Revelation Adjustable Field Flattener

Revelation Adjustable Field Flattener

This telescope field flattener is ideal for use with both DSLRs and dedicated astronomical imaging cameras. With many telescope/camera and field flattener combinations, the user has to purchase a dedicated flattener for their particular instrument. This adjustable flattener has a built in precision helical extender, which allows for different spacings and gives the user the ability to "tune" this flattener to their particular telescope and camera combination. As such, this is ideal for those with multiple telescopes and camera options. The lens arrangement utilises Ohara Japanese glass for excellent performance.

Please note this product is threaded for use with M48 adapters, you can use an M48 to M42 adapter to convert to M42

The Revelation Adjustable Field Flattener is optimized for refractors around the f5-f/7 focal ratio, but works well with many other telescopes outside this range. There is an etched measurement guide to spacing which runs along the side of this flattener's barrel, giving the user a good guide to a reasonable distance to work at, from which a finer adjustment can be made.

Focal length greater than 1000 mm = 55 mm spacing
Focal length between 800 & 1000 mm = 58 mm spacing
Focal length betweeen 600-800 mm = 60 mm spacing
Focal length between 480-600 mm = 65 mm spacing
Focal length between 400-480 mm = 70 mm spacing

Specifications:
2" push fit fitting
M48 thread
Ohara optics
