Omegon Pro Reducer 0.82x for 61\/335 Triplet ED APO: Your APO Faster and Wider<\/strong><\/h2>\n\n\n\n

This reducer belongs to a telescope: the Omegon Pro APO 61\/335 Triplet ED OTA. It reduces the focal length by a factor of 0.82x and simultaneously corrects the image field, matched to the lens design of this specific model.<\/p>\n\n\n\n

For the owner of this tube, this is therefore the shortest route to a second, faster configuration: attach a reducer and the same telescope photographs wider fields in a shorter time.<\/p>\n\n\n\n

Calculated with exactly this perspective<\/h4>\n\n\n\n

A universal reducer is always a compromise: it doesn't know the field curvature of your objective lens. This reducer is calculated for the Pro APO 61\/335 Triplet ED OTA and therefore corrects precisely what that optical system's curvature and residual aberrations introduce.<\/p>\n\n\n\n

The result is a reduced and corrected field: stars remain round into the corners, even on larger sensors.<\/p>\n<\/div>\n<\/div>\n\n\n\n

What the factor 0.82x yields<\/h4>\n\n\n\n

After reduction, the telescope works at 274 mm with f\/4.5. The field of view becomes wider and the exposure time per shot shorter, so you collect more signal in the same night.<\/p>\n\n\n\n

The back focus follows the industry standard of 55 mm: common combinations of filter drawer, filter wheel, and camera fit without calculations.<\/p>\n<\/div>\n<\/div>\n\n\n\n
