Year End ARISS SSTV Event ISS Expedition 66

Still 2 days to go to download SSTV images send by ISS expedition 66. All images are related to historical lunar missions. So far I received 7 out of 12 images of which have poor quality. I'm using the WebSDR from Nurnberg. Nürnberg - Empfang aus 70m Höhe | WebSDR N (nbgsdr.ddns.net)

Mercury Transit May 9 2016 with ASI224MC and PIPP

I was cleaning up my astrodata and found some AVI-movies from the Mercury Transit of May 9, 2016. Some editing was done but always without a good result. Today I installed PIPP software (Planetary Imaging PreProcessor) to rework the AVI-movies (setting : Solar Close Up and AFB/AOI square on the solar edge). Next I used Autostakkert! 2.6.8 to stack the images (setting : Planets, max. treshhold and all "edge" boxes selected). The images are edited using CS4 and DeNoise AI. And the result... awesome.

Comet C/2021 A1 (Leonard) using new APP 1.083 beta3

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
