Optolong IR Pass685 Planetary Filter 1.25" Mounted (OPT-IR685-125)

Optolong IR Pass685 Planetary Filter 1.25" Mounted (OPT-IR685-125)Optolong IR Pass 685nm filter is designed to block wavelengths below 670nm and can be used in IR LRGB imaging to produce a sharper luminance image for the best planetary contrast as atmospheric seeing and distortion is much reduced at longer IR wavelengths. The sensor of CCD or CMOS cameras is capable of detecting light in the 350 1100nm range including infrared wavelengths. Thus RGB planetary images taken with IR as the luminance channel have visible

The TeleVue Ethos is essentially multiple eyepieces

Aspheric 2" eyepieces are launched against the world's most powerful large-field eyepieces and offer compelling advantages: higher star-limit size

Many of images of planetary nebula and supernova remnants are taken only with H-alpha and OIII filters

The name Dobsonian comes from the telescopes inventor
