BAADER CMOS O-III F/2 ULTRA-HIGHSPEED FILTER Clearance2024 Low periodic error (< ±

Low periodic error (< ± 10 arc seconds)

RS–232 port

The thumb knobs are positioned above the mounting surface so they do not interfere with the mount and have stainless steel inserts with 5mm hex slots for maximum security

The maximum input current is 10A (normally this power need is not necessary) so a 17Ah power tank or an equivalent battery is sufficient to last at least a whole night

BAADER CMOS O-III F/2 ULTRA-HIGHSPEED FILTER Clearance2024 Low periodic error (< ±The new Baader CMOS optimized O III 4nm 6. 5nm Highspeed F 2 filter is a precision grade narrowband filter with a high transmission at the Oxygen III line at 500. 7nm. The Highspeed F 2 versions are specifically designed to work very well with modern highly sensitive astronomy cameras and telescopes with extremely fast focal ratios faster than f 2. 3 such as the Celestron RASA astrographs. The ultra narrow 4nm bandpass makes this ideal for imaging
