Well Folks, after much deliberation as to what to buy, (12', 10", 8" or largish refractor), I decided to go for the 12". It arrived yesterday, put it together in a jiffy, collimated the laser collimator and then the Dobs. The power of these scopes is incredible, especially after the little 4.5" I have been using for so long. Anyway had a look at quite a few things last night, all my favourites, M104, Centaurus A, M57 etc etc etc, and last but not least was Jupiter. I was amazed at how clean and crisp the views were, and I caught the shadows of two moons at the same time crossing the planet. One of the moons which was making one of the shadows must have been transitting as well but I failed to pick that up. I didn't do any obs reports, last night was just getting the feel of it as it is pretty damn big compared to what I am used to. I will have to spend some time now and go back over all my obs reports with the new scope and right new ones for each object. Anyway just wanted to share the excitement. Woo Hoo!!!!!!!
