Enjoy ISF-certified imagery even with the lights on with the EPV EF135H-PST2 Polar Star eFinity 2 66.1 x 117.6" EDGE FREE Ambient Light Rejecting Fixed Frame Projection Screen. The EF135H-PST2 is a 16:9, 135" diagonal, EDGE FREE fixed frame screen, featuring EPV's Polar Star, ISF certified, ambient light rejecting screen material.

The Polar Star eFinity Series features an ultrathin, 0.4 inch, black aluminum bezel to maximize the viewable area for the footprint. The Polar Star surface is designed to work with standard throw projectors to provide superb contrast, color balance, and gain for 2D and 3D presentations. This screen material rejects up to 85% of ambient light for use in environments with minimal light control. The EF135H-PST2 is assembled using a spring and grommet system for attaching the wraparound tensioned screen material, allowing for a taut, flat surface.

All hardware is included, and the lightweight split-frame design makes for easy shipping and delivery to install sites. An LED backlight kit is provided with a remote control for added visual appearance. Additionally, a floating bracket for wall or ceiling installation is included to ensure proper alignment with your projector.

Polar Star is an angular-reflective, ambient light rejecting material which provides superb contrast levels, amazing color balance, and just the right gain for either a regular 2-dimension or full-immersion 3D presentation. This screen material is ideal for high ambient light conditions in home entertainment and commercial applications. The Silver-grey protective surface coating is a reflective compound that is textured to ensure proper depth for use in 3D presentations.

To obtain ISF certification a projection screen must meet a list of essential ISF qualities such as accurate color fidelity, uniform spectral response, and black level performance.

Related Questions and Answers

Q: 1. Can I solar align in the daytime to photograph the eclipse ?

A: Exposures will be so relatively short accurate polar alignment will not be necessary. Simply point the mount to magnetic north and that will be more than sufficient; especially since the camera lens focal length will be under 500mm, I assume.

Q: 2. Does the current model being sold have the new illuminator ii? The main product photo does not show it!

A: Our current stock has the Illuminator 2.

Q: 3. Does this come with the alt/azi base or not? The manual leads one to believe BOTH the Tracker and alt/azi base are sold together for $299

Q: 5. Does this tracker have a setting that will just rotate horizontally without tilting?

A: There is no setting , but it is a matter of set-up. Mount the SkyTracker with the camera mounting block level in all directions. The mounted camera will then rotate continuously, and very slowly, across the horizon.

Q: 6. If I have a standard camera tripod and DSLR, can I go straight into photographing the Moon, Orion Nebula, etc., without purchasing *anything* else, or must I also get the counterweight, any kind of wedge, ball head, etc. for it to be a complete setup? I am comparing this to iOptron and need to know what else is required.

A: Using a DSLR should not require you to use a counterweight unless the camera and lens combo approaches the 11 pound threshold. I purchased all of the accessories just in case they were needed I'd have them to use. I only use the counterweight when affixing my ETX to the ball head. Depending on the total weight of the camera and lens, coupled with the stability of the tripod you have, you may want to have some form of counterweight, even if just for the tripod itself, to ensure steady images.

Q: 8. Can this unit be used with film cameras?

Q: 9. Is it’s dovetail foot suitable for Meade 6000 series 115mm refractor?
