Wow, Looks like CBS eye, greenish at all powers,
Central star easy at 300X. Very bright, large, round. AT 650X on a
night I rated 8/10 for seeing, there is a small, dark circular area
around the central star. A very nice planetary with lots of internal
detail at high power. |

Pretty bright, pretty large, Round, brighter
in the middle; 165X and 320X, very grainy, no resolution on a night
I rated 5/10. At a much better site on an evening I rated 8/10 the
17.5" would show 6 stars superimposed on a hazy outer corona. |
