Two sundogs in my backyard
On september 12th around 18.30 hours local time I saw two really beautiful Sundogs from my backyard. On could be seen between two neighbouring houses, the other right over another neighbour's house. Here are a few shots I shot with my compact camera.

Sundog on the Alm
At the moment I'm staying on the Emberger Alm in Austria to do some deepsky observing and a bit of lunar observing as well. We arrived on Sunday and we had three clear nights on a row. I am getting a little tired with all these short nights. A detailed report will follow later on this year. During daytime there is also plenty to observe, like this Sundog on monday afternoon. Enjoy the images!

Double rainbow
Just after dinner we saw a double rainbow right above the street where we live. I rushed outside to find the pot of gold at the end of the rainbow, but once I was outdoors, I decided that the view was too beautiful to be ignored. I quickly grabbed my camera and shot a few images and after that, I simply enjoyed the view. The new telescope will have to wait a littlle longer (sigh).

Double rainbow
Two weeks ago I got my Baader Herschel wedge. I could not get my 4-inch refractor into focus using my 1.25 eyepieces. I could not turn the focusser inward far enough. Yesterday I visited a fellow observer who is going to shorten my TAL 100RS refractor by two inches. I hope that I can use the Herschel wedge with this "shorter" refractor. I will keep you updated. Just before leaving I shot this image of a beautiful (double) rainbow.

Sundog in the backyard
Yesterday around 16.00hrs I noticed a wonderful sundog, which was very easy to see. On the first image the Sun is just behind the tree to the left. The sundog is the bright spot in the clouds about 10 degrees to the right of the Sun. The second image is a close-up of the sundog.

The images where shot with the camera (Nikon Coolpix 775) set to "auto". I did some level adjusting with image processing software to bring out the sundog a little more. Click on the thumbnail images to enlarge.

Sundogs!

Last Sunday I saw a sundog for the first time ever from my backyard. Sundogs are a pair of brightly colored spots, one on either side of the sun (about 11 degrees from the sun).  Follow this link to find an explanation how sundogs are formed.

I took the image below with the coolpix 4500 (handheld), but in reality you could see the sundog much better.
