The profile design of this tube was chosen to allow
dovetail plates (or other designs) to mount to the flat portions
of the two key sides of the tube profile. This eliminates the
need for large diameter, heavy mounting rings. |
|
Shown attached on both sides of the tube is a new 20.0" x 7.0" x 0.815"
dovetail plate. There are four locations on either side of
the tube that the dovetail can be attached. The renderings on
this page show the plate attached at the lowest bolt pattern.
The other three sets of holes can be seen above the plate. The
hole pattern occurs every 2.0". This accomodates imaging
trains from ~4.5 lbs to over 15 lbs. |

Or the telescope can fit between the forks of a Fork
Equatorial or Fork Alt/Az mount. It also allows us to utilize
our Dream PDF focuser, which attaches with
a wide footprint (using large diameter bolts) and simultaneously
offers push/pull collimation. It does this without the need for
adaptors below the focuser. |

Inside the large diameter air filter on the back of
the telescope are high volume, low noise and low vibration fans.
These same fans, in a lower total number of fans, are being used
on a 10" f5 telescope. As well
as another 10"
f5 that Dream produced. |

|
The benefits of Dream's unique filtered air design
are numerous. It allows a much greater volume of air than other
designs. This is mainly due to the enormous surface area of this
type of filter. It doesn't restrict and therefore lower the volume
of air the fan can move (static pressure). As the customer of
the 10" f5 is finding out, moving
air does not allow dew formation either. |

The image to the right shows another 16" Dream
Astrograph being tested out in Dream's observatory. Every telescope
is tested by Shane Santi, Dream's owner, prior to shipping. This
allows testing of not only the mirrors and carbon fiber structures
but also the specific focuser and corrector the particular customer
is receiving. |
