Since december 22, 2021 the new beta 3 (almost stable) version of APP 1.083 is available. Previous beta2 version did not always allowed to select the nucleus of the comet. With this new beta3 version no issues were found when selecting the comet's nucleus. Great work to the Aries Production team!
I reworked my pictures of the Comet C/2021 A1 (Leonard) taken on december 8th with following setting :
- Nikon D7500 and TLAPO80/480 f/6
- lights ISO1600 and 32x30s
- darks, bias, flats and dark flats
- stacking using APP and final editing with CS4 & DeNoise AI
