About this image

Have meant to try this for years but the fates conspired. But it was clear tonight and, more importantly, I remembered. As I don't have a CMOS camera, I took a single exposure of 60 starting at 00:09:38 with the idea of encompassing the whole event plus adding some chance for asteroid moons to make themselves known. I hoped for a broken star trail and thats what I got.

The attached is a quick and dirty profile by Astroart. I will try to do something a bit better after dark subtraction and flat fielding. Either way a pleasing result - whatever the numbers end up being.

Now back to the variable nebulae and asteroid light curves....

No problem. Please do. Today has been insane at work and I have only now got some spare time - and it should be clear in 30 minutes - so I've not been near the data today...

Will generate a new dark tonight. Just to be sure.
