Dream
Astrograph - 16" - sample images |
 |
We are currently evaluating the most efficient method
for initial polar alignment, the use of Tpoint for polar alignment
data and the use of ProTrack, with Dream's Paramount ME.
Click on the small graphic to the left to see the
latest Tpoint data from a 404 point model. |

The image to the right is series (12 lights and 5
darks) of 0.05s in Ha using a STL-11000M-C2 camera. Processing
by 16" Dream Astrograph customer. |

This image was taken after recent modifications to
the 16" Dream Astrograph. The current telescope is as close
to perfect collimation as local seeing will allow. |
