Your GSO type Dobsonian, although entry
level, has optics that are on par with telescopes costing thousands of dollars
more.  However, your Dobsonian is not so user
friendly without added tools to help searching objects at night.   This is
why we designed the EZ PUSH TO.    

Our system takes advantage of the advances of
smart phone and encoder technology to produce an observing system that would
have been very costly just a few years ago. 
By utilizing the smart phone’s excellent display, Bluetooth and GPS
functions, our app turns your smart phone into a high powered observing
instrument.  In addition, we use the newest
wireless magnetic encoder technology that are both very accurate andvery low
power consuming.  This creates a system
that is both economical and accurate.

It is our hope that the  EZ PUSH TO kit on your dob will rekindle your
forgotten passion of watching the night sky. 

You are probably thinking that the EZ PUSH TO app
is just another sky map or general app for telescopes.  You are wrong!
  Most sky maps on a laptop or mobile phone apps do not provide for
improving accuracy as you are viewing.  You
can see lots of gorgeous sky map on 3rd party app, but they almost never
provides any algorithm or tool to improve your system's accuracy.  This is
why most  telescopes very often go to a  given target, only to find that the object is
not there. Often the object may be several degrees away.  The EZ PUSH TO interface
includes a highly accurate level meter and utilizes a visual multi-star
alignment.  All of this is to  improve system accuracy and ensure a pleasant
viewing experience.

The wireless Bluetooth electronics installed
on the Dobsonianare designed to be exposed outdoors to enhance wireless data
transferring. All the parts is designed to protect against humidity, and there
is an automatic fuse to protect the power supply. The construction is made of
durable metal and removable for convenient storage. It looks very simple, but
is precisely manufactured.  Each unit is individually
tested for quality and accuracy.

The installation is very straightforward - just
put on the azimuth and altitude encoder modules on the Dobsonian – installation
only takes a few minutes. Connect Bluetooth with the smart phone, which
automatically looks at your GPS location and local time. Next, you would test
your leveling of your base by  putting
your phone on the base of the dob, and turn around to adjust the level.In
seconds, the system is initialized.

is  designed for visual observing. 
It is not intended to be a complete sky encyclopedia.  The app’s database
includes just about all the objects that someone would want to view such as the
Messier/NGC /Herschel catalogue, double and binary stars, comets and small
bodies, and magnitude 9.5 stars (110,000 stars).

EZ PUSH TO features lots of other amazing
features such as roaming in the deep sky and naming unknown sky objects for you.
EZ PUSH TO is designed to bring you in reach of the real deep sky inyour
backyard,  camping or at a star party.



Unlike EQ mount, Dobsonian is supported on the azimuth / altitude mount which is definitely more complicated. Here, we are talking about accuracy rather than encoders resolution.  The azimuth and altitude encoders are non-contact design, and their resolution is 0.08°, but displayed in app as 0.1°.  Because  some issues in installation (such as horizontal and vertical motion on Dobsonian wooden base are not exactly 90°, or putting Dobsonian base on uneven ground), actual system accuracy would be 0.5° or worse.  However, the accuracy could be improved easily if multi-stars is aligned.  Generally, the accuracy on calibrated system ac could be 0.2° or better.  This is really a challenge for a wooden base Dobsonian.

GSO Dobsonian  Introduction

Sturdy and Reliable Construction:   The telescope's f/6 optics and 1200mm focal length delivers great observing performance. The secondary mirror has a 62.5mm minor-axis and its alignment can be adjusted with a Philips head driver in perfect alignment for the best views possible. Our tube designed GSO Dobsonian looks not so fascinated compared with other movable truss constructed Dobsonian.  However, the optical axis of symmetry in tube constructed GSO Dobsonian is most reliable among all products.

Fabulous Focusing Mechanism:   The GSO Dobsonian telescope features a machined, 2" Crayford focuser with dual-speed adjustment control. The fine-focus control knob allows you to dial-in details at a 10:1 ratio ultra-precise focusing. An included adapter allows use of both 2" and 1.25" sized telescope eyepieces, and both holders feature non-marring compression rings to keep eyepieces in-place without scratching.

Motion of the GSO Dobsonian in both altitude (up/down) and azimuth (left/right) is silky smooth thanks to azimuth high cost roller bearings, adjustable ball-bearing altitude trunnions. Tension of both altitude and azimuth motion axes can be adjusted easily, without using tools, to support heavy accessories on your GSO Dobsonian anytime.

Dobsonian Accessories:  Two telescope eyepieces are included: a big 2" 5-elements Superview 30mm focal length, and a 1.25" 4-elements Plossl 9mm focal length eyepiece. A handy eyepiece rack for the GSO Dobsonian base is included, which provides a convenient storage spot for your telescope eyepieces and other accessories. A 35mm-length 2" extension adapter is also included.

The included 8x50 finder scope is bright aiming tool for the 8" Dobsonian telescope. To reduce cool-down time, an included cooling fan can be plugged in (fan battery pack requires 8xAA batteries - not included) to help circulate air in the reflector optical tube for fast performance.
