9mm

I have to say I'm quite happy with my recent purchase of a 9mm Nagler type 6 eyepiece. With my current 8" f/5 1000 mm FL scope and my planned 16" f/4.5 1800 mm FL scope, it gives 111 x and 200 x magnification respectively. The wide FOV makes it quite easy to find things, including M13, M31, M57 the other night, although from my light-polluted observing site there was not a lot of detail (damn you Bellevue!). It was also high mag enough to see Jupiter, currently at opposition, with its four moons and without its southern equatorial belt, missing since May. My medium-term plan is for an eyepiece series: 5 mm UO orthoscopic, 9 mm Nagler, 17 mm Plossl (maybe), and, eventually, a 31 mm Nagler.
