⇩ Secondary accessories for OVNI-B ⇩

This list includes secondary OVNI Night Vision accessories as well as selected accessories chosen for their great performance in association with an OVNI-B. 


OVNI Selection - Starizona Nexus / Apex

These 2 modified versions are specially designed by Starizona for OVNI-M / OVNI-B users.

The Nexus is a 0.75x focal length reducer and coma corrector (for Newtonian telescopes). For example a Dobsonian at F/4 becomes an F/3.

The Apex-ED (Short or Long versions) is a focal reducer 0.65x and field flattener (for Ritchey-Chrétien, Meade ACF, APO refractor). For example a refractor at F/5.5 becomes an astrograph at F/3.6.

Price for the Nexus or the Apex-ED (S or L) 599€.

OVNI Selection - Baader BBHS Diagonal

Contrary to traditional diagonals (dielectric...), the Baader BBHS diagonal has high performance in the visible spectrum (400nm to 700nm) as well as in the infrared (beyond 700nm). This is possible thanks to its silver coating.

OVNI-M and OVNI-B are sensitive to wavelengths between 390nm and 1000nm with a peak intensity in the near infrared. This diagonal will maximize the visible details on the whole spectrum of sensitivity of the OVNI-M.

Price 479€.
