on repeated alignment failures to assume user slewed to a new target. Would be worth a test.

Please fee free to create feature requests as issues on ALS's repo at github.com/gehelem/als .Who knows, we might find some time or horsepower to put them into ALS

cheers

Hi there - really enjoying this program and hope it will continue to develop! I'm finding tho that I would like to apply flats to my stacked images to remove donuts etc.  Any thoughts on how I can do this prior to the file hitting the scan folder? I thought to use a script like the one below but it's not working as expected. Before I spend a ton of time and effort debugging it are there any other alternatives?

workpath="./caliwork/"
calipath="./calibrate/"
rawpath="./raw/"
scanpath="./scan/"

var = 1
while var == 1: 
  list_of_files=os.listdir(rawpath)
  if len(list_of_files) == 0:
    time.sleep(1)
  else:
    imagefile = list_of_files[0]
    print("Processing "+imagefile)

    # Move the file to the work folder
    shutil.move(rawpath+imagefile,workpath)
    imagedata = ccdproc.fits_ccddata_reader(workpath+imagefile, unit='adu')
    masterflat = ccdproc.fits_ccddata_reader(calipath+"flat.fits", unit='adu')
    imagedata = ccdproc.flat_correct(imagedata, masterflat)

    # Write out calibrated result to the ALS scanpath for stacking
    hdu = fits.PrimaryHDU(data=imagedata)
    hdu.writeto(scanpath+imagefile, overwrite=True)
