I just came in from taking some shots - degree of difficulty very high. mount not aligned and with exactly 10 cm above the garage roof and a tree coming into view I did well - 20 Second unguided shot vixen R200SS and the cooled canon running at 1 degree and iso 1600. I have processed nothing yet, this is a crappy shot but at least I can say I took it
too late in the morning to play with this crappy images. stack of 4 20 second shots at iso 1600. the green is a tree, the blue from lights and the clouds are lit up from street lighting. no tracking, badly focused and I should have been more prepared instead of watching a movie and then venturing out to find it clear and midnight,,,,,,,,,,,,,,,:shrug : its really low
I don't think it's crabby at all Houghy, you've done very well both in capture and process.
We know how hard it is to capture from our latitude and it's only that much harder when you don't have a good horizon and light pollution.
Cool, guys! Keep those images coming! I might be in the northern hemisphere at the moment but it's the wrong time of year for clear skies in Vancouver!
Here are some different and remarkeable photo's of 17P, taken in 1892 by Edward Barnard (warning photos a large file sizes).

Great shots Rocket Boy and Houghy
I note the comet has a similar appearance in those 1892 plates, a big dustball with little gas emission, thoush some is noted in the negative image. A very unusual comet with a history of huge outbursts. The nucleous must be very unstable. Because the comet is a short period one and relatively acessable, NASA should give it priority for a space probe mission.

Saw it again last night - couldn't believe how big it was! About half the size of the Pleiades. I could just see it naked eye with averted vision but in the binos it was wow. This is certainly something special.
I concurr Blue Skies, i got up at 2am, i had a slight hangover cos i decided to have a few with the neighbours as it was raining earlier....got up at 2 am and looked out my window and saw stars, walked outside and saw Holmes sitting just above neighbours house.....i was too "out-of-it" to set the telescope up!
So i got some tripod shots as well as visually through the binocluars, i also sized it up against the pleiades!
i saw it again last night, and managed to fire off an image, if i can get out with the scope again soon and work out how to get it properly polar aligned, then i'll try some longer exposures and maybe even some HDR on this bad boy.
