iOptron Urban 150 f/12 Maksutov Cassegrain Telescope

The iOptron Urban 150 GOTO Telescope System is a 150 mm (5.91-inch) diameter, f/12, Rumak-type Maksutov-Cassegrain Telescope System. This system is effective under urban light-polluted conditions, is portable for the times when you head out to darker skies, and compact for storage in today's limited living spaces. These were the driving reasons why iOptron created the Urban Observer Series telescope mount packages. These portable, easy set-up GOTO observing systems will serve users well living in or near an urban environment.

The Scope
The Urban 150 featuring an iOptron MAK150, Rumak Maksutov-Cassegrain telescope with a 150 mm (5.91-inch) diameter, at f/12. Maksutov-Cassegrain scopes are known for very high-resolution optics, even comparable to APO refractors at a fraction of the cost. The folded optical design results in a compact instrument optimal for transport and storage. Maksutov telescopes also have a relatively high f- ratio compared to other optical designs, result being a darker background increasing the contrast of a foreground object under less than dark conditions. Less fuss, Mak’s are low maintenance, the closed tube eliminates the need for mirror cleaning and the Maksutov-Cassegrain doesn’t require frequent collimation of the optics.

The Mount
Instrument stability is the key to crisp, clear, detailed, views through any telescope. A solid mount that is compact, portable and easy to set-up is a prerequisite for the Urban Observer series. We chose our industry leading AZ Mount Pro GOTO Alt-Az mounts as the vehicles of support for Urban 150. The AZ Mount Pro mounts have the same reliable GOTO and tracking functions as found in more cumbersome German equatorial counterparts however they are a fraction of the size and weight. On top of the size advantage, our Alt-Az mounts do not require polar alignment and can be set up to track and GOTO without a view of the celestial pole (i.e. a tall building in the way).
