Now we just need these lining the interior of a dome. http://www.engadget.com/2011/06/01/mitsubishi-creates-giant-oled-globe-for-tokyos-museum-goers-cl/...
For several years now I have been dreaming of the LED/OLED dome, unhampered by the limitations of projection. Once the "electric" dome becomes reality I truly...
I think it was Terrance Murtag who first speculated on "active surface" domes. But one problem is the heat - LEDs when packed together like that actually...
* LIPS = Live Interactive Planetarium Symposium Hi all, I am delighted to announce that Go-Dome has become a sponsor of LIPS. We are honored that they are...
Hi all, We've just launched a kid-friendly pointer: It is NOT A LASER, but rather an LED (light emitting diode) pointer. The bright red arrow allows students...
Hello All, Just a quick question. We are in the process of adding a projector-spherical mirror system to our planetarium, we have a 9 m (30 ft) dome with a...
... A comment ... as it happens if a projector works (focuses suitably) then it will work in any size dome. Dome size is mostly related to brightness. There...
We use the Optoma 1060 in our portable domes, and it does fine up thru 6m with our Newtonian mirror system. 9m seems very very large for that brightness,...
Hello Manuel, We have a 1080 working extremely well in a 9 meter dome, and since then a 1060 in a smaller dome. We understand that the 1080 has been withdrawn...
Thanks for your reply, Both projectors have the same lumens, the th1060 has a little better contrast 2500:1 vs 2200:1 for the tx1080. However as you pointed...
Thanks for your reply. It is good news, it means you are able to focus the 1060, which is one of the key factors. What size mirror do you have? If you don't...
Hi, Thanks a lot for your reply, Fortunately for us in the US, we can still find the tx1080 online for about $2000. However the th1060 is a newer projector...
The 1060 focusses well on both the Acril mirror and the Go-Vex mirror from Avela (the Go-Vex mirror is the same size as the Acril, but has a new special...
Hello again, You will have no difficulty focussing on the usual 24" mirror whichever source. Remember, you have to focus an image on the main mirror 400mm x...
Hi Manuel, You can use our Digitarium Gamma, Epsilon, or Kappa single fisheye lens systems next to a starball. We have an elevator mount specifically designed...
G'day All, Life is fun when it is full of debate ! We have naturally always stressed the advantages of mirror projection - we were first to offer it ! This is...
For the big domes, sure, the secondary mirror on the Newtonian isn't really necessary, but for travel with portables it really is super to have a smaller...
... Actually, there is a mirror system built by the Astronomical Society of Kansas City in the Gottlieb Planetarium in Science City's Union Station. That's a...
Hi I'm having a new cover made for my dome and am planning to project directly on the inside of the cover rather than on the suspended screen I've used...
Hi everyone Just thought some of you may be interested in free HD fulldome content (mainly trailers / previews) now available on our new Facebook Page: ...
... Here's a very rough approximation but it gives you an idea why low reflectivity is good. Imagine light incident on a portion of the dome, some of that...
Great, that makes perfect sense. Now how does the 'gain' value given by screen manufacturers relate to reflectivity? It can't be 1:1 as I sometimes see gain...
... For projection screens a gain of 1 is the reflectivity from a standard surface, magnesium carbonate from memory. The measurement is made for incident...
* LIPS = Live Interactive Planetarium Symposium Hi all, Just a quick reminder that the LIPS registration fee will increase to $200 on July 2. If you're...
... Thanks for coining the term "electric dome".... Seems like it is now installed, the last post showed it being cnostructed, the photo of the suspected dome...
... Arthur C. Clarke actually predicted a planetarium with an active surface back in the novel version of "2010" or it might have been "2061." Have to look...
* LIPS=Live Interactive Planetarium Symposium Hi all, I am pleased to announce that Audio Visual Imagineering is sponsoring LIPS. We look forward to learning...
