Hot pixel disaster

I get some data from a friend to edit.

Messing around with BPM for days now, but still no success. 
All calibration frames loaded as usual.

Try to load or create a new BPM without any effect.
Check some Cosmetic Correction values under 2) CALIBRATE

Camera is QHY268C-PH and my APP version is 1.083
Solve the hot pixels in the narrowband pics, but not in the lights.

Any idea to solve the problem?

Cheers

Norbert

@norbert-a Hi Norbert,

Can you give us more info please? How many lights do you have? What calibration data exactly (any bias, dark, flat, darkflat)? Are all RGB or all mono files or do you mix them? What Cosmetic Correction values did you check? Are you using 1.083 or 1.083-4 (Windows) or 1.083-2 (Linux/Mac)?

 

Thanks, Wouter

Hi Wouter,

Thanks for your participation.

I get 8x900 sec. frames narrowband 

3x300 sec. and 4x900 sec. RGB lights 

plus master files: MasterBias, MD, MDF, MF and BPM.

All from the color camera QHY268C-PH.

I try different values from 5 to 12 in Cosmetic Correction.

I use the Windows version APP 1.083

 

Best regards

Norbert

@norbert-a Please use version 1.083-4 for Windows since 1.083 has several issues that were resolved in 1.084-4.

Are you using a single MF for both the RGB and narrowband images? If yes then that will not work. Also, are the MB and MD produced by APP? If not then that will not work either. You'll need to create all masters with APP.

Thanks for the hints.
I will update to 1.083-4 and check the RGB-MF.
I will report back to you on that.
Yes all calibration frames are produced by APP.

Hi Wouter,

Sorry for messing around.
We made new calibration frames and the hotpixel are gone.
So we can go on.

Best regards

Norbert
