Jupiter June 20th

[asimov (John)]

I'd like to thank the weather gods & the jetstream for gracing me with a 1.5-2/10 tonight

[Lester]

Looked outside and saw the stars twinklling and said to myself noway.

where have I heard that before?

[Lester]

Any way mate nice image considering the conditions. Hope it gets better as the night goes on. I will check your posts in the morning for the ripper.

least you can see stars....

High cloud here stuffing up our views tonight.

Hi Asi,
With webcams for $100 or so giving us better planet photos than professional observatories had a decade ago, maybe we're just expecting too much

...so.... I've attached a photo of Jupiter from my much treasured 1962 copy of "Handbook for Telescope Making" - taken by an American amateur with state of the art eyepiece projection techniques on a 12" reflector.

Might make you feel better.

Graeme

Well thats the thing you see Lester, very little star twinkle at my place tonight old chap. Thanks.

Thanks Graeme...I actually feel good to be able to drag the details present out. Nothing like honing ones skills on nasty seeing conditions!

[asimov (John)]

Wow. The jetstream decided to really sock it to me by 11:30. Oh well, I'm in 'test mode' & trying a few different things so quality of image means zilch to me at this stage.
This is really testing out the 900nc to see what it's capable of & what it's not. Theres no way I could get these with the 840K in conditions such as these without onion rings or too much grain from upping the gamma to kill 'em I don't think. I'm finding out exactly how far I can up the gain before I get unexceptable grain in the final image, which seems to be around 85%. Theres a definite art to the settings to coincide with the conditions...as with any imaging device of course.

I'm really very happy with the 900nc! Love it.

Man asi you must be having the worst luck down your way lately.. You and Lester really deserve some good seeing.

[Lester]

Well done Asi, defineatly no onions there.

Isnt' it amazing how much more detail can be now recorded than even in the last 20 years. The way these advances happen is driven by the more we get the more we want. These images would have been impossible back when Graeme's book was published.

So still a pleasing result Asi.

Hey Asi

Thanks for feeding my Jupiter habit - much appreciated. Shame about the jet stream but I'm still enjoying your results and exploits!

Cheers

Dennis

Go Asi, Go Asi

The cloud has helped me get over my jetstream blues
