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.
I've had an issue with flats since late last year. Up until then, they were calibrating fine. I've never used dark flats as haven't needed to. I have tried them to calibrate the flats, but that didn't work either. Im not sure what's changed but it's driving me mad and has ruined a lot of imaging time. As you can see, it's highly typical, the bunnies are over the neb 🤦♀️I run the latest version of APP, I keep settings the same (obviously apart from exposure) as my lights. I try to match equal amount of flats to lights. When I load all my data in and click 'l-calibrated', the bunnies stay as they are. If its not a setting in APP (because I've changed nothing) perhaps a camera issue. Whatever it is, it's getting me down. I use an Altair 269c TEC. Captures and cools absolutely fine, so no issues there. I use SC for capture and histogram at 30%. Attached is one of my flats, baxkground neutralised, which I think looks fine. Looks like how a my others have previous to the issues. Need some other ideas if anyone has any please. Thank you
You don't need to keep the same setting as your lights for flats, offset I would keep the same, but iso/gain can be changed. For gain you can lower it to maximize the dynamic range of the sensor and then exposing the flats until the peak in the linear (!) histogram reaches about 50-80% of the range (30% is low and you seem to be clipping (maybe) on the left (best to check with stretching off), as long as it's not clipping on the right, you can expose for longer. Bias or darkflats that match the settings of the flats are then required, I'd advice darkflats as some sensors misbehave when taking the shortest amount of exposure for bias. About 20 flats is fine as well.
When you have the masterflat and masterdark you can load in a light, go to the preview filter (on top) and select "l-calibrated" to see if the flat is applied, you should then also see the tag "MF" in the filename for the light below in the list.
