There was some discussion a few weeks ago about show controllers, by that I mean "clean" ways of presenting a range of fulldome content. In this case related...
I have posted about a month back with some questions and i have more info for those of you who have tried to help me out. I am using a 5D canon camera with a...
Hi, I'm selling a standard 5-meter Starlab dome in very, very good condition, no pinholes and no patches, Starlab logo only, including the Starlab dome duffel...
... A wide angle lens but perhaps not a fisheye .... in any case not enough field of view for most fulldome applications. ... Thats more like it, a circular...
so are you saying the fisheye lens (first photo) isnt wide enough? its 180 degree feild of view is the widest bayonet lens you can get. and if i buy your...
... Yes .... it seems like what photographers call fisheye but it isn't what our industry called fisheye, which in photographic circles seems to be called a...
... One more comment .... the 180 degrees quoted for these types of lenses generally refers to the diagonal. This is very different to a circular fisheye that...
Hi to all, I’ve seen the great work of Paul Bourke (is fantastic) I intend to build a planetarium with the technique of spherical mirrors. There are...
... If you are asking about IP (Intellectural Property) or patents on the spherical mirror technique, then no, there are no such limitations. It has been the...
well, then begin to study for the construction of the dome and projection system. we have a projector ACER X1260 can be used for this purpose? Davide Crespi ...
Sorry to bore you with the iDome .... a "small" dome but orientated 90 degrees to a planetarium. In any case, the software, techniques, and applications shown...
so if I understood correctly, I can not transfer to a full dome (almost complete). seeing these document (planetarian.pdf in yor internet page)I thought were ...
Hello Davide, my name is Ramón Vargas and my partner Erasmo and I mount a planetarium in Xalapa, Veracruz in Mexico, using the mirror dome system by using...
... If you are asking about whole hemispherical coverage, yes that is possible with the spherical mirror but it has a penalty. Basically there is a trade off...
... I can't say for sure. The "trick" is whether it will focus on a small enough image. To test it, place the projector such that the image is about 40cm wide...
As Paul says, there are no patents involved in the warping software needed for mirror projection. However, unless time is not money, it is far more efficient...
Our school system is planning on replacing our StarLab with a digital portable planetarium. We are looking at Digitalis Fisheye systems and the E-Planetarium...
... Ahhh, the "best", now there's a tricky question. While I could rightly be considered biased, I try not to be ... here are some general comments, feel free...
While I agree with most of what Paul said, here are a couple of other considerations and a correction: 1) Our Digitarium systems do sit in the middle of the...
I would disagree with #4 . At 1400x1050 or 1920x1080 eyestrain and fuzzyness has never been a problem. -Tony Butterfield  ________________________________ ...
The only fuzziness seems to be in a certain amount of bias. Our Cosmodome total turn key system can certainly perform without any fuzziness, and the total...

Our thanks to those U.S.inquirers asking for the cost of our Cosmodome system. We'll answer each direct, but here's the quick response. For the fully warranted...

If you look at the Full Dome Group you will see the discourse about the growing demand for full dome movies on subjects other than for Astronomy. Such...
Actually those are the only two resolutions we've seen, so in my experience fuzziness is in fact an issue, no matter the resolution. Two of us who noted...
I don't agree that a fisheye system in the middle of the dome is necessarily more vulnerable to tampering than a spherical mirror on the edge. First surface...
