I’ve created a Picasa Web Album for some sailing pictures shot today from the end of Katajanokka:

I wonder if the 1 Gb space will be enough. On the other hand flickr.com only seems to offer 100 Mb (?)

Barlow test

The big picture shows a normal photo through an f=1000mm F/9.8 telescope with a Canon 20D. The field of view should be around 1Â° 17â€˜ 20″ according to this FOV calculator. The small frame is taken with an additional 2x Barlow lens between prime focus and the camera sensor. It ends up magnifying the image around 2.7- to 2.9-fold. I guess this could be tuned a little each way by inserting the Barlow differently in the focuser or with a T-ring standoff between the camera and the Barlow.

Something to try on the moon or bright planets once the skies are clear again…

Animal macros from 2003

Had these macros of small animals on my homepage for a while during 2003, but then took them away for some reason. Here they are again:

These are taken with my old digicam, a 4 MPix Minolta S404.

In its simplicity, I think one of the better pictures I’ve managed to take…

If anyone more well versed in biology than me can identify the species I’d be delighted to include that information on this page. All photos shot in the archipelago of EkenÃ¤s (Tammisaari) in Finland.
