Great work last night Rod. I jumped on it as soon as it came over the side of the shed and have it in the first image at an average of 12.951 M across the first three images I have downloaded (airmass of 1.5)
I should be able to tighten that up a bit when I process the rest of the run.
Data from my first image....
VX For 12.951 SNR 103
126 12.555 SNR 137
137 13.652 SNR 59
More later....
Firrst three images down:

Looks like Rod has bagged a beauty!!!!

Comet 217P/Linear
Excited comet watchers have been following with interest the prospects of Comet 217/P - Linear.
Comet hunters have been following it since David Cardenosa from Bootes Observatory in Spain (J05) reported some outbursts on the 22nd.
My Obs from this morning from D90, whilst I was tucked up nicely in bed asleep.....ah the joys of remote astronomy.
217P C2009 08 26.75348 03 49 59.73 -03 11 43.7 14.05R D90
217P C2009 08 26.75433 03 49 59.90 -03 11 45.5 13.78R D90
217P C2009 08 26.75519 03 50 00.16 -03 11 46.0 13.21R D90
217P C2009 08 26.75603 03 50 00.30 -03 11 46.0 13.70R D90
The comet looked a treat at about Mag 10.8 based on nearby catalog stars. It certainly makes a pretty picture passing those two deep sky galaxies.
As you can see its still holding together reasonably well, although does still have a slightly "out of shape" coma.
From the very useful online application Photometrica you can see the 3D shape of the coma.
Closer inspection shows a similar profile to what our Spanish friends observed.
I am still to download all the files, so maybe more later.
Musically reflecting on this, 217P is proving the time honored truth....."breaking up is hard to do."
UPDATE: I have downloaded the rest of the photos and done a 20 x 20 Sec stack.
