SKYWATCHER ESPRIT 70EDX APO TRIPLET - OTA Only is backordered and will ship as soon as it is back in stock.
The Sky-Watcher 70mm Esprit 70EDX 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 internal reflections are reduced with some knife edge baffles with 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.
