Astromania 2" Blue Filter

Designed with multiple high transmission coatings and strong 3mm thick glass, these filters were designed specifically for the Deep Sky Imager PRO. They will also perform perfectly well with standard filter wheels from other manufacturers. Also they can serve as deluxe visual filters. These are not simple dyed glass like standard color filters, these have multiple micro thin layers of special metals deposited on the glass that reject the unwanted light frequencies for more contrast. The Color Filters come in the standard 1.25" diameter with black anodized filter rings. Their par focal design means you will not need to re-focus when switching between filters. These unsurpassed interference filters offer the ultimate in specific wavelength transmission for true color images with minimum exposure times.
