Urban Observer series - GOTO telescope systems by iOptron®
Living in the city or populated suburb doesn’t exclude you from enjoying the night sky. In such environments you need a instrument that can be effective under “light polluted” conditions, portable for the times you head to darker skies, and compact for storage in the limited living space generally available in urban dwellings. Understanding these needs, 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 a urban environment.
The Scope
The Urban 90 featuring an iOptron MC90 Mak-Cassigran telescope (90mm diameter, f 13.3). Mak-Casssigrain 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. Maksutovs 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 Mak-Cassigrain doesn’t require frequent columniation 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 CubeProTM GOTO alt- azi mounts as the vehicles of support for Urban 90. The CubePro 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).
