Jupiter, Io and Europa Animation

I captured some images of the conjunction of Io and Europa last night over about an hour and combined them into an animation: https://www.youtube.com/watch?v=Rdh0ZVh1D0w

Used a 150mm f/5 Newtonian with 5x Powermate and a Philips webcam.

I'm attaching a still image.

A good post on what might work, and what doesn't work, when tackling denialists (in their many forms).

Had some goldfinches in the garden last week and captured some video of them eating dandelions.

Moon & Venus, 21 April 2015

I took some shots of the Moon and Venus setting while looking for Lyrid meteors this evening. The first one is with a 50mm lens and the others are with a 135mm.

I saw three Lyrids over about an hour and a half.

Saw 16 Geminid meteors tonight in about half an hour before the clouds came over, and managed to image a few.

Used a 19mm lens, 15 and 10 second exposures at ISO 6400.

Had to have a go at the big sunspot AR2192, which was easily visible in eclipse glasses, but didn't get much time between the clouds to focus very well.

1/60 exposure at ISO 400 through a 60mm f/15 refractor with Baader solar film filter. Scaled down to about 30% size.
