This is one of the 5-inch f/5 telescopes that I'm offering for sale. The telescope has all-wood construction (it was a kit from Stargazer Steve). It comes complete with an Orion red-dot finder on a dovetail base ($40 value) and a 32-mm Antares Plössl eyepiece ($50 value).
Original cost was US$279. Priced to move fast at $100. Cash and carry only -- no shipping offered.

tried to see Comet #PanSTARRS from a hilltop at La Ensenada Lodge on the Pacific side of Costa Rica. but for two consecutive nights we were stymied by local farmers burning crop stubble precisely AT DUSK -- just as we were readying our binoculars and cameras.bummer!

We're in Costa Rica, and there's an ongoing festival called Día Nacional de los Boyero (National Day of the Oxcart Driver). lots of local color amid the festivities, and this street parade -- called a Masquerada -- was a typical example. Note the brass band in the background.

The Moon, up close and personal. I'm looking at a tiny, 0.4-gram sample of lunar dust collected by Apollo 17 astronauts in 1972. None of the particles are larger than 54µm (0.002 inch) across. This is just the sort of stuff being studied at the Colorado Center for Lunar Dust and Atmospheric Science (http://lasp.colorado.edu/ccldas), where I'm participating in the #LASPnewmedia workshop. Thanks to Bob King (http://astrobob.areavoices.com) of the Duluth News Tribune for letting me post his image.

Run of bad luck continues: my most recent try (#4) to fly aboard SOFIA was scuttled by bad weather. This plastic model might end up being what I write about!
