Hi everyone,
Here's an image I did couple of nights ago. Its a cometary globule nicknamed the Dark Tower - it has lights too!
This is a pretty deep exposure as you can see from the millions of stars in the background of the image... which is only about 40 arc-minutes tall.
There's a better resolution image at
