| Comments: | Bad timing on Jupiter. Waited till after an early bedtime for the kids only to find Jupiter fairly low. I was happy about the weather and decided to take one last parting shot on ol' Jove before the season's end. I found it hanging above the trees and thought I had time. That was until the dec slips again. It seems that the weight of the CFW and camera kill the dec motors at around 20-30* of alt and below. I managed to get things working by pulling the offening equipment out until I got a partial align. They then cooporated after that. Focusing was hard as I've got a longer 1394 cable now. Got that as good as I could on Jupiter itself and then started an RGB coriander sequence. About 20 sec into the Red (1st channel mind you!) It slipped behind the trees. Oh well, next time! On to a recooling session with the cat cooler and the outer ice giants! |
