Bushnell Banner Armored Sentry 50mm spotting scope, 18-36X
zoom, with 45-degree viewing angle.
Bought this near the beginning of my astro career, but not
very well suited for astronomy, although it does a perfectly
adequate job on the larger open clusters, and separates
Saturn's rings from the planet at 36X -- barely.
It is, however, very compact and rugged, making it a plausible
choice when portability is paramount and optical performance
is not at a premium. I would keep it for backpacking except
that it too closely overlaps the capabilities of another
oddball small refractor that I own.
By the way, I am keeping the original tabletop tripod and
substituting another, very similar but not quite as sturdy.
I will have to charge an extra $5 if you want the original
tabletop tripod. Otherwise, $80 plus shipping costs.
