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.

Stacking without Dark Frames? Possible?

Hello Guys,

I am a DSLR user and sometimes i dont take dark frames but dither after couple of frames. Till now i have never faced any problem in DSS. I am not sure if APP allows stacking without Dark frames or not. Anyone can help me out?

It allows for not using any calibration frame, but I'd highly recommend using darks as it will help your data. You don't have to create them every session, just one or twice a year depending a bit on outside temperatures. If you don't want to use them, you can also create a very noisy (long exposure) dark and create a Bad Pixel Map from that, a BPM can be used for a very long time with all your data.

@vincent-mod thanks for the reply. I usually try to take atleast 15 or 20 darks depending how long my subs are and how much temp fluctuations occurs throughout the night. But sometimes i feel lazy to take.🤣

One more question, everytime A BPM is created. How to use it? When to use it? Can it be used with any future stacks no matter what was the exposure time; ISO etc?

Can i make a BPM with a 10min dark and flats at particular ISO (lets say ISO 800), and use it later with any other stackings?

 

TIA

Yes a BPM can be used with whatever data you have. You can take your worst darks and create a BPM with that, save it somewhere and re-use it every time. I would once in a while have a good check to see how well it still performs on the pixel level, but you can usually use it for a year or more (depending on your sensor's characteristics over time). I do tend to still use darks together with it, but if you have no amp-glow you can use just a BPM.

@vincent-mod it means! By making a Good Bad Pixel map, i can use BPM, Master Bias And Flats, together with light, right?
