Taken on Friday the 15th September 09, from Austerfield with the FLT98 and M25C. It was an Open Night, but cloudy so, for the first time, Dave Hardware and I, stayed away, unfortunately some members came round, and I'm sorry that I wasn't there, but the St John Brigade people were and they had all the lights on in all the buildings. But it was cloudy anyway.
It cleared up about 10.30 so I went down and took this of M31, almost at the top of the sky. The exposure was 18x300sec and the processing was done in Astroart4 with some in Photoshop7. You'll note that I didn't get the centre of the galaxy in the centre of the frame, I didn't notice this till it was too late, unfortunately, so I didn't restart as perhaps I should have, but if I had, I'd have lost a lot of time as the clouds returned by 2.30pm. No darks as usual, but I'd noticed a dust shadow in the middle of the frame, so took some half second flats. I can frequently dispense with flats if I use Gradient Xterminator.
