Omegon Pro Reducer 0.74x for 140\/910 Triplet APO: your APO faster and wider<\/strong><\/h2>\n\n\n\n

This reducer is part of a telescope: the Omegon Pro APO 140\/910 Triplet OTA. It shortens the focal length by 0.74x and simultaneously corrects the field of view, adjusted to the lens design of this exact 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 does not take into account the field curvature of your lens. This reducer is calculated for the Pro APO 140\/910 Triplet OTA and therefore corrects exactly what that lens's curvature and residual aberrations contribute to.<\/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 0.74x yields<\/h4>\n\n\n\n

After reduction, the telescope operates at 673 mm at f\/4.8. The field of view becomes wider and the exposure time per shot shorter, so you can 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

Built for the largest APO in the line<\/h4>\n\n\n\n

The 140 mm triplet requires a reducer with a corresponding large optic and a wide M88 connection. At 900 grams, this is a hefty component; check that your focus ring supports the total weight of the reducer and camera.<\/p>\n<\/div>\n<\/div>\n\n\n\n
