The Night Started Clear

 I rolled the refractor out; it is always a joy using an apochromatic refractor.  The 85mm eyepiece (10x) gives a very wide and crisp field, but has some dust on the field lens that needs cleaning.  Even when the sky was not yet dark, 175X gave a crisp Moon.  Tracking was beautifully accurate.  I definitely need to put the 12" extension on the mount or extend the legs; I was on the ground at one point trying to look through the finderscope.  Then the clouds rolled in from the East.
