Sun after snow

Yesterday it was snowing but this afternoon clear sky with a beautiful Sun and Sunspots. Meaning I'm installing my scope with Baader filter.

Nikon D7500 ISO Noise

Pictures taken with Nikon D7500 in RAW, with cap, shutter speed 10s and different ISO levels. With gamma levels put to the most extreem (to zero) we can see noise showing up as from ISO 6400. Also other reviews show noise coming up around ISO 6400.

Dynamic range drops significantly as from ISO 51200 but EV levels are below 6.  ISO 12800 has EV level 6.6 which is exactly 50% of the max. EV level (ISO50).

Falcon Heavy Launch

Wow, what an amazing launch test yesterday of the Space x F9H. On Tuesday, Feb. 6th at 9:45 PM, Falcon Heavy successfully lifted off from Launch Complex 39A at Kennedy Space Center in Florida. Falcon Heavy is the most powerful operational rocket in the world by a factor of two, with the ability to lift into orbit nearly 64 metric tons. To give you an idea : the rocket realized the speed of sound 1 minuut after lift off ... 

But for me the most impressive moment was for sure the landing of the two boosters, simultaneously, only 8 minutes after lift off. 

As I watched the launch together with 20 other classmates on a big screen in Antwerp, I realized everbody was clapping their hands once the boosters touched ground. So I was not the only one being impressed :)
