Transit of Venus

It has been a busy couple of weeks in Astronomy. Super Moon, followed by an Annular Solar Eclipse, then a partial Lunar Eclipse, and finally the Transit of Venus.  We took a lot of pics of the transit through two different scopes, giving 2 different views. These are our favorites.

TRANSIT of VENUS - 5 June 2012  (Baader filter)

This first image was shot through a Baader filter, with a digital camera hand-held to the eyepiece of our 25x birding field scope.

The Baader filter gives a warm yellow color to the sun's disk.

Venus is the large dot on the right, and a number of sunspots are visible.

TRANSIT of VENUS - 5 June 2012  (Coronado solar scope)

This second image was shot through a Coronado solar telescope. This scope allows us to see prominences around the sun's perimeter - or "limb".

Venus is the large spot on the left side of the disk. If you look closely you can see two large prominences - one at 1:00 and the other at 6:00.

It was pretty amazing to get such nice photos from such a simple technique.

It's also amazing to remember that earth is about the same size as Venus.

If you missed this transit of Venus, you'll get another chance in the year 2117...
