Moon Halo

 

An 360° halo around the moon. Picture taken with Nikon D7500 10mm f/3.5.

Sun in H-Alpha

 

It was a sunny day with high clouds and around 0°C. I was not able to make some flats and therefor it's not a great picture but still ... a couple of huge prominences and filaments.

Exposure : 1000 frames @ 81,86fps or 5.08ms using SSD, binning 1x1

Horsehead and Flame Nebula

Picture taken on wednesday January 10, 2024 of both Flame (NGC2024) and Horsehead Nebulae (IC434) in constellation Orion. Conditions were good with temperatures between -4.5°C en -6.5°C. This was my first DSO session since June last year. It was also my first DSO session using the Optolong L-Pro filter. It took me more then a hour from installing the mount to taken my first photo. This is beyond the fact that the day before the entire set up was tested inside (dry run).
