PRODUCT DESCRIPTION

This apochromatic refractor from the PhotoLine range consists of a dual-element objective lens with an air gap. This combines an Ohara (Japan) “extra-low dispersion” FPL53 lens with a lanthanum glass lens. This combination results in colour correction which rivals that of an FPL53 triplet, but with considerably faster cooling. Even at top magnifications, images remain clear of annoying colour aberrations. This means that the high-speed refractor is not only suitable for astrophotography and wide-field observations, but also for observing the Moon and planets!

The temperature-compensated, adjustable doublet lens sits securely in the sturdy aluminium lens tube. This has internal panels and excellent inner blackening for high-contrast images. The dew cap is retractable for transportation.
