Omegon ProNewton N 254/1250 OTA - 254mm Newton

Omegon ProNewton N 254/1250 OTA 254mm Newtonian: 10-inch with fan and fine focus

The Omegon ProNewton N 254/1250 is the largest ProNewton tube: 254 mm BK7 mirror with 94 percent reflection, a primary mirror fan with battery compartment and a 2-inch Crayford focuser with 1:10 reduction. Ten inches of aperture means globular clusters break down into stars and galaxies show structure.

The thin spider vanes of the secondary mirror holder keep diffraction low: stars remain sharp and contrast high.

Ventilator 1:10: the details that matter

The built-in cooling fan quickly brings the large mirror to ambient temperature, so the image is sharp sooner. The 1:10 dual-speed focuser makes precise focusing routine, including for astrophotography. The 8×50 optical finder, extension tube, and 1.25/2-inch adapter are included.

Count on a sturdy mount in the EQ6 class; this tube rewards stability with higher class images.

Featured accessories

The Omegon laser collimator (€44.90) keeps the mirrors aligned; every Newtonian telescope should have one in its drawer. An Omegon 13% 2-inch moon filter (€34.90) dims the very bright Moon. The Omegon Pro UHC 2-inch filter (€89) brings out nebulae, and the Omegon UWA 9mm eyepiece (€59) provides a 139x magnification with a wide-angle view.

For whom yes, for whom no

Suitable for: advanced observers and photographers with heavy mounts who want 10-inch performance in a trackable setup. Not suitable for: visual observers without a heavy mount; the ProDob 254 has the same aperture class as complete Dobsonians. Compare on the Dobson page. Are you hesitating between the models?
