Well, I finally got my EQ platform built and I at last I can observe at high power with my new 12" Orion Optics Dobsonian.
I made the platform myself because I didn't want to pay £400 for a watch house one, this cost me under half that to make and I am pretty pleased with it. I will post an image or other info if anyone is interested, perhaps even in the right forum!
Anyway Jupiter was lovely at 333x in the Orion. It has 1/10 wave optics and I used a Baader maxbright binoviewer with a 2.6x Baader corrector and a pair of 12.5 Baader genuine othroscopics.
The seeing was average but with several good moments in which I was able to glimpse faint and subtle detail on Jupiter. I'm afraid that the sketch makes it all look more colourful, bold and contrasty than it really was, I do struggle to get everything in my Jupiter sketches, getting the colours right and keeping them delicate and subtle at the same time.
There is a very bright pink oval in the SEB, and the belt itself is divided into two halves as the GRS approaches.
Interestingly for all the subtle detail I could see, oval BA was almost invisible, its effect on the STrB was easier in fact.
Also invisible were the series of white ovals in the north tropical region.
Another feature of note was the white rift in the NEB and a white oval in the NTrZ with accompanying dark ovals and barges in the belts to either side.
The NTrZ itself looked decidedly yellow to me.
The barges in the EZ seemed to be getting whisked away by faster current towards the centre of the zone, and there was a large bright oval area on the setting limb.
Hope you enjoy.
