I've added my fourth post on my digiscoping series on my blog here:

All of the four can be found from the main page by scrolling down the right sidebar and following the links under "Digiscoping Series" the latest (post 4) is 'Digiscoping - when is FAR too far?!?...' and deals with effects of increased power and atmosphere on image quality.

All around that are posts and images from a recent Tropical birding trip to Trinidad & Tobago and other assorted birdy stuff!

Good birding,
