Having drift aligned the Titan mount for about an hour or so I tried a 45 second no guidance exposure on M13 with the Canon 450D. The picture below consists of 16 x 45sec exposures at ISO 1600.
Not sure why I got some light pollution in the top left of this picture. I took flats but no dark frames (must do that next time). Not bad for 45s. IC4617 can be seen between 10 and 11 o’clock in the picture about halfway out from M13 just to the right of a distictive parallelogram of stars. Whilst M13 is only 25,000 light years away from us, IC4617 is at a staggering 490 million light years distance.
