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 :)

Workshop Nightscapes
The next three weeks I will be attending the Workshop Nightscapes. This 3-day workshop is organized by Urania in Hove (Antwerp). The whole idea is to explain how to make astropictures using a DSLR camera with only use of a tripod. This interactive and practical workshop hopefully will provide some tips and tricks to make nice and easy nightscapes.
As a start focus was given on the concepts of ISO, Diaphragm (Aperture) and Shuttertime. At the end of the workshop a real hometask was given ... :)
