Celestron Power Tank 17 - Astroniklas

Maintaining batteries can be tricky if the weather doesn’t permit us from practicing our hobby over extended periods of time. 2021 was an exceptionally bad year for astronomy. Wildfires, wet winter with lots of precipitation and snow in the mountains. Unfortunately deep cycle batteries need to be taken care of and not allow them discharge below 20% of their capacity. It should be enough letting them charge over a couple of hours once a month. Unfortunately, just like many other users, I forgot to follow that routine, ending up with a dead battery. The replacement process is easy when you follow this YouTube guide below from another fellow astronomer.

I ended up buying the Duracell (DURDC12-20NB) battery instead which made it of course an upgrade.

The fascination of star gazing had already started during the very first years of my childhood. I was looking up at the night sky with my grandfather every summer night, studying constellations, the phases of the moon cycle, counting satellite passages and by using his binoculars to discover globular clusters of stars. Equipped with star maps from his home-library I was gradually discovering more and more of this fascinating world we call universe.
Even though years went by, the interest and fascination of cosmos had never left me… I found myself occupied with many other things before astronomy finally became my main hobby in recent years.

I was born in Stockholm, Sweden 1979 and grew for the most part of my childhood years in Greece. Later I’ve studied physics at Lund’s university and was hoping to continue with astronomy. At my free time I was an active amateur astronomer in South Sweden, Lund. At some point I was also appointed as chief of observatory for the Tycho Brahe Astronomy Society in Lund.

Circumstances in life led me to move with my family to California. Today I’m working as a sofrware developer within the aviation industry and weather systems for airports. During my off-time, I spend most of my time with my wife Melissa and our daughters.

My main hobbies are astronomy, astrophotography, game development and I was also a member of several astronomy societies in south Sweden but time was never enough to continue being an active member.

This blog is dedicated to my family (Melissa, Vanita and Lena Grace), our friends and to all of you who share the same fascination towards the beauty of this science and all the mysteries yet to be revealed by our constant discoveries!
