SET-TEMP in FITS Header is missing

Thanks.
Another question: It would be very helpful for image registration in MaxImDL to set a filter name into the fits header if I don‘t use a filter wheel but your manual filter drawer instead. Currently I use L-Pro and L-eXtreme Filters with my ASI533MC-Pro
Thanks

PMTeam@ZWO

AstroVis Yep, got you and we are discussing supporting the Manual Filter settings under the EFW Settings page.

Thanks, I have installed 2.0 now, seem to work as before. But SET-TEMP and manual filter setting not yet available. Hopefully soon.

Thanks, I have installed 2.0 now, seem to work fine as 1.9 before. But SET-TEMP and manual filter setting still not yet available. Hopefully soon in the next update?
Thanks

AstroVis Got you and the request has been added to the todos.

Today I tried DSO Stacking with Bias, Darks, Flats and Lights. It cannot be used because satellite trails are not removed . What is wrong? Lights captured with ASI533MC-P

PMTeam@ZWO

AstroVis Thanks for your feedback, if possible, please share your fits files thru google drive or dropbox. So we can test and optimize the stacking result.

@ASIAIR@ZWO#59629 So we can test and optimize the stacking result.

When you stack images, you need to remove pixels that are outside the statistical noise from the camera and sky background.

See "Sigma Clipping" that is used by other programs (when there are enough subframes). The algorithm can be found here:

https://www.gnu.org/software/gnuastro/manual/html_node/Sigma-clipping.html

A bright pixel from a strong satellite trail that only appears in a single sub-frame is easily removed this way.

Hi, Thanks,
stacking with original files by MaxImDL is no problem. For stacking with Asiair, how can I remove invalid pixels? If SigmaClipping is not possible, than stacking with Asiair makes no sense. Of course I will not delete my files with satellite tracks for stacking, I would loose a lot of imaging time. If there is no solution in Asiair in the future, I will keep working with MaxIm DL. Not only the satellite trails but also the Fits colors are strange.

Colorproblems can more or less be solved with ColorCalibration, but with these Satellite Trails images are not usable.

AstroVis

OK, here they are. All Bias, Darks, Flats, Lights of Stock23 and Masterfiles

Hi,
good news. After stacking more files (now 51) all Satellite Trails disappeared.

AstroVis

Please solve my problems with missing SET-TEMP in Fits Header and Filtername for manual filter drawer, thanks

AstroVis Already in the todos. Thanks for your info.
