Description:
Conditions Hazy and Moon, tried viewing in backyard, decided on M57 as high
in the sky. At lower power able to find easily even the two locater stars were
in the field, at 60X was circular ring, 120X showed abit larger image and ring
even more obvious-Early morning viewed Mars W/ETX90, is now near 13 angular size
haze took away the brighter Polar Cap, but could detect Syrtis Major, now shades
becoming more easier to see, had to use 200X plus power with Nagler 4.8mm.
