See the Universe in HD

EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.

True Astrograph Quality

Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Learn more about EdgeHD technology.

Improved Performance

Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron's StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.

Mechanical Features

In addition to EdgeHD's optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.

• Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
• Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
• Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

Individually Tested

Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This "final acceptance test" confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

SST4 Pump has been designed with induction charging allowing for simple and quick charging with no risk of cables and ports becoming damaged and failing. A complete charge cycle takes 5-6 hours. Different charging accessories are available within the portfolio.
• Run Time: The runtime is very important for confined space monitors, as traditional devices with a pumped unit draw a lot of power and struggle to last an entire shift. Based on an 8-hour working day, we designed the SST4 Pump device to run for six working days with the low power catalytic sensor and 12 working days with the infrared sensor. This will allow for more uptime doing permits for confined space entry rather than downtime charging devices.
• Ergonomic Design: The ergonomic design of a handheld device is essential as these devices can be used over a long shift. The slim design and considered weight distribution ensure that the device will sit in the hand and not cause fatigue during a shift. The SST4 Pump can also be worn as a diffusion device. The hose has a bottom connection. The industrial-strength alligator clip makes wearing easy.
• Accessories: Confined spaces take many different forms, and because of this, we have designed several probes, ball floats, and tubing solutions. Conventional solutions must often be designed with the user and application in mind. Our solutions range from sampling ceilings to taking samples in liquid tanks. Also, look at our other accessories for charging, better-wearing solutions, or filtering.
