Last night I managed to do some serious testing on the moon which was on the meridian by the time I set up. My lasting impression of the session was BLACK. Black, black shadows that I've not seen the like of with my 10" SCT, excellent definition with a plethora of small rilles and craters. Very sharp definition with no flaring etc. Colour? Just the faintest, thinest line of pale blue at high magnifications (ie 6 0r 4mm) on the very rim of the moon that essentially came and went at the point of best focus. That 10:1 focuser is a godend at high power. No colour whatsoever at other lower magnifications that I could discern. There is one disadvantage with a scope like this - the 6mm Vixen lanthum eyepiece I hardly ever used with the 10" or other scopes, it looks like I'm going to have to get a set of fine high power eyepieces for planetary viewing etc. Any suggestions out there? The Baader or Vixen seem OK but do need some advice.
Regards, Allan
