So I just got back from the first meeting for my new Astronomy class here at the College of San Mateo in the SF Bay Area, and I was enthused to learn that our brand new, nation-wide one of a kind planetarium is decked out with a GOTO CHRONOS opto-mechanical space simulator from GOTO Optical Mfg.Co (hand built from Japan...worth about 750k...the thing is actually pretty wicked looking) and the Digistar 3 SP2 HD projector from Evans & Sutherland, which is essentially TWO 1080p projectors forming a giant dome image. http://collegeofsanmateo.edu/astronomy/newplanetarium.html (pics and more tech info).

Needless to say I was impressed...the image Definitely held up, and rivaled that of an IMAX dome presentation. We watched a video (aptly narrated by John Rhys-Davies) which consisted of mostly CGI renders of the universe, or of ancient Egypt. A lot of the time I had to remind myself that I was only looking at a 4th of the image and had to spin my head around to get an impression of the overall image. I'd imagine if I sat directly in the middle it would have been quite an experience. I just had to share this here because I felt like the only one drooling over the fact that we were basically getting an IMAX experience in a class at a community college.

nice thing, immersive cinema, huh?
We are using our camera for just that thing: attaching a 6mm fisheye lens with custom relay optics to fit the image onto the sensor, which gives you what we call a dome master (i.e. a 30fps 220° FoV polar fisheye stream for playback in a dome).
Then, remind youself that the RED has more resolution to offer than the dome system you saw! Visit the Chabot Observatory or the new Morrison Planetarium once they are open, and see what can be done in terms of resolution!
Pictures are coming soon - promise!

Hi Tom: Any possibility of the pictures that you mentioned coming? I'd be very interested. I tried your website but it is under construction....

Wonder if there is a planetarium dome move with desert day and night shots? That would be so cool to see for me. :biggrin:

Hi guys,

Sorry to dig up an old post, but is you would like to see some RED shots done for planetariums / domes you can check them out on my Vimeo page.

There are a few time lapse / CG vids, but quite a few RED clips that I have shot.
