Celestron Power Tank 17

Posted on Updated on

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.

Time for Jupiter again

Finally! The weather allowed me to bring out my telescope. It was about time to run some tests with my Celestron NexImage camera. There were many attempts trying to adjust several parameters such as brightness versus contrast, frame rates, quality, shutter speed and so on. I finally found out what to do and was able to record a short movie of Jupiter and then process it in RegiStax 5.

Programs used:

  • RegiStax 5.0
  • Celestron AMCap
  • Adobe Photoshop CS2

The trick is to capture a planet by recording an AVI-movie, process it through Registax, do final adjustments in Photoshop and voila!

Last night I finally received my Celestron cam! After some adventures between Amazon.com, my bank and VISA, because of warranty & delivering issues towards me as a European customer it’s finally in my hands. I’m eager to start working with this camera as soon as possible whenever weather circumstances allow me.

The installation worked smoothly on my Windows XP service pack 3 for both my PC and the laptop. This cam is used to record a planetary object such the sun, moon or the planets. The software that follows with the camera assists you to filter out blured and badly exposed images due to atmospheric conditions. I’m giving you a couple of examples on the results below.
