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.

Hello everyone.

I have something wrong with the flats in the calibration process.
I use Flats, Master Dark and MasterFlat for calibration.

Because it doesn't do what I want properly, or I'm just a bit stupid to understand it correctly

here the comparison of the only strached output pictures

  • first:

without APP - nice flatted

Cal+Stack by DSS, some streched & Color balamced by PS

  • Kal + Stack DSS   strech + just PS

  • second:

with APP - only pollution gradients?

cal by DSS, then integrate wirh calibrated Lights only


  • third ---> MY PROBLEM:

only used APP (cal, stack, normalized, integrated, streched) - strong vignetting? 

  • M 52 46fr lpro LPro session 1 nur mit APP


 

and the Flat:

MasterFlat Gain90

 

I dont removed any gradiends

 

It is made up of 43 x 300s. RGB frames (ASI071MC Pro) Gain 90, Offset 65, -15°C near fullmoon

I left all settings at default

 

Maybe someone will recognize what I'm doing wrong

 

Thanks a lot 🙂

Difficult to tell as I don't know DSS myself. I can check the data to see what's going on if you want, if so, please upload like 10 lights, 10 darks, 10 flats, 10 bias (or darkflats) to our server (please use the login and password provided below):
