No need to plunk down thousands of dollars for a portable apochromatic refractor. Just choose Orion's 80mm ED at well under $1000 ? and choose the new .085x reducer-flattener designed to couple with it for shorter exposure times and brighter images.

It's the easy way to get better images from your Orion 80mm ED Apo Refractor telescope. The new Reducer-Flattener reduces the effective focal length to create shorter exposure times that result in better, brighter images.

This is designed exclusively for use with the 80mm ED and optimized for photography with DSLR cameras. The reducer-flattener features three-element optical assembly and is fully multicoated.

The Reducer-Corrector threads onto the focuser drawtube's male threads for a secure fit that will not introduce flexure. T-threads on the camera side accept your camera's T-ring. You will need a "wide" T-ring for your brand of camera, sold separately.

This is a 'must-have' accessory for quality astrophotography with Orion's ED80. Great for daytime terrestrial photography also!
