Celestial Videos

Astroscan TelescopeEvery year, I get an Amazon gift card from my mom for my birthday. This year, I used it (along with some of my own money) to buy the Celestron NexImage Solar System Imager - an attachment for a telescope that lets you digitally capture what you would normally see through the eyepiece. It also comes with software that lets you 'stack' frames from a recorded video, and then the software will clean that up to give you a good still image.

I took it out to play with for the first time last night. I still have a lot of learning left to do, but at least I could see on the monitor something resembling what I saw through the eyepiece. Just for the hell of it, I decided to post two of the videos I captured last night. The cool thing these videos show is just how fast the Earth is moving. I wasn't moving my telescope at all (except for the big jumps and the one change of focus). The motion of the objects across the frame is due solely to the Earth's rotation.

In case you haven't figured it out, what you're seeing in the two videos above is Jupiter and some of its moons. The second video is with the NexImage directly where the eyepiece would normally go. The first is with a 2x barlow lens. For reference, I'm using an Astroscan telescope (which explains the jumpy movement when I have to re-aim).

Like I said, I still have some learning to do. Those videos are definitely overexposed - through the eye piece, I could just make out one of the bands on Jupiter, and I could make out the overall color better. I've found some info on websites with some helpful tips. So, one of these nights, I'll get out there and try them out, and hopefully get some better video. Once I have that, then I'll start playing around with the video processing software to see how good of a still I can get.
