SKYWATCHER ESPRIT 150EDX APO TRIPLET - OTA Only is backordered and will ship as soon as it is back in stock.
The Sky-Watcher 150mm Esprit 150EDX Triplet APO Refractor is a telescope for astrophotographers that are looking for a professional instrument. The correction of the air spaced apochromatic triplet lens provides exceptional colour correction effecting the entire visible spectrum. The Ohara FPL-53 ED (extra low dispersion) glass does an excellent job with no chromatic aberration even on bright stars. The internal reflections are reduced with knife edge baffles for a consequential increase of the contrast, all to help the capture of faint structure in deep sky objects.
To be used for astrophotography, it is recommended to use the dedicated x0.92 flattener/reducer, sold separately.
