UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

Good morning,

I'm using APP 1.075 beta4 to calibrate and integrate images taken on a Canon 5D MkIV DSLR and see this message during integration.

09:54:18 - 6) INTEGRATE: integrate light frames: wrote frame: 8 to file mapper
09:54:20 - GENERAL IMAGE LOADER: loading frame D:\Temp_workspace\200919 Veil Nebula\Lights\L__21B9042_ISO800_240s__24C.CR2
09:54:20 - 6) INTEGRATE: integrate light frames: loaded frame 9 of 36 frames
09:54:20 - GENERAL IMAGE LOADER: frame D:\Temp_workspace\200919 Veil Nebula\Lights\L__21B9041_ISO800_240s__24C.CR2 was loaded successfully
09:54:21 - 6) INTEGRATE: integrate light frames: LNC: got center coordinates and area of frame 9 in integration composition
09:54:22 - 2) CALIBRATE: Adaptive Data Pedestal: enabled
09:54:22 - 2) CALIBRATE: Adaptive Data Pedestal set at: 9.761E-03
09:54:22 - 2) CALIBRATE: WARNING !!! we have detected a possible sensor offset issue between the MasterBias and the Masterdark !
09:54:22 - 2) CALIBRATE: WARNING !!! the MasterBias has a median value of: 3.125E-02 for channel 1
09:54:22 - 2) CALIBRATE: WARNING !!! the MasterDark has a median value of: 3.112E-02 for channel 1
09:54:22 - 2) CALIBRATE: WARNING !!! normally, the median value of the MasterDark should be the same or larger than the median value of the MasterBias
09:54:22 - 2) CALIBRATE: WARNING !!! because a dark should always contain the entire bias signal plus the dark current and possible amp glow signals
09:54:22 - 2) CALIBRATE: WARNING !!! some CMOS sensors however exhibit this behaviour due to CMOS technology.

Details of the DSLR raw files are:

40 x 240 second Lights, 20 x Flats, 20 x  Darks, 50 x Bias. Everything was shot at iso800 and same sensor temperature

Anything I should be doing different during the calibration or is this message fairly typical?

best regards

Kev

Hello.

 

I have the same console message. 

 

MBP, OS Mojave

APP 1.075 beta4

Canon 60d, ISO 800

Lights 17x 360s

Darks 26x 360s

Bias 40x 1/125s

Flats 40x 1/13s

DarkFlats 40x 1/13s

 

What is wrong?

 

Best regards

Mariusz

Nothing, it is a warning, however the values are the same or very close to being the same. It shouldn't impact the result.

Thank you Vincent. I'll continue to ignore it 🙂
