Jupiter With C8 1st June

[asimov (John)]

Well, there were no clouds but that's all that can be said. Another fun-filled giant joop undulations & fuzzing in & out evening. 3/10 at best.

These 2 with C8/2Xbarlow/extension tube/toucam.

20FPS 1/25th sec exposure/brightness 55%/Gain 65%/Gamma 5%.

Tried several @ 5/10/15FPS but were total rubbish = deleted.

Theres a moon top left of pics too..see it?...No??....yeah its pretty small, get a magnifying glass out

Hi Mate,

Yes I can see the moon. Wow! I reckon you will resurrect the C8 sales, thats pritty good detail right across the planet considering the conditions.

Keep it going Asi, I'll be able to sell it for and extra $500 now, name your commission.

[asimov (John)]

I'll take the colour DMK as my commission!

BTW I can never remember the name of that camera! Is it DM....abcdefghilklmnopqrstuvwxyORz! ??

[Lester]

Hi Asi,

DFK21AF04 to be precise. That it for me Catch ya.

[sheeny (Al)]

Good one (two?) Azi. It's good to see what a C8 can do in experienced hands (even if the seeing was lousy!)

Asi, I must surrend my title of "master of crook conditions" to ya. Great quality - you sure this sin't with the C9.25?

[asimov (John)]

Thanks Al.

Yes Rob...pretty sure it was with the C8

[ving (David)]

whip that c8 into action asi

hey, i have a question for you guys... you get a c8 and whack say a 2x barlow in it and the f/ ratio doubles right? whe you put an extention tube in there how do you measure the f/ ratio?

[asimov (John)]

Thats a good question Ving. Davo posted a graph from the televue site awhile back showing the differences between F ratio's & extension tubes etc.

Lester & I have noted the difference in the visual size of Jupiter in an F10 SCT with 2X barlow & dropping in an extension tube 75mm long. We reckon it to be 30% larger on the lappy screen with the extension tube added.
