A must-have accessory that’s sometimes provided with some scopes, it attaches to an eyepiece and reduces the light from the Moon, thereby making for a more comfortable viewing experience. Celestron Omni 2x Barlow Lens – a 2x Barlow will double the magnification of any eyepiece you attach to it. Robert Reeves' signature FirstScope comes with a custom wrap that highlights 10 lunar features to explore, including Tycho, Plato, and Copernicus. Learn more about extra solar planets imagery, 3D Star rendering, observation planning, telescope control, multiple-panel printing, and much more. The telescope has a simple portable design that can easily be transported from a bedroom window to a dedicated dark sky location.

ED stands for "extra-low dispersion," which refers to the composition and optical properties of the glass used for the lenses.She holds a degree in physical sciences, a Master’s in astrophysics and a PhD in computational astrophysics. Inexperienced astronomers or children might not notice, but there are better quality eyepieces available that won’t cost you an arm and a leg. With several ND filters to choose from, you can find just the right level of light transmission for the Moon depending on its phase, the aperture of your telescope, and the magnification of your eyepiece. Finding areas of interest is easy, simply rotate the azimuth axis to navigate the Milky Way, open star clusters and deep-sky objects such as the Orion Nebula. ND (neutral density) means only the light level changes

This is about the same as the magnification produced by astronomical binoculars, which makes it possible to star-hop from a bright star or planet to your desired target.

There’s also a few brief notes on observing the Moon, planets, deep sky objects, terrestrial objects and optional accessories. This award-winning optical system reduces visual defects like field curvature and coma, creating an ultra-flat field for pinpoint stars all the way to the edge of today’s largest imaging sensors. Since then, he has become one of the world's best lunar imagers and a prolific author on astrophotography.

The FirstScope 76 promotes fuss-free observing but provides views that will disappoint astronomers looking for an additional piece of kit to supplement their hobby.
