    • Very nice Telescope for Beginers
Style: AstroMaster 70AZ
I have been using this telescope for about a year now and it never bores me. You can easily watch the below celestial objects -> Moon in a very high definition -> Mars -> Jupiter with jupiter's moons -> Saturn -> Venus -> Orion Nebula and many many objects. Pros: -> Very helpfull viewfinder -> The First light software is very helpful -> Sturdy design -> The 90degree prism makes erect images -> Very nice focal length Cons: -> Tripod is very very bad. The movement of the telescope up and down while tracking will be of a big challenge The horizontal rotation is fine. But when u move up and down while u r watching through the eyepiece, it will become very difficult to track due to the spillover movement in the tripod's rotators. WHen u tight your telescope, it gets tight in a different position. With this tripod, it almost becomes impossible to tight the telescope exactly after tracking something. You fix it and the telescope will move and gets fixed somewhere where u can see only blank sky. For such a company like celestron, this tripod is a black mark. -> Heavy vibration on the tripods. The nuts and bolts and joints starts sounding unusually after some days of usage. If you plan to buy this, better buy it along with vibration suppression pads or else it will not be fruitful in long term From a telescope perspective, this is a very nice investment for a beginer to intermediate astronomers. You will enjoy the fun of it when you see it in refractors. My suggestion to celestron is to fix these tripods to avoid frustration on these nice telescopes. The goodwill of telescope is lost because of the bad quality tripod. Overall, this is a product I am enjoying every day. Please be very choosy between reflectors and refractors. And please dont see sun using this. Even with a solar filter, i suggest NO. Refractors get in a lot of light focus which sometimes makes the UV rays even come out of solar filters. Nice product except for the Irritating Tripod. :) ... show more

    • A good budget scope.
Style: AstroMaster 70AZ
Pros: -- Alt-Az scopes are easy to use. Just point and look. -- Comes with two eyepieces, and a 90 degree elbow to turn refracted imagery right-side up. -- Tripod isn't exactly smooth, but it is very sturdy: mount is solid metal construction, a locking tray is part of the tripod to help stabilize the setup. As long as everything is used, it works well. -- Great price for the size. Cons: -- Plastic flashing found inside the lens of the scope, looked like a hair was interfering with the view. Breaking it down wasn't hard (cowl pulls off, inner lens ring twists off and it's open), but someone who is more fearful of messing it up will just return it. -- Like every astronomer enthusiast will say, it's all about aperture. Refractor telescopes are limited in what they can see: you're not going to get National Geographic-style visuals with this. But you can see the moon, planets and nebulae at a broad view. If you want to see Saturn's rings, Jupiter's bands or a distant comet tail, you'll need a larger aperture, period. -- Moon will need a filter on nights with a Full Moon or high reflectivity (this doesn't come with the scope). Without one, it's simply too bright to see detail. Plan on getting one, this scope is great at closer views of the moon from your backyard. -- It's very long. You'll need a way to transport it if you're camping or hiking, so getting a case large enough (with padding) is important if you're going to carry it around. ... show more

    • Amazingly easy to use - recommend buy the powerseeker accesssory kit with it
Style: AstroMaster 70AZ
I love this telescope. It's my first scope but I've borrowed ones in the past and knew this one would be good to learn with because it is not overly complicated and is VERY easy to set-up. I had it put together in less than 10 minutes. The longest time was getting the disc battery into the back of the red light finder (battery is included) and thinking I had a problem when it was just that I had not screwed the battery cover all the way down. The scope is also light for easy transportation by anyone. I bought this in combination with the $20 PowerSeeker accessory kit which was a perfect match. The telescope comes with 20mm and 10mm lenses in storage containers similar to clear film canisters. The powerseeker kit comes with 15mm & 9mm lenses, red & blue filters & a moon filter in a hard black case. The filters screw onto the end of the lense that goes into the scope - easily with no issues in diameter. If you reorganize the filters to fit all of them in one spot in the case you can put all the lenses from the scope and kit in the case. It was a great deal considering the moon filter alone costs ~$15 if you buy it by itself and now I have more lenses and easy storage. I had the scope out for the first time last night after I set it up. I easily found Jupiter, sighted it in with the red dot finder (move your head until the two red dots make a single point and put that point on the object you want to look at), and then looked at it with the 20mm, adjusting the focus knob only a little. I switched over to the 9mm and saw to my amazement Jupiter's orangish colored cloud bands as well as all 4 moons quite clearly. The moon wasn't up so no comments on that but for a first night out this was pretty impressive. The only negative is that although the scope swings easily from side to side if you loosen the azimuth angle stop, it does not move as easily as I'd like up and down to track stars and planets as the earth spins. This may just be a break-in issue and was not that big of a deal. I had no issues with the stand (I was actually impressed with how well it was made for a telescope this cheap) but I had it at it's lowest point as I like to sit on the ground on a blanket and spread my stuff around me. ... show more
