Code: 2458360 High Quality Baader Contrast enhancement filter with strong chromatic abberation reduction for achromat refractors
HIGHLY RECOMMENDED
High quality Baader filter for 1.25" threaded eyepieces greatly boosts contrast while eliminating much of the visible effects of colour aberration (blue-violet hue seen along bright lunar limb and around brighter planets) inherent to achromatic refractor telescopes. Features multi-layer coatings for 95% transmission. It is also a terrific contrast booster for observing the Moon or planets with any telescope - emphasising the contrast of surface detail and atmospheric banding and disturbances in the atmospheres of gaseous worlds Jupiter and Saturn.
