Although I still have no image of Comet 2013US10 yet, at least I have taken my ASI 120MC out of the box and downloaded the software, even though I have not used it. Set everything up for the Comet the other morning but never took into account the  worlds tallest walnut tree. Made a hasty move to a park nearby and was confronted by a wolf like dog and a female dog walker.
She just kept shinning her torch on me so had to explain what I was doing and then after all this I had forgotten an important piece of equipment. Mel ________________________________________

No never, it would be strictly controlled, red filter, box around the laptop etc. :-) I actually bought an ASI 120MC over 6 months ago, thinking I might try a bit of planetary imaging when the moon's in the way - it's still in the box, haven't even loaded the software to run it yet!

Blimey, steady on Andrew!! It will be a night to remember when I have to complain about the light pollution caused by " imager" Robertson.
