- Dream customer: 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

More examples: LDN1251 (Lynds' Dark Nebula) & IC 5070 (Pelican Nebula)
--"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?" - 11/1/20

 

 
True Performance Doesn't Fear Change.
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!"

  - Ted Kamprath: over 40 years in professional optics


- 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."   - Dream customer

  "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."
