Omegon Pro APO DoubleED AP 40/180 Sixtuplet OTA - 40mm Refractor

Omegon Pro APO DoubleED AP 40/180 Sixtuplet OTA 40mm Refractor: the smallest astrograph in the range

The Omegon Pro AP 40/180 Astrophotography in pocket format: six lens elements in total, a triplet objective with two ED elements plus an integrated corrector, in a tube that fits any travel tracker. The fast f/4.5 optics capture large swathes of the sky in short exposures: Milky Way fields, large nebula complexes, and bright comets.

An apochromat converges all colors to a focal point. Stars remain white and point-like, without the purple edges of simple lenses: precisely what a camera sensor would mercilessly reveal.

Made for the travel tracker

The helical focuser allows for fine, backlash-free focusing. The rotation mechanism turns your camera to the desired framing, and the M48 adapter connects directly to common camera adapters. The dew shield, Vixen-style dovetail, and tube rings are included.

Thanks to the integrated corrector, the image field is flat right away: no separate flattener, no fiddling with spacer rings.

Included

• Quadruplet-objective 40/180 with two ED elements
• Integrated corrector (six elements total)
• Helical focuser with rotation mechanism
• M48 camera mount
• Dew shield
• Vixen-style dovetail and ring mounts

Featured accessories

The Omegon Powerbank 10k 12V (€39.90) keeps cameras and trackers powered all night, and the Omegon Pro UHC 2-inch filter (€89) brings out nebulae under a light sky.

For whom yes, for whom no

For astrophotographers traveling with a tracker and wanting maximum sky per gram: this is the lightest route to serious widefield shots. Not for those who also want to observe visually; this tube is built purely for the camera. For that, look at the AP 71/490 with included eyepieces. Unsure between models? The Choice assistant helpt.
