I'll say the same, but warm here. I lost some sleep last night finding close
doubles with the 4". I was having trouble with 1, 2, and 3 arcsec doubles on
my SAC Doubles list, but found them all quite splittable last night, using
250x (65x/inch) and even 475x (122x/inch!). It's the Orion 100mm Ed and
performs great in steady skies. Seeing wandered between 7 and 8, with always a
sharp disk, rings always in motion, long arcs or complete, maybe to 9, but
never a 10 tho!
My SAC multiple star list says Epsilon Arietis is 1" (1990), I wonder what it
really is today. The only one that gave me any trouble was 3" Gamma Ceti, a
3.5/6 mag mismatched pair with the companion buried in the first diffraction
ring. Alpha Piscium at 2" was the standout. It's a real beauty. I was able to
split it at 125x and I wonder what its separation really is also these days.
