Good night,
I've been using APP flawlessly during several years. Right now I have upgrade to an ASI294MM and I'm finding that my images show some strange stacking patterns (vertical lines). No sign of this patterns on: BIAS (0,1"), FLATS (0,2"), DARKS (120"), BAD PIXEL MAP. So I guess it could be APP that introduces it...
Here there is a sample image on M13 region to see it: Single 120" Luminance (Baader filter 31mm) 120Gain_30Offset image:
@aleix To me these look like hot pixels that have been shifted a bit during the night. Are you sure that your darks are good so that APP can get rid of the hot pixels?
Thanks @wvreeven for your quick reply. I just started a new serie of darks and bias to see if the problem comes from there. I'll keep you updated.
Could it be related because I left all at deffault mode? I did not adjust any clipping settings.
Thanks again,
Aleix
@aleix Can you upload some lights and some calibration data to
https://upload.astropixelprocessor.com
using upload3 for both username and password? Create a folder aleix_hot_pixels and put the data in there. Then we can have a look and try to help you. Thanks!
With CMOS camera you should avoid taking bias: instead, it's mandatory to take dark-flats.
Then you should take flats with longer exposure, to say at least above 1 sec, better from 2 sec.
Thanks. I'll try that as well. My flats are 0,5" in average... Should I capture 2"?? Not the exact amount of time?
Never had this problem with my old ASI1600MM. Worked with BIAS along 4 years (maybe I had issues that were not that bad).
Thanks again.
I usually take my flats with 2 second exposure if i use l-pro filter; 3 second with l-extreme. Unity gain. 50 in total.
I'm using a cheap Lacerta led panel with dimmable light so that I can adjust light to match exactly above exposures depending on filter used.

@aleix Thanks a lot. In tab 2 at the bottom in the Cosmic Correction section I enabled "hot pixel kappa" and left it to 3.0 and then the hot pixels disappeared. Please give that a try and lower it to 2.5 if 3.0 doesn't work for you.

Many thanks. Right now just trying this setting. I'll update soon.
Thanks and best wishes,
