First Jupiter I'm Happy With

[Steve789]

I acquired a SW 127 Mak about a week ago and have been having a go at Jupiter every clear night since. While the results have been significantly better than what I was getting with my 150P the seeing has been pretty poor, until tonight. Managed to get the GRS tonight as well which was a first for me.

LifeCam Studio and 2x Barlow, 80sec avi @ about 17 fps. Best 45% frames stacked in Registax 6 and tweaked in Photoshop.

Tonight was probably the best night for seeing I've experienced, at least since I got the LifeCam Studio.

I'm assuming the 2 dark spots are cloud/storm formations and not shadows cast from Jupiter's moons.

Threads elsewhere identify them as Callisto and its shadow

A VERY nice image! Truly one of the best renderings I've seen. The colour of the GRS is superb!

If anyone wants a freeware-program to identify the Moons at any given time, this is a very nice - and fun - one:

It's French, but easy to switch it to English - and a few others too.

Clear & Still Skies,

Great first effort Steve, thats definately a moon and shadow, clear skies.

Hey thats a great image - and really helpful for me too!. I'm just processing my first effort, and thought the 2 dark spots must be crud on the sensor! If my effort gets close to yours I'll be well pleased.

Well done!

Thanks for the positive feedback guys.

Dave In Vermont that's a useful link I shall download and install that handy piece of software in a minute.

I'm a bit confused about Callisto appearing as a dark spot. Surely if the disk of Jupiter is fully lit by the sun then the face of a moon passing in front of Jupiter will also be fully lit by the sun and should appear as a bright disk not a dark spot? Or is it just a case of the relative brightness of the moon being less than that of Jupiter?

HI Steve - BEAUTIFUL - Just one word needed mate - really nice - I think it may be around the time of a double transit looking at it - the storms are very low contrast and not as distinct as an actual shadow transit - looks like you have caught a tremendous amount of detail with the Mak - they make excellent Planetary scopes.

You should be very proud of that image - very nice.

Jupiter 2 is handy also for forward planning.

Nice picture, not over cooked.
