EvoStar / ProED APO Doublet Refractor Telescopes

For astronomers looking to elevate their viewing experience, look no further than Sky-Watcher’s EvoStar series of apochromatic doublets.

Sky-Watcher EvoStar refractors are the logical choice for the discriminating amateur astronomer looking for an investment in advanced instrumentation for exceptional viewing. With our superior extra-low dispersion glass, whether you’re viewing the moon for the first time or a seasoned astronomer, you’ll savor one of the finest viewing experiences the Sky-Watcher has to offer.

Observatory-Class Optics

The EvoStar refractor lens assembly utilizes a proprietary combination of matched lenses, designed to deliver optimum visual and photographic performance.  Even when observing bright planetary objects, the EvoStar refractor eliminates color fringing to deliver an image with tack-sharp stars.  Central to Sky-Watcher’s color correction is their Metallic High-Transmission Coatings™ (MHTC™), which eliminates virtually all false color.  All EvoStar refractor optical tubes have been light-baffled to minimize stray light, and the tube interior features a matte black finish to prevent light reflections from reaching the focal plane.

Hand-Crafted Quality

Like the optics, the tube is beautifully crafted featuring rolled steel with our Sky-Watcher signature Black Diamond metal-flake finish.  To contrast, the front and rear cells are constructed with a textured off-white aluminum casting.  Whether you’re viewing from a home observatory or at an outreach event, the EvoStar refractor stands out amongst a crowded field of telescopes.

No Need to Max-Out the Credit Card

Apochromatic doublets have some distinct advantages over triplets.  Using two-element objective lenses rather than three reduces optical tube weight and produces higher levels of contrast.   Because of this, visual astronomers will benefit greatly from using a doublet over a triplet, especially when viewing objects with high levels of detail.  Doublets also cool to an ambient temperature faster than triplets, making acclimation quicker.

For the visual astronomer looking to try their hand at astrophotography, the Sky-Watcher EvoStar refractor series provides the perfect pathway to professional-level imaging without the need for a second mortgage.  Doublets cost less to produce, making them considerably less expensive than triplets.  Additionally, fewer lens elements means less glass, which means less weight.  Less weight means you can handle your equipment with a less beefy – thus less expensive – mount.  With these savings you can invest in a new camera or laptop to enhance your photography.
