Antlia Oxygen III (OIII) 7nm Prime Narrowband 36mm Filter (ANT-OIII-7NM-PRIME-36MM)

Antlia Oxygen III (OIII) 7nm Prime Narrowband 36mm Filter (ANT-OIII-7NM-PRIME-36MM)Antlia Prime narrowband filters optimize the FWHM (full width half maximum) to 7nm bandpass. The suppression of optical density is (OD) 4 on unwanted wavelengths. The excellent optical coating characteristics found in the Antlia 3nm Pro series has been incorporated into the 7nm Prime narrowband filters. The result is that these filters deliver superior SNR (signal to noise ratio) and better contrast in your images. Antlia 7nm Prime filters are

Computerized Mount Features

Origin centers it precisely in the field of view

random horizontal banding can be removed with multiple frame stacking so it does not affect the final image

it also has a very unique feature: you can unscrew the 2" eyepiece housing and screw on a special T-ring adapter for solid

Sky-Watcher’s belt driven stepper motor system reduces backlash by removing spur gears between the motor and the worm resulting in smoother tracking and less periodic error than mounts using servo motors
