20" f2.4
Dream Hypergraph optimized for 100% illumination of
IMX461: 101Mp CMOS detector: 3.76µm pixels, 11656 x
8742, 55mm image circle and 3.16 deg² field.

--"Shane, What astonished me is that I can't find
any star halo around Alnitak (bright star near Horsehead Nebula - referring
to our 16"
f3.75 Dream Astrographs).
How did you do that? Another company's instruments have big,
intense star halos around bright stars. Great instruments." - 10/28/20 |

--"Shane,
I majored in physics and have learned some simple optics theories.
The performance of your instruments shocks me and I want to know
their limit. I talked to my friend about your instruments. He's
an optical engineer and professional optical designer who took
part in the design of the 30 meter
TMT project. Your instrument performance also amazes him
and has triggered our desire to know the level of peak performance
your instruments can achieve. I have done deep sky imaging for
several years and clearly know that design performance on paper
and actual performance are not the same thing. What I really
need is the performance, not overly optimistic design data on
paper. That's why I like Dream's instruments. |
--All
the email responses I've received from you show what a great
company Dream is and what a great designer you are in producing
collection-level instruments. I respect you for your work attitude
toward the optical systems. So does my friend. |
--For
this instrument I want to place it in a world-class observatory.
Chile seems good enough. Do you know any other place that can
push the performance (20 inches large enough, f/2.4 fast enough,
Sony
IMX461 small 3.76µm pixel size) to the limit?"

True Performance Doesn't Fear

It Defies The Status Quo. |

"Your company does phenomenal
work. Dream's engineering sets their lightweight mirrors apart
from competitors. Your engineering goes beyond the lightweight
aspect. You focus on actual (installed)
performance!" |

- Dream customer:
part of a NASA 7-member group project
for NEO search & recovery. Dream's telescope found &
recovered more objects than any other telescope in the project,
including at least one 1m telescope.
|
|
--"Within a temperature range of 10°C we see
no measurable change in focus. Also, there was no change in focus
as a function of telescope position." |
--"The comet discover total for last season
(September 15th, 2012 to June 15th, 2013) for my Dream Astrograph
was 6 comets. SIX! It is assuredly a private facility record.
Sure, there is more to the art of discovery than the equipment
used. None-the-less the 16"
Dream Astrograph delivered
the data. So congratulations all around." |
--"We've had the 16" f3.75 Dream Astrograph
running asteroid patrol now for 7 nights using a 4K X 4K X 9µm
with the 4" corrector. Our software finds between a dozen
and two dozen new asteroids per night as well as many, many known
objects. The telescope has also proven itself in the specialized
area of asteroid recovery. A lot of the Near Earth asteroids
(Objects - NEO) are dim and are not tracked very
much after discovery. Computations give us a probability distribution
telling us where to look to recover such asteroids when they
swing by the Earth again. We use to take many exposures with
the 0.81-m f7 Ritchey (with a 15' X 15' FOV) for this, but the
immense field of view (of
the Dream - 2.25 deg²) allows
us to recapture these with a single exposure on the 16"
Dream Astrograph. This frees up a lot of time on the Ritchey
for other projects." |
--"On average it is discovering 35 new
asteroids and about 400 existing asteroids and/or comets, per
night!" |
|
|
|
"I went
to bed at about 10PM and I let it run all night without focusing.
I blinked through the images and focus did not change. Also, I
did all of my other
images by letting
it run through the night without focusing." |

--"The only thing that gave me NO worries or headaches
was the Dream
Astrograph. This light
bucket worked perfectly the very first time. Collimation was,
after shipment to Belgium and transporting it more than 1000
km by car, almost perfect!! Also focus could stay at the same
position for the whole night, very comfortably!! This scope is
giving me more than I ever could expect from a telescope and
I'm very confident that the collimation will be very stable for
a long time, which is a necessity for imaging remotely! Stars
are perfectly round all over the field and in combination with
the corrector and the ML16803 there is almost no vignetting,
WHAT A REVELATION!!!!
--Shane, a special thanks to you for creating this innovative
product for me. I now understand that perfectionism and short
delivery date cannot go together!" |

"Hello Shane,
I can't think of anyone who has delved as deeply into the mechanics
of telescopes as you have." |

"Thanks for the manual. I think it is
the best treatment of focusing and collimation I have seen. Very
practical and real world. Your descriptions include every small
step and never assume the reader knows them. It's not often that
I see a manual this good." |
