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.

Hello Admin,

I have used a Bad pixel map for my DSLR as a super calibration frame. I made it around a year ago by integrating approx 8 hours of 5min subs at room temperature. It still works great. and since then I never used dark frames. Only BMP, Flats, and Master Bias.

Recently, I have switched to ASI 1600MM GT (mono) camera. I want to know if making BPM for a cooled mono cam works as it worked for my DSLR. What would be the best way to make it if it works and provides an advantage (along with the dark frames library)? Do i need to use master dark too?

Is the BPM sensor temperature dependent? if yes, then which temperature should I choose? I usually image at -10 degree C sensor temperature. Should I make it at ambient temperature without cooling? and the same for Flat frames (Temperature, filter, etc) 

I really appreciate any help you can provide.

The BPM is independent of camera settings, including temperature. It's a map of the characteristics of your sensor and the best way to create a good one is to use a few long, uncooled darks. You can indeed just use a BPM, but only if you don't have amp-glow. If you have amp-glow, darks are still vital.

Thanks for the reply. Yes, my camers has amp glow so i would definitely need master dark. But i would make a Good BPM by shooting darks as worst as possible 😅😅 such as ambiannt temperature and high gain.

Thanks again
