Jupiter 19th Sept. 2012

Thought the seeing looked passable naked eye but nope, good old seeing gods had invoked that fast jetstream that can't be picked with your eye - The camera tells all though Had some tube currents as well. Note to self: set the scope up at least 3 hrs before bothering to shoot, not 1.5 hrs..

Ah well.

C11/DBK618 @ 30FPS F22 2800 from 6000 stacked.

John, still a good result given the conditions. A bit cruel when the high magnification seeing doesn't live up to the naked eye appearance!

Creditable result for the conditions Asi, it seems the passage of Oval BA past the GRS has had very little effect on either, as expected.

Thanks Ivan. It's a cruel hobby this one but I'm used to being treated this way, lol.

Thanks Trevor. Yes indeed, the 2 spots can pass each other at their seemingly (to us) small distance to each other & go unnoticed to each other as usual.

[Shiraz (Ray)]

still a good image Asi - plenty to see. regards Ray

[asimov (John)]

Hi Ray & thank you.

[Troy]

Good image John, certainly better than my jup's at the moment.
My C9.25 needs 1 hr cool down, so 3hrs for a C11 WOW

Hi Troy & thanks. I have the CF model C11 so yes, at least 3 hrs is best. Depends completely on the circumstances of course. Right now it's housed in a room that gets rather warm during the day & the nights are still chilly so it has to drop at least 12-15 degrees. When summer finally gets here there is very little difference between day & night time temps. so less time is required for cooldown.

That's why I have put off buying/building an observatory. 8-)
