Comet 2020 Neowise

Comet 2020 Neowise (aka C/2020 F3 NEOWISE) was easily visible in the evening in the Northern hemisphere during the July 19 week end. While the kids were doing a bonfire, I did some DSLR pictures, at 200mm of focal and f/2.8, without bothering with an equatorial mount (most of my time was spent supervising the bonfireContinue reading “Comet 2020 Neowise”

Damselflies

Damselfiles (demoiselles) are smaller than dragonflies, and when at rest, they fold their wings over their bodies, unlike dragonflies who spread them open and flat. I found a few of them while visiting a creek in East Texas and took some time to do some Macro pictures.

CTA 102 is a blazar-type quasar discovered in the early 1960s in the constellation Pegasus. It is also one of the two great false alarms in theContinue reading “Taking a picture of the most luminous blazar flare ever recorded.”

Colorizing old black and white pictures with deoldify

I was looking for a cool Machine Learning project, using Python, of course, and either PyTorch or Tensor Flow, since it’s what the cool kids are doing those days. I have also always had an interest in restoration of old pictures, and sometimes colorizing them, which is a very tedious & time consuming project ifContinue reading “Colorizing old black and white pictures with deoldify”
