I don't believe I've ever seen an 8/70 print (though I'm a big fan of 5/70), but I'm sure it's a great format.

My point was that there would be little reason for anyone to install IMAX equipment if the same film library were available in 8/70, given that the 8/70 equipment and prints are significantly cheaper. Thus, IMAX is using its film library to gain a competitive advantage over the 8/70 and 10/70 competitors.

The 10/70 format is VERY rare and mostly used for special venue shows. Probably less than 10 worldwide...mostly in Asia.
Many, MANY, 1570 films were at least partly shot with 870 cameras and blown up to 1570.
It's virtually impossible to tell the difference between 870 and 1570 projection on screens as large as 80 feet. That is assuming the projector is properly maintained.
I've seen 1570 presentations and 870 presentations that I would not show to my dead grandma. On the other hand, I have seen 1570 and 870 motion projection that the chart-image appeared to be painted on the screen or shown from a slide projector....NO ghosting and NO jump/weave...great flat illumination.... etc.
One thing that REALLY bugs me about 1570 3D projection is image movement relative to each eye. It is really hard to obtain a "rock steady" image with the rolling-loop projection system. Stability is really bad with the dual-rotor rolling-loop machines...I have yet to see one that will match a 2-machine 3D setup. The BEST 1570 and 870 3D I have seen is with separate left-eye and right-eye projectors.
Other (much overlooked) "great image" factors are lens resolving power, magnification factor, and machine vibration that contributes to a "soft" image. A premium 1570 lens can cost between $40K and $65K depending on the application...870s can run $18K to $60K.

Rochester NY has both an IMAX theatre with a pair of new IMAX SR (small rotor) projectors (Cinemark Tinseltown), and a 8-perf 70mm Pioneer linear loop system at the Strasenberg Planetarium (dome screen):

Bobby said........I don't think that particular installation was the best thing to show off 8/70.

They must have been stretching the life out of the bulbs.......I installed the 3D system there......and originally looked very good.

Don't know but the most likely contacts would either by the IMAX theatre at the Cape or the Nat Air and Space Museum as they were co producers of the"Space Films"

There are 8/70 Iwerks projectors in Scotland at Loch Lomond (350 seats) and in Midlothian at the UGC Extreme Screen (295 seats).

In England, there is an Iwerks projector at the Warner Village in South Wirral and two Mega projectors at the City of Durham Millennium Project (250 seats) and in Penrith at the Upland Kingdom Discovery Center (250 seats).

UGC Extreme Screen in Midlothian closed some time ago, not sure on equipment status

Warner Village South Wirral (Cheshire Oaks) was 3D but they have removed one projector and just (last Friday) replaced the silver screen with a standard matt white surface.
They have ? are installing 35mm so they can run MIB II .
