"It's been 6 months now since we had first light on what is Australia's largest privately owned telescope.
The views continue to get better and better. The stand-out one to date has to be glimpsing the globular
cluster in NGC253. Thanks Hubble Optics for the chance to experience the views that I and the ASV have seen
and will see in the future."
Steve Pattie, 2020
"Last night I had 'first light' with the 12.5" f/6 mirror that you recently supplied. It is truly a
magnificent optic! Ronchi, knife-edge, and star tests were straight out of a textbook, and the image of
Saturn was breathtaking. In the future, I will not hesitate to recommend your firm's optics to friends and
acquaintances..."
Tom Dobbins, Contributing Editor, Sky & Telescope magazine, 2007
"Wanted to take the time and say thank-you for the excellent 20" f4.2. Wow is this mirror smooth and
precise! The deep sky views are outstanding! I counted 26 galaxies in NGC 507 group at 200x in
Pisces-Andromeda border. Color is brilliant as blue-greens are in planetary nebulae with this mirror!"
Tom Bakowski, 2017
"Stars are near pinpoints and there is no tendency to astigmatism. Star testing showed even images that were
very nearly the same inside and outside of focus. Using my EZ tester (ronchi eyepiece) showed nice straight
lines and no hint of TDE. This mirror is a winner and I wouldn't be afraid to buy another Hubbleoptics
mirror..."
Dave Chadsey (cloudynights.com), 2006
"A real piece of art (14" lightweight sandwich mirror)..."
Alain, 2007
"The surface of Jupiter was amazing. Contrast of color was deep and details were very sharp, image edge was
knife cutting, even through hazy bad seeing. The surface of the moon had an extra contrast; very very sharp
edged landmark was attractive enough to keep watching hours."
Kazuki Yamane, 2008 — 10" f/4.7 mirror
"We tested it today at my astronomy club. We used the computer program FigureXP, and created a 7 zone mask
for it. We used a very accurate Foucault tester with a video camera. I must tell you that the 14" mirror was
better than I expected... I am VERY happy with this purchase!"
Steve, 2009
"Took a while for the 14" mirror to come in, but well worth the wait!"
Sportsmans-rest, 2014
"Totally dependable seller (20")."
Basimenon, 2011
"I want to express my admiration for your excellent optics. It gave us a lot of pleasant hours under the
southern stars."
Vladimir
"The deep sky objects...wow, I truly have never seen Orion like that, the entire 30mm eyepiece filled to the
brim with nebula, the colors, the tiniest of stars in the trapezium. The spiral structure in galaxies, the
Eskimo, the Owl, all kinds of stuff, just a heck of a lot of fun and most likely the best views of objects I
have ever seen."
Dan Bayer, 2012
"UL20 is working excellent. The mirror quality is excellent..."
Hiroaki Nakamura, 2016
"I can say that the mirror (though not the sandwich mirror) is excellent."
Dave Sommerfeld with his UP12, 2018
"Just dropping you a line to let you know how much I love my 20" telescope. My wife feels like she dropped
to my no. 2 slot ever since she got me the telescope. Thanks again for making the purchase an easy
experience and standing behind your products."
Ian Glasgow, 2023
