From the Manufacturer
Introducing the FirstScope
In 1609, the world-renowned Italian scientist Galileo Galilei discovered celestial wonders hidden in the night sky through his invention of an elementary telescope. His contribution to astronomy would shape the way we viewed the world from then on. Today, inspired by Galileo, Celestron is proud to offer the portable FirstScope telescope. FirstScope pays tribute to Galileo and many of history’s most notable astronomers and scientists, by displaying their names around the optical tube. We honor the contributions of these men and women while encouraging a new generation of deep-sky explorers.
Navigate the Night Sky like Galileo
This simple Newtonian reflector telescope on a rotating tabletop stand makes it easy to view the night sky. To navigate, move the tube in the direction of the object you wish to view, then observe it through the eyepiece. Add the optional FirstScope Accessory Kit and you’ll receive an optical finderscope that makes it even easier to locate objects.
Despite its large, 76 millimeter primary mirror, FirstScope features a lightweight, compact design, perfect to take with you on your next outdoor adventure. It’s also stylish enough to be a decorative fixture on your bookshelf or desk.
Get Started with Amateur Astronomy
The FirstScope Telescope comes complete with two eyepieces, 20 mm and 4 mm, allowing for magnification up to 75x. This quality Dobsonian-style telescope features a 76 millimeter optical tube with enough light gathering ability to view all the best celestial objects like the rings of Saturn and the Orion Nebula. FirstScope is a perfect option for any entry-level astronomer.

I'm not sure how you would collimate this scope, as it doesn't have an adjustable primary mirror or spider vanes. But it didn't need collimation when I got it (unlike the 4-inch), and it doesn't need it now.
The moon is ultra-sharp through this scope, and you can check my user photo of Saturn for what to expect from the planets.
However, if you buying it to do astronomy (rather than to learn about optics), some advice :
1) Do *not* buy the accessory kit. There is no way you can get your head into a position where you could use the spot finder. Unless you are a squirrel.
2) *Do* buy some better eyepieces and a Barlow.
With the included eyepieces, Jupiter is a fuzzy orange circle. With a better eyepiece and a Barlow, I could see the bands, the Great Red Spot and the poles.
The weakness of this telescope is the included the eyepieces. However, in my opinion, you could throw them in the garbage and the FirstScope would still be a bargain. Eyepieces are replaceable, and you can use them on just about any other telescope.
The eyepieces that come with it deliver good images. But, the 20mm Huygens low-power "wide field" eyepiece that comes with it simply won't do. It's a narrow apparent-field-of-view eyepiece (20 degrees) that only delivers a 1.3-degree field of view. This would make finding anything but the brightest objects (basically the moon, Jupiter and Venus) an exercise in frustration. The 4mm symmetrical high-power eyepiece, in contrast, is fine. It delivers good images in an adequate .4-degree field of view.
Anyone buying this 'scope would be well advised to buy a better low-power eyepiece, such as a Kellner, RKE, or Plossl, in the 20mm to 28mm range. Most astronomy sales outfits grossly overcharge for these eyepieces, but you can find bargains at the surplus optical sites (run a search for "surplus optics") -- I just bought a 27mm Kellner for $12.50 plus $5 shipping from one. One of these better eyepieces will yield a 3-to-4-degree field of view, which makes finding an object easy just by pointing the 'scope in the general direction and sweeping until you find it.
From my heavily light-polluted backyard, the views of the brighter nearby clusters (Beehive, Pleiades, etc.) are wonderful in this 'scope -- its field of view is wide enough to allow you to view the entire clusters. I can't wait to take it out of town next year to check out the summer Milky Way.
Finally, don't bother with the accessory package.Read more ›
