Bizibilder has been thinking about upgrading (i.e. rebuilding) his observatory. The one he has is fine but is a bit small and offers little protection for himself or the computer on a cold winters night!
He has been using Sketchup – which is, he has discovered, very easy to use for this sort of 3D design work and can be learned quite quickly. It leaves you with a fully dimensioned drawing of more or less anything you wish and have the time to produce. The drawing below represents about four hours work – and that is by someone who is essentially starting from scratch.
All that is missing from this “roll off roof” design are the roof panels – as they would hide all the constructional details. The design is 7’ x 9’. There is a panel under the front edge of the roof that is the front of a small so-called “warm room” – unheated but out of the cold and wind!!
And with the roof closed:

The above are all made from the same 10,000 frame movie that Bizibilder took the other night. He has been playing with his processing software to try and tease out the most detail of the planet. The “big” image uses the “drizzle” technique to make a 1.5x image from the original data – it makes a good image but does not reveal any further detail.

I decided to try and improve the images from my planetary camera by running a series of tests at different camera settings. Unfortunately some hazy cloud rolled in and put an end to further experimentation. I'm quite happy though as these are by far the best Jupiter images that I have ever taken with this camera and scope combination.

Taken between the clouds last night. The moon visible is Io along with its shadow transiting the disc of Jupiter itself. I've tried to change my processing - so, hopefully, these appear rather more subtle.
If you could stand on Jupiter (you can’t it’s just a ball of gas!) within the black “dot” shadow of Io you would be seeing a total solar eclipse!
