Good for gauging your interest level
This was my first telescope, so its name is quite appropriate. As others have pointed out, it isn't really a serious observing tool in and of itself, but I'm very glad I bought it, because it introduced me to astronomy as a hobby.

I had wanted a telescope since I was a kid, but they always seemed like an expensive, out of reach object. Once I got older and started reading up on the different models of telescope you could buy, however, I realized that they *might* be within reach after all. But I had a problem; even cheap ones were multiple hundreds of dollars. I didn't want to spend that much on something I would only use a few times and that would then sit unused as my interests moved on. I knew that the cheap scopes you usually see in department stores weren't worth bothering with. So I needed a cheap scope that could do semi serious observing but that wouldn't cost more than about $50. The FirstScope was perfect for that.

The first night I got it I was able to see the moons of Jupiter, something I'd never seen in person before. It was amazing to see them move around the planet as the hours passed by. This scope is small, and quite easy to walk outside with for ten minutes for a quick glance before going back in. And I kept doing so, night after night, week after week. It became clear to me that this was a hobby I was truly interested in, and not just a passing phase. I liked it enough to buy a set of eyepieces, and with them I was able to see the rings of Saturn, the Orion nebula, the Andromeda Galaxy, and the great cluster in Hercules. They were dim and small, but I kept looking anyway.

And that, to me, is what this scope is really good for. If you buy this telescope and use it only a few times, that's fine. It's cheap enough not to be ruinous, and makes for a functional decoration. But if you find you keep using it night after night, staying up for hours and peeking through gaps in the clouds to catch a glimpse of Saturn's rings, you'll know you're serious. You'll know you're an astronomer. I ended up with an Orion XT8, through which I saw the 2012 transit of Venus, multiple solar and lunar eclipses, and a few comets. None of which I would've seen in such spectacular detail if the FirstScope hadn't shown me the joys of amateur astronomy.

(On the scope itself: There is no way to aim the scope other than looking down the tube and guessing. As others have pointed out, the eyepieces aren't great. The 4mm borders on useless, only good for the moon. With the 20mm, you can see the moons of Jupiter, and just barely see that Saturn has rings. You can see great detail on the moon, but deep sky objects like the Orion nebula are dim, and none show much detail. The kit I got included a 32mm eyepiece, which let me see actual detail in the nebula, and a 9mm, which let me unambiguously see Saturn's rings.)

great for beginners
I bought this so that my niece and I could look at stars and planets. We are both beginners, but it's a great view so far. Review by celestron_fan / (Posted on 3/16/2014)
I bought this for my 7 year old son who has PDDNOS because of the sturdy look. Am I suppose to be able to remove black caps off of both ends? I am just not having any luck. Any help would be appreciated.<p><b>OPT Reply:</b> Remove the black cover from the end closest to the focuser/eyepiece. The other end stays the way it is. Use the eyepiece that has the highest number on it (20mm) to look around, and then change to the other one once you have the object you want to look at centered in the field of view. If you continue to have problems, you can contact OPT by phone (1-800-483-6287), by email (internetsales@optcorp.com), or by Live Chat. Please come back and re-rate this telescope once you are clearer about how to use it. Thanks!

Great for the casual lastronomer
I hesitate to use the term beginners telescope to describe this because a beginner who is serious about astronomy should probably get something more suited to serious astronomy. However, as someone with a 40-year casual interest in astronomy, this is perfect for me.

I often step outside to look at the stars and note the positions of a few familiar constellations or the planets. Occasionally I will take out my binoculars for a clearer view, enabling me to barely make out one or two of Jupiter's moons. But binoculars are hard to hold steady enough for detailed observation, and so I sometimes wished I had a telescope. However, I couldn't justify the cost for my occasional quick viewings, and didn't have the space in our small house to store one.

Then I ran across the Firstscope while Christmas shopping online. It was small and inexpensive. Definitely worth a try.

First off, I'm impressed with the solid simplicity of construction. Simply placing it on a patio or picnic table, a wooden bar stool, or even the trunk of a car, provides rock-steady viewing with no fuss whatsoever. For storage it sits handsomely on a bookshelf, ready for action at any time.

The 20mm eyepiece provides slightly more magnification than my binoculars, and a fairly crisp, sharp image. It is great for viewing stars, and brought out far more detail in the Pleiades than I have ever seen with my own eyes. It also helps locate specific objects before switching to the higher magnification 4mm eyepiece.

The 4mm eyepiece is this telescope's weakest part. At 75x magnification, I can see Jupiter as a distinct ball shape, but it is still pretty small, like looking at a pea from ten feet away. I can clearly make out at least three of Jupiter's moons, with no trouble at all. However, the 4mm eyepiece has a very soft focus, creating halos around bright objects, which obscures some details. If you're hoping to see Saturn's rings, as I was, well, it was a little disappointing. I could make them out, but just barely, like two tiny wires sticking out of a very tiny BB, and partially obscured by the aforementioned halo effect. But I did see 'em with my own eyes for the first time in my life, and that was exciting in a small way.

An optional finder scope is available, but as others have noted, it looks awkward to use. I find that by simply sighting along the edge of the tube, I can use the finder scope mounting screws as a sight. I put the object I want to see between the screws, and more often than not it shows up in the 20mm eyepiece view, or darn close.

Because the Firstscope inverts the image in its mirrors, terrestrial viewing is somewhat awkward. But it does give a correctly oriented view if you stand to one side and point the opening behind you. Again, the 20mm eyepiece gives a nice crisp view, but the 4mm eyepiece has a soft focus. However, the latter is able to resolve such details as the filaments in a neighbor's Christmas lights over 200 feet away!

One other minor complaint about the 4mm eyepiece is that only a small portion of the piece is exposed after inserting it, so it is hard to grasp when removing it. Making matters worse, its beveled edge doesn't let my fingers get a tight grip on it.

In all, I'm quite happy with this telescope. It is probably the only one I'll ever own. Someday I'll probably upgrade to a better quality 4mm eyepiece, and maybe add a 2x barlow. But for now, I'm quite satisfied with this telescope as it came out of the box.

Finally, the service from OPT was excellent. I ordered on-line and received the telescope in just a few days. Good job!

Great kids telescope
When writing this review, I kept in mind the fact that this is a $50 telescope. The four and a half star rating is a comparison against other telescopes I have seen in this price range.

When I saw this telescope I thought it would be perfect for my son who likes to come out and observe with me. When I am busy observing or imaging, I usually hand him some binoculars. Yet binos in this range usually do not have enough light gathering, or the ability to change magnifications. So the Firstscope seemed like a great option for a light weight, easy to use telescope he could use when I was tied up.

I received the telescope about three weeks ago and took it out a few nights later. I ran it through its paces and was surprised by the good image quality (for a $49 telescope. It was very easy to use, the focuser was acceptable and the mount (propped on a solid table was pretty solid. It uses 1.25 eyepieces as well, which is great. It comes with two decent eyepieces, but you can use just about any 1.25 eyepiece in it.

I handed it over to my son and he was observing for a solid hour through it. He seemed to have no problems using the telescope and had a blast. Sure, he would rather look through the big telescope, but he was happy to have a telescope of his own. Now whenever I go out observing, my son follows me outside with his Firstscope.

For $50 you cannot beat it.

First Scope
This small telescope is a pleasure to use after making a few eyepiece subsitutions and adding a sighter. A 32mm, 25mm and 10mm plossl eyepieces from my kit makes viewing more plesureable. The 4mm that came with this scope was needed to get a clear view of Saturn and two of its moons. Views of the moon are good. Stars are focused and sharp right out of the box. Finding objects by sighting down the outside of the scope tube is tedious and would be frustrating for a real beginner but it can be done I recommend adding the optional sighter scope as a minimum to simplify the aiming of the scope. I mounted an inexpensive (under $10red LED reflex sighter normally used for a BB gun. After that, finding M13 in Hercules and a other objects by star hopping was easy. I have 3 telescopes of various sizes so I purchased this scope out of curiosity but the Celestron First Scope is quickly becoming one of my favorites for quick viewing sessions or summer motorcycle camping trips where I can't carry a telescope and tripod that doesn't fit in my saddle bag or back pack. It is well made and fun to use . . . anywhere.

First scope
The 4mm eyepiece is useless. Difficult to remove from the unit. If you can supplement with good quality eyepieces, it might make the viewing a bit more worthwhile. Difficult to focus and unit is shaky. Good for keepsake as a cute little collectible in a your book shelf.
For a beginner it is not recommended as it will not create any interest due to unimpressive images.

First scope first impressions
This telescope is a great bargin. It is very well constructed for an inexpensive telescope. It was already assembled and ready to use right out of the box except for one loose screw. I was able to see the rings of Saturn and the Orion nebula without any trouble. Its aperture is too small for any serious observing, but for the price I don't know of any other telescope which even come close.

The telescope has considerable coma at the edge of the field of view due to its extremely large field of view. The image is acceptable near the center of the field of view out to near the edge. The telescope accepts 1.25 inch eyepieces which is a big plus, but better eyepieces don't help the coma.

The only thing that kept me from giving a 5 star rating is that the two included eyepieces are not parfocal and the 4 mm eyepiece is difficult to remove from the telescope if fully inserted into the focuser. I got around the later problem by not putting the eyepiece in all the way before tigtening the set screw, but this just increases the parfocal problem.
