About this product

Product Information

Whether this is your first experience with astronomy or you are a seasoned veteran, the Celestron 21024 FirstScope Telescope is an elegant, functional piece of equipment. An Official Product of the 2009 International Year of Astronomy, it's decorated with the names of famous astronomers printed along its barrel, making it a fitting introduction to science. As one of the more accomplished entry-level small telescopes, it is loaded with capabilities and works well with accessories. The Celestron FirstScope tabletop telescope is stylish enough to be kept within your home or office, yet it's built with a 76-millimeter aperture reflector-type optical tube for an incredible viewing experience. The fit and finish of these telescopes are high quality and attractive. The tube has a 300-millimeter focal length for a fast-focal ratio of f/3.95. It comes with two 1.25-inch eyepieces: a 20-millimeter/15x and a 4-millimeter/75x. Other standard 1.25-inch eyepieces are interchangeable with those that are included, giving a range of magnifications for looking at the stars, the moon, or daylight scenery. It also includes a 5X24 finder scope and bracket to help point the telescope at the desired feature in the night sky. With a three-inch lens size and 11.8-inch focal length, rest assured that you can see every detail of the object you are attempting to view. The 4-millimeter eyepiece delivers 75x magnification, and the spherical optics are sharp enough for displaying details of the lunar craters and valleys, the moons of Jupiter, the Andromeda galaxy, and star clusters such as the Pleiades. Its compact Dobsonian design makes the Celestron FirstScope an ideal traveling companion since it is easy to pack up and take with you on your hunt for a clear sky. It can be easily disassembled from its mount while keeping the barrel optics intact to fit within a suitcase. The optical barrel is practically immune from dings and nicks. It withstands dew and avoids thermal distortion along its length. The simplicity of the optical design and sturdy construction are crafted to offer years of use in field conditions.Featuring an easily adjustable angle and twist-lock styling, the Celestron FirstScope Dobsonian Reflector Telescope makes searching the stars as simple as a twist and tilt. The altitude angle is easily adjustable against a Teflon bearing surface, while the azimuth adjustment rotates the scope smoothly on its base. It's designed to be a tabletop model, but the three widely separated, large rubber feet keep the scope balanced on other near-level surfaces without needing a tripod. You or the astronomy buff in your life will get a lot of use from the Celestron FirstScope and its accessories. The steady stable mount and focuser make it usable right out of the box for your viewing please anywhere you take it. This 76mm telescope is the perfect starting point for children and families who want to become more advanced in the science of astronomy. Its quality of build and appearance also make it a suitable keepsake for aficionados who regularly enjoy taking in the night sky.

Plenty of Potential, But With Caveats
The Celestron FirstScope 76mm tabletop "Baby Dobsonian" is normally listed as a beginners telescope. It is easy to use, but there are some minor issues with the design. First, the location of the focuser. In the earlier design, like this one, it is located perpendicular to the altitude axis. While this seems like it would be easy to use, in fact it isn't; you have to lean over the instrument to look into the eyepiece. On the later models this was corrected by rotating it 45°, which makes it far easier. The other issue with this version are the included eyepieces, a 20mm H and 4mm SR. While the 20mm eyepiece is somewhat usable, the 4mm is not. For a "fast" (that is to say, short) telescope like this, you want lower power eyepieces (also, due to the mirror's shape you are somewhat ...

While the 20mm eyepiece is somewhat usable, the 4mm is not. For a "fast" (that is to say, short) telescope like this, you want lower power eyepieces (also, due to the mirror's shape you are somewhat restricted). While the literature that first announced this telescope said that it was capable of up to 180x magnification, in practice that is far from the case. I would hesitate to take it above 50x, which means using a 6mm eyepiece. However, when used with lower power eyepieces, such as a nice 20mm Plossl or Kellner, the views are good. Even a 6mm Plossl will allow you to see Jupiter's Galilean moons and Saturn's rings, though of course not in great detail. There is also no finder scope included, though there is a mount for one. My advice when purchasing this telescope is to buy better eyepieces, perhaps some inexpensive Plossl's and Kellner's, with no less than 6mm focal length. and no higher than 25mm. The newer models rectify some of the design flaws, but there are still plenty of older ones out there, and with simple changes, it has the potential to be a nice little sky sweeper.

Good, for what it is.
I tried to review this yesterday at ebay's request, and I was prompted to start over again twice, including signing into the site again. Sorry, not doing a detailed review again. I like it for what it is. It's a cheap scope that works. Best part is no flimsy tripod. You'll need to replace the bad eyepieces unless you already have better ones like Plossls. Views are pretty good for a 3" mirror once decent eyepieces are used.
