## Description

Be ready for the next big comet with Celestron’s special-edition Cometron FirstScope, a compact, lightweight telescope that’s perfect for beginners looking to experience the magic of a dazzling comet, planet, or nebula. This tabletop Dobsonian-style telescope includes a spherical mirror with a generous 76 mm of aperture. The Cometron FirstScope provides bright, sharp views of comets and other celestial objects, and renders the Moon’s mountains and craters in crisp detail. And thanks to its wide field of view, you’ll be able to observe the brightest part of the comet and its tail or favorite deep-sky objects like the Orion Nebula. The Cometron FirstScope offers several upgrades from the original Celestron FirstScope, including 2 Kellner eyepieces and a 5x24 finderscope. Weighing just 4.3 lbs, the Cometron FirstScope is a tabletop telescope that you can take on all your outdoor adventures. It’s also stylish enough to be a decorative fixture on your bookshelf or desk.

Review: IMPORTANT! You will not see Jupiter as large as in the pictures of the "vanilla" FirstScope. - IMPORTANT! You will not see Jupiter as large as in the pictures of the "vanilla" FirstScope. This Cometron version comes with different eyepieces than the Celestron FirstScope with the names of astronomers on it (the "vanilla" FirstScope). The Cometron verrsion comes with 20mm and 10mm eyepieces, yielding 15x and 30x magnification, respectively. The "vanilla" version comes with 20mm and 4mm eyepieces, yielding 15x and 75x magnification. You can still see Jupiter and its moons with the Cometron version, but they look like stars. Despite the lack of extreme magnification (which frankly will look blurry with such a small scope), this scope is a wonderful device! I've used it every clear night since it arrived (about three weeks ago), and I am never disappointed. The included finder scope is a bit of a pain to zero in properly, as it is manual and not an electronic red dot scope, but it works well after some effort. The moon is wonderful, as is seeing star clusters which are invisible to the naked eye. I have not gone out to a dark sky location yet, but I am sure this scope will only impress me even more.
Review: A good absolute beginner's telescope with compromises - I was originally interested in getting into astronomy as a kid, but never did get a telescope. About two months ago, we were cleaning out the house of a recently deceased family member when we found a telescope. I went home and tried it out. However, since it was a Tasco, I wasn't getting good views at all. I decided to do something to dip my toe into astronomy, if you will, by buying this scope, since it is so inexpensive (notice I didn't say cheap). I got it in a reasonable amount of time (desertcart Prime is like that) and opened up the box. Celestron includes two eyepieces, a 20 MM and 10 MM. I believe them to be of Kellner design. While they're not Plossls, they are better than the cheap Huygens design eyepieces you get with a Tasco. They'll do fine for looking at the Moon and certain planets. Overall construction quality of the scope is solid; the plastics aren't glossy and cheap. The tabletop stand it comes on is probably a medium-density composite board with laminate over it. Again, solid; not cheap. However, that is not to say that this is a 100% fully-featured Newtonian telescope. Newtonians, because of their design, require that the two mirrors in the telescope occasionally be aligned properly, in a process called collimation. On the FirstScope, this is a bit of a challenge. For starters, no collimation cap or eyepiece is included in the box. I ended up purchasing one anyways, because I felt I'd need it for something else later on. When it comes to the actual adjustment part of the collimation process, you'll find it's more difficult on this telescope than more expensive models for the reason that the primary mirror (that's the one at the sealed end of the telescope) is not adjustable. The mirror is concave and set into the plastic cap by adhesive. On more expensive models, you'll usually see thumb screws for adjusting it. The secondary mirror (the one by the focuser that bounces light back into your eye) is adjustable, but it is held into place by one long screw instead of a spider. Again, this makes it harder to adjust. Ultimately, I got things to work, but it's something I wish I had known before. Your options as it relates to supporting this telescope are limited unless you can work out a platform mounted to a tripod. I find myself using the trunk lid of my car. It's not a great solution, but it is what it is. This telescope is probably best used for the Moon and planets. Being in a light-polluted larger city (and, as of the writing of this post, in the middle of a very cold Midwestern winter), I haven't had a chance to go and try out for more distant objects. It's possible to see some of the broader details on the Moon and see Jupiter and his larger moons with the provided eyepieces. I just purchased a Barlow eyepiece from a local store, so I'll update with what I see then. Overall, if you're asking if astronomy is for you, and you don't want to drop righteous bucks on a scope just to answer that question, you might be smart to order one of these. I'm enjoying the hobby and plan on purchasing a much more expensive scope soon to see what else is out in the heavens.

### ⭐⭐⭐⭐⭐ The Most Adorable Newtonian Telescope
*by M***G on June 25, 2019*

The telecope is pretty small. So, it's definitely a tabletop telescope. The alt-az Dobsonian-type mount is very easy to use. The 3-inch aperture diameter is good for a beginner's telescope, and for the low price. It comes with a decent finderscope and two Kellner eyepieces: 20 mm (15x) and 10 mm (30x). You can see the moon's craters even with the lower-power eyepiece. I tried to use a separate 3x Barlow lens, but I couldn't see anything. Perhaps it's a focal-length issue. Overall, I recommend this telescope. It makes for a better child's X'mas present than a similarly priced refractor.
