Image of Comet 12P/Pons-Brooks taken on Wednesday March 27. Some high clouds but still, when looking good you will recognize two tails.

Setting: Nikon D7500 f/5.6 200mm telelens, 39x2s on ISO12500. High ISO to prevent startrailing.
Stacking was done with APP 2.0.0 beta version 26. It took some time as settings were not correct.

Circumscribed Halo



At noon the Sun came out with a halo round it. Beside the 22° halo, there was also a circumscribed halo above the Sun and the parhelic circle. After editing the picture, I found also the lower circumscribed halo.
According Meteoros.de website  i could simulate my image.

Astrometrica Software

 

Yesterday I found out the existance of Astrometrica Software (thanks to Bert Moyaerts) and which can help identifying small objects. Astrometrica Software provides the ability to easily compare astromerical images for the purpose of moving object detection. See links below for software, installation guides, instructions, and practice image sets.
