Not strictly Disney but you can see these from any Disney park ;)

No telescope this time, just my Canon 100mm-300mm lens. It's pretty amazing the detail you can get on a clear night.

Nice pics.

I didn't realize there was a star called "dead pixel".


I have done a little bit of reading and do want to take some star pictures. From what I have read you might benefit from opening the lens wider and exposing for the same duration. The stars will be more obvious. The alternative would be using a larger aperture and lesser ISO for clearer shots. Keep in mind the DOF when focused at infinity is rather large ;)

I didn't realize there was a star called "dead pixel".I knew that International Star Registry thing would turn around and bite us! ;)

Nice pix!

If B and H is listening :santa:, I'd like one of those tracking tripods for my Nikon D90. Those darn planets just keep moving out of my frame when I try to shoot! ;)

Great job with a quickly moving target! :goodvibes

I've done the same myself, with my Tamron 200-500mm lens - just backyard, handheld stuff for fun. I will admit to knowing nothing about the identification of astral bodies, so I pretty much just point at the big shiny objects and see what I can get. The moon and several of the obvious planets is about as deep as my knowledge gets. Here are a few:

Crescent moon, Venus, and Jupiter (with some of the moons visible):

If the date in the EXIF data is right (and it appears to be), thats Ganymede on the left and Callisto on the right. That might be a blur or it might be Europa right under Ganymede.


Jupiter and 4 moons (and I can't name or identify them!):

Ganymede, Io, Jupiter, Europa, Calisto


You can do the math or your can download Stellarium (http://www.stellarium.org/), set the clock, find Jupiter and zoom in to see the moons and their names.

Be sure to enable satellites and update them from time to time. It can be useful for answering the "what was that" questions.
