Looking at cheap high resolution analogue cameras for video astronomy use

Analogue CCTV cameras designed for cheap and mass surveillance systems aren't very useful in astronomy due to very poor image quality aside of some top shelf or more modern cameras that are actually very good at video astronomy and similar usages. Going with the progress of technology we now have AHD cameras - analogue cameras with higher 720p or 1080p resolution. They cost only 7-15 USD but are they any good and how can we use them?

Lenses in DS astrophotography

Lenses in astrophotography have been bit forgotten in favour of big and shiny astrographs. With the introduction of latest CMOS based cameras with smaller pixels lenses become a very interesting and viable option for DS imaging at a low cost.

What are the lens options we have today and how can we connect them to our DS or planetary cameras?

Planetary cameras and equipment for 2016

Every year I try to summarise the hardware, camera market for Solar System imaging. This year I was holding this article back a bit to see what will happen with the new cooled ZWO cameras.

So what happened in 2015, and what interesting things await us in 2016? What are the best camera options?

Tutorial on how to play Abathur in Heroes of the Storm

Abathur, master of evolution and a specialist in Heroes of the Storm is one of the most unique heroes of HoTS or MOBA in general. His unique play style as well as multiple talent paths make him challenging yet very rewarding to play.

In this article I'll try to describe Abathur and his game play options.

Testing DDR3 and DDR4 RAM performance on Linux

RAM is one of essential computer components. It holds executed program, its data and result. From RAM availability and performance depends how your computer will perform in general.

With the launch of Intel Skylake CPUs a new generation of RAM was introduced to the mainstream - DDR4. So let us take a look on modern DDR3 and DDR4 performance.
