Hi Jeff,



Did you say 16" Mak-Cass? Give me a minute to wipe the drool off the

keyboard, for these planetaries are ideal for such large-aperture long

focal legth instruments!



Anthony.

Hi John,



What you are seeing is the wind doing its damage. As much as I wish for

it to be tracking error since it can easily be corrected on the spot, it

is the damn winds doing their dirty work.



Anthony.

Hi Anthony,



My skies in Ireland aren.t the greatest, though. (~ SQM 20.6)



I.ve been batting about 50% with the easier Abells: I got 2, 4, 12, 21, 50, 79, and 81, but struck out on 14, 20, 39, 46, 68, 75 and 78.



The only one so far that was more than a fuzzy spot:

These made better use of my focal length (all at about 600X):
