First try out with my new Revelation barlow and remote intervalometer. My target was the DumbBell ( again), plus M101 Pinwheel galaxy.
Mixed results - not dark enough with the fullish moon and astronomical twilight. Then, because I hadn't bother to balance the scope carefully, the tracking was erratic. So I ended up with one 90 second exposure of the Dumb (
Steve) Bell.
Anyway, it looks like the glow has gone.
After spending around an hour taking 10 x 180 second exposures of M101, plus darks and bias, I found I had disturbed the very sensitive power connector and had reset the mount! So, it wasn;t tracking. I had one exposure only, but enought to see the Pinwheel was dead centre. If it had been truly dark, it would have been a good pic ( honest).
