Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
I am after some sound advice on what I am doing wrong with my DSLR calibration frames. I have used dark frames with the same ISO and exposure length (temp very close), flats the same ISO with histogram peak between 1/3 to 1/2, a master bias of same ISO and I still have these dots on my integrations. Looking into the lens on my scope I can see these dots on it, I believe they are dried droplets where dust has settled. I thought my flats would correct these? Is anyone kind enough to advise me on what I am doing wrong? I have so much good data that I want to process however I just can't seem to get rid of these dots.
Here is a link to the integration result https://1drv.ms/u/s!AizlV9aqtkAaoXjT0_dclAp4Q6x3?e=aqDreL
Thank you so much in advance!

Hi Daniel,
So would you be able to clean the optics? That will help a bit already. Flats also should reduce this and it looks like they weren’t actually applied or something with the flats data is not right still. You can see if it is applied by loading a single light frame and your masterflat. On top of the screen you select “l-calibrated” and APP should correct the light with the flat. It also shows up in the list below, your light frame will have the flat tag added to it. Do you see an effect?
@vincent-mod you are right for some reason the flats were not being applied. After deleting the masters and re calibrating, everything works as expected again. Thanks again Vincent, and yes I have also since cleaned the optics 😆
