Observing with the Orion
62mm CTR Telescope
The Starblast 62 is a powerful, little telescope! It will show you
all the Messier Objects (the best deep sky objects) and many
more astronomical wonders.
During the final testing of the Orion StarBlast 62 our devel-
opment team took the telescope to Deep Sky Ranch, a dark
sky site 90 miles from the San Jose, CA airport in Paicines,
California. Below is a log of objects we observed over a couple
of hours spread over two nights of testing in February of 2013.
These objects were observed without filters and the standard
20mm eyepiece (at 26 power).
