Meteorite Crash on Moon - Largest Ever Recorded

Video footage of a record-breaking meteorite strike on the moon, which occurred on Sept. 11, 2013 and was unveiled today (Feb. 24), shows a long flash that was almost as bright as the North Star Polaris. Details can be found at Space.com.

Jupiter, again

With a little more fiddling with the software, here is the same image as earlier but I was able to bring out more of the detail.

Jupiter - imaged with new camera

Got my new planetary imaging camera for the telescope on Friday, and since the skies cleared out a bunch on Saturday, I decided to bear with the muddy ground and test it out on the planet Jupiter. Now mind you, this is a new camera (got to learn how to use it) a muddy backyard and the atmosphere, although clear, was extremely unsteady.

Update on Supernova 2014J

Since it's been cloudy, snowy, rainy, and just downright not conducive to astrophotography these past few days (actually, weeks!) I decided to improve on the processing of the images I took of M82 and 2014J on Feb 7, 2014. Here is the updated photo. The lower ISO (1600 vs. 3200) reduced the overall noise and the longer exposure allowed more of the actual color of the galaxy to come out.

Recent observations have determined that the supernova is now starting to dim and is currently only half as bright as when this image was taken. When the skies clear I'll re-image and see how much SN2014J as dimmed.

Galileo's Optical Illusion

Why does a light-colored object on a dark background appear larger than a dark object on a light background?  It's true, and you might have had this experience yourself. In the photo above, the brighter Venus (lower dot) appears larger than the dimmer Jupiter (upper dot).
Well until recently, no one knew why. Now it seems that a neuroscientist at the State University of New York's College of Optometry may have the answer. Check out the article in LiveScience.

Venus in December

Just got around to checking out my first attempt at planetary photography. Since my DSLR couldn't be easily mounted to my eyepieces/scope, I tried my old Casio Exilim EX-Z700 mounted to a 30mm eyepiece with a Celestron camera mount. Here's the result of that effort, after throwing out about 30 images, I found one that was fairly reasonable.

Comet 12P/Pons Brooks

So I finally got around to capturing the periodic comet 12P/Pons Brooks. Since I was not able to capture this comet from my permanent telesc...
