    Blog 53: Diamond brooches
    An unforgettable experience at the eyepiece, almost akin to seeing Saturn, is one's first look at a globular cluster. Hanging in the black of space is a spherical mass of stars whose center is so tightly packed that individual orbs cannot be picked out, while around the ball are stellar streamers and loops, the whole conglomeration glowing like gems.

    Blog 50: Astronomical fun
    I was stoked for my astronomy trip Wednesday. For the first time in many months, my telescope was repaired, the new camera system was fixed, weather predictions were for mostly clear skies and the moon would set early. I reviewed the night's most interesting photographic subjects and wrote this list of possibilities -- "For May 16, 2018: "NGC 4438 (and NGC 4435), 'The Eyes,' in the Virgo Galaxy, part of Markarian’s Chain. Take a deep exposure, with long subs, to pick up the many smaller
