Comet Neowise C/2020 F3 reworked with APP betaversion 1.083 beta1



My pictures from last year of the bright comet Neowise C/2020 F3 are reworked using AstroPixelProcessor (APP) beta version 1.083 beta 1. With this version the option comet can be used under chapter 4 "register". There is also a way to clean the picture from startrails under chapter 6 "integrate" by choosing filter "MAD rejection" (and integrate mode avg or median) with kappa low (8) and high (2).  Last year I used DeepSkyStacker to stack the pictures.
