ZWO Protective Window (for ASI Cameras)

Zwo protective window glass

Replaced glass on my asi294mc OSC camera that had developed a slight scratch. Removed the four screws and picked up old glass with tape and quickly covered sensor to prevent dust from entering. New glass was totally sealed with protective film that I peeled off and then I quickly removed plastic cover I put over sensor, and dropped in new glass (using rubber glove on hand to reduce chance of debris falling on sensor). Tightened screws to what felt like same torque as removed. Easy and quick replacement. First time using Telescopes Canada. Very pleased with their stock, pricing and service. Will use again.
