This great starter kit for observing the curiosities of the deep sky includes seven key accessories to help you get the most out of every stargazing session. Let's take a closer look at all the included goodies:   

Orion Expanse Telescope Eyepieces

This affordable kit includes four popular Orion Expanse eyepieces; in 6mm, 9mm, 15mm, and 20mm focal lengths. Every Expanse telescope eyepiece features a big, wide 66° field-of-view for great, dare we say "expansive", views of deep sky wonders such as distant galaxies, ethereal nebulas, and glittering star clusters. The variety of four focal lengths gives you the ability to view at both moderate and high magnifications, so you can study deep sky objects in detail through your telescope. Start out with the 20mm Expanse eyepiece for a big-picture view, then bump up the magnification little-by-little with the 15mm and 9mm focal length oculars. Finish off with the 6mm Expanse telescope eyepiece to get a high-magnification view with a pleasantly wide 66° apparent field.

1.25" Orion SkyGlow Broadband Eyepiece Filter

The included SkyGlow Broadband Eyepiece Filter is an advanced multilayer "interference" filter that blocks the most common wavelengths of urban light pollution while at the same time passing desirable wavelengths with very little attenuation, yielding dramatically better deep sky views. Simply put, the Orion SkyGlow Filter lets you see better, more pleasing views of deep sky objects by enhancing contrast and blocking distracting light pollution. The 1.25" SkyGlow Filter threads directly onto each of the included Expanse telescope eyepieces so you can enjoy optimized contrast in all your views.

Orion DeepMap 600 Folding Star Chart

Use the included DeepMap 600 Folding Star Chart to plot your deep sky observing adventures. DeepMap will tell you just where to look in the night sky to find interesting objects. It's a great guide to the night sky for beginners and advanced amateur astronomers too. Color-coded symbols identify more than 500 galaxies, nebulas, and star clusters - including all 109 Messier objects - as well as some 100 of the most interesting double and variable stars. No other single star chart includes so many objects! DeepMap folds up just like a road map for easy packing, and it's printed on durable dew-proof material for worry-free outdoor use.

Orion AstroGoggles

To get the most out of your deep sky observations, you need your eyes to be sufficiently dark-adapted and optimized for low-light viewing. The red Orion AstroGoggles included in this kit are designed to help your eyes adjust to the darkness quickly, to both save time and optimize your views. Put them on about 30 minutes before you plan to observe to easily prepare your eyes for deep sky explorations through your telescope. With your eyes dark-adapted, you'll be able to notice more subtle features and details in the deep sky objects you explore. Trust us, they really work!

Discover how fun and affordable deep sky observing can be with the Orion 1.25" Deep Sky Explorer Telescope Accessory Kit. Get yours today!
