M3 - A Ball of Blue Ice

My first attempt at this object. My focus was not perfect; I'm still learning the Stiletto Mark IV device. I promise next one will be better.

Well, its a good start - just nail that focus! If possible, download a continuous stream of images as high compression JPEGc (for speed) while adjusting the focus until it appears correct on the PC screen - sadly there is no substitute for this!
