All-Aluminum Dobsonian on an Aluminum Platform
box and mirror box are made of 1"x3" and 1"x4" rectangular
aluminum box with 1/8" wall. All parts have been welded
together, sanded smooth and powder coated for a seamless
covers fit on the front and back of the mirror box, so the
mirror can be transported in its cell with full confidence.
A large handle makes the cell easy to carry.
side bearings are easily removable for transportation.
cell uses an innovative adjustable double sling to support
the mirror. This eliminates any sideways movement of the
mirror as the Platform slightly tilts the Dobsonian structure
through its tracking run.
Commander is used with the telescope for Go-To finding
and tracking of objects. Here is how it works. Punch in
the object you want from the 10,000 item database. Move
the telescope until the azimuth and altitude readings "zero-out."
Center the object in the eyepiece and the tracking of the
Platform will keep it there as long as you want. You can
find things faster and more quietly than with a loud mechanical
go-to system. And with the Equatorial Platform doing the
tracking, there is no field rotation as with an alt/az setup.
You can take long exposures images, as well as do extended
visual viewing of an object.
Owl Shroud was purchased to help darken the field, but especially
to protect the exposed mirror during star parties. Heavy
duty snaps were installed at the bottom of the shroud so
that it could be securely fastened to the mirror box.
