The all-around Askar triplet for the advanced photographer
The Askar APO 103/700 is an apochromatic triplet for demanding astrophotographers. With a 103 mm aperture and 700 mm focal length (f/6.8), it delivers bright images with high contrast and fine details: nebulae and galaxies with true image scale, and visually sharp planets.
ED triplet with serious focuser
The triplet objective with ED glass controls chromatic aberrations, ensuring stars remain sharp points. The large 3.3-inch focuser supports complete camera trains without flexing and provides clearance for full-frame sensors with matching Askar correctors. The transport case protects the tube on the way to dark skies.

For whom yes, for whom no
For: advanced astrophotographers looking for an all-round triplet for deep-sky with the option of visual use. Not for: those who primarily shoot widefield; the FMA180 Pro does that faster and lighter.
