Disclaimer: apologies 'littlebeck'... I couldn't resist posting this first. I'm in a rare mood for blogging, and I thought this picture couldn't wait any longer for its submission into the blogosphere. For the reader, we were both attendant at the ultimate test of the 20"'s guiding using an STV camera - a 5 minute exposure on an alt-az scope, and this pic didn't actually come from my Canon EOS 350D. I was impatiently waiting to test my own camera and its focal-reducing adapter before imminent cloud arrival (see IC410 post). Here is my stack of the 5 good 5 minute shots of IC405. This is such a wierd looking patch of sky, and in this instance the Canon's lack of red sensitivity has enhanced the colour contrast between the different parts of the nebula. The nebula is otherwise known as the Flaming Star Nebula, and this is just the centre surrounding the 6th magnitude star in the shot (the faintest star you can see, unaided). This star was the guide star and was responsible for the STV units loud beeps as it corrected the telescope's position. (P.S. I'm currently listening to Radiohead: Everything In Its Right Place and reading too much meaning into song lyrics).

I (also) see 405... and it is VERY interesting.
