Please note: This is a Sole Source Notification. Specifications include, but are not limited to: - Projection systems purchased through E&S include custom projector mounts manufactured to specifications based on your theater. These allow for fine-tune adjustments to optimize fulldome image quality. - Once installed, the projectors need to be aligned and blended. This is accomplished manually by an E&S technician or using E&S's proprietary Auto Alignment and Auto Blending systems. These systems operate through Digistar and only E&S has the expertise necessary to integrate new projectors with the systems during installation. Auto Alignment and Auto Blending are optional system add-ons and available at additional cost.
