Omegon 106 mm Triplet Refractor: Portable Power with 3.5-inch Focuser
The Omegon 106 mm Triplet Combines Hoya FCD-100 glass, similar to fluorite, with the heaviest focuser in its class: a 3.5-inch with M63 thread that carries camera trains up to 10 kg. With a 700mm focal length (f/6.6), this is an instrument for both deep-sky photography and planetary detail.
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.



Carrying handle and mounting rail in one
The handle on top also serves as a mounting rail for a finderscope or accessories: a smart dual-use that speeds up setup. The super-smooth 1:10 micro focuser allows for precise focusing, even with a heavy camera setup.
With a retracted tube length of 560 mm, it remains surprisingly compact at 106 mm for mobile use.
Included
- Triplet objective 106/700 with Hoya FCD-100 ED glass and air gap
- 3.5 inch focuser with M63 thread and 1:10 microfocus (loadable up to 10 kg)
- Carrying handle with integrated mounting rail
- Scope rings with dovetail mount
Featured accessories
The Omegon Pro UHC 2-inch filter (89 euros) brings out emission nebulae. Visually, the Omegon Cronus 7mm eyepiece (79 euros) provides a high-contrast 100x magnification, and the Omegon Powerbank 10k 12V (39.90 euros) powers the setup on the go.
For whom yes, for whom no
Recommended for: Mobile astrophotographers with a heavy camera train who are looking for a compact tube with maximum focuser travel. Not for: Those seeking the most affordable entry-level option in this class; the AP 96/575 offers comparable optics for seven hundred euros less. Uncertain between the models?
