... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...

RECREATIONAL TELESCOPES . ... ASTRONOMICAL TELESCOPES . ... The first line of LOMO® amateur telescopes 60 – 80 mm in diameter was produced in 1938.

Our line of recreational telescopes consists of several groups of scopes based on their optical parameters. ...

... The latter will also help scientists construct a three-dimensional map of the nebula and should answer some questions about how it is interacting with the Pleiades cluster. Already Gibson and collaborators Kenneth Nordsieck of UW-Madison and Mark Holdaway of the National Radio Astronomy Observatory have added substantial evidence to the theory that the dust and gas the Pleiades nebula is composed of does not come from the famous cluster of stars that gives the nebula its name. ...
