Sky Mentor Light Pollution Filter - 2" - TA-301-3 Mirror Diagonals The high-resolution geared stepper motor

The high-resolution geared stepper motor lifts and supports telescope equipment weighs up to 6 kg

Two additional primary factors played into the equation – Eye Relief (and the related large eye lens size) and Ease of Viewing (a combination of long eye relief and control of pupil aberrations)

some wide-field eyepieces with fields of 82 degrees failed to deliver the same viewing experience as others with similar fields

Sky Mentor Light Pollution Filter - 2" - TA-301-3 Mirror Diagonals The high-resolution geared stepper motorSky Mentor Light Pollution Filter 2" The Sky Mentor Light Pollution Filter is a 2" specialty filter that blocks the visual spectrum except for wavelengths between 480 nm and 510 nm. This type of blocking filter is also known as a Nebular or ALP (anti light pollution) or an LPR (Light Pollution Reduction) filter. This particular transmission characteristic allows passage of ionized oxygen and hydrogen lines, but blocks light pollution sky reflectance
