BAADER IR-PASS FILTER 685nm Size:1¼" 2″ CMOS IMX482The Baader IR Pass filter is a narrowband photographic filter designed for imaging in the infrared part of the spectrum between around 685nm. When paired with a camera that is sensitive in this region (such as the ZWO ASI290MM), this allows you to sharply reduce the effects of atmospheric seeing and capture fine detail on the Moon, Mars, Jupiter and the sun. This is particularly useful when using lucky imaging techniques with telescope larger than 5
