I went up to a little observing spot I have just up the Hume Hwy. Seeing started of poor and by the time I left it was still about 7/10. I had a peek at jupiter through my 12" lightbridge and I must say I am impressed. This was the first time that I had looked at it high in the sky with my new scope and the detail was just amazing. There was heaps of detail between the main bands and even in them, and this was only at 170x. I had never seen such detail with my old 8". A quick star test revealed that my collimation was a bit of (probably due to the fact that I collimated before the mirror had cooled) so I can't imagine how good the view would be if it was spot on. The star test also revealed possible slight astigmatism, most likely a pinched secondary (The primary was removed and then replaced by Anthony at BINTEL so I'm sure the screws aren't to tight). Over all it was a great night even though we decieded to end it early at about 8pm due to the cold (Ice was forming on the car roof).
