Style Name: 70AZ Refractor
I have been a backyard stargazer for several years. My very nice 8" Dobsonian Reflector became too much to haul to darker skies away from light pollution, so I have been indoors on starry nights for a couple of years now. When a local camera shop was going out of business, they had a fabulous blow-out price on a Celestron AZ70 Refractor. I know two things about refractors 1) beware of flimsey tripods and 2) beware of extravagant claims of HIGH POWER. I first noticed intelligent power claims on the box (60X per aperture inch TOPS). The Celestron AZ70 suits all my needs. It's compact and light enough to transport easily, it has GREAT optics and a VERY macho tripod and Starfinder with a bright reticle which nailed Venus in 1 easy try right out of the box. Absolutely the best 50 bucks I ever spent and I would GLADLY recommend it to anyone for 4 times that price.

Most folks like reflectors but all of that collimating just turns me off. My AstroMaster is always ready to go in a minute's notice and where I live (southern Louisiana) that's important. Our weather is cloudy for a large portion of the year so when the sky does clear I don't have time to play around with aligning mirrors.

This scope is plenty powerful enough to check out the moon in great detail, Jupiter (you can see the cloud bands) and Saturn (rings are visible). It is also fine for the larger and brighter Messier objects like M31 (Andromeda Galaxy) and M42 (Orion Nebula). I do suggest eventually getting the Celestron lens addon kit for it though as that opens up so many more options and the lenses are just a better quality.

Lastly I will comment on the tripod. I am giving this scope a 5 star rating DESPITE the tripod. It's not that it's flimsy, it's fairly sturdy, but the clutch system makes it really hard to get it set onto a moving object and then to re-position when it moves. Honestly, I usually just mount this scope on top of one of my sturdy video tripods and it works even better. There are threads on the bottom of the scope's dovetail mount that allow you to mount it to a standard tripod and that wins lots of brownie points with me.

Style Name: 90AZ Refractor Verified Purchase
The Celestron Astromaster 90Az Refractor telescope is a great little starter scope. Well I shouldn't really say "little" as it is about 3ft long or so. The Altazimuth tripod is perfect for beginners as you just use it like a normal camera tripod. I prefer this much more than an equatorial mount for quick viewing. If you are new to amateur astronomy you should do some research try to learn what to expect when buying a telescope so you can know what to expect view with it. This is a great telescope for viewing the moon and other planetary viewing, it also serves well for terrestrial viewing. But if you are expecting to view brilliant images like the ones Hubble takes then you probably will be disappointed.

I also have a 4.5 reflector telescope but I can honestly say I prefer this Celestron over the the 4.5 inch one. This refractor gives a much clearer image of objects like Jupiter and its moons than my 4.5 inch. I live in a very light polluted city and I can still see Jupiter and it's moons very clearly, I can just image what they would look like out in the country skies. The Moon looks spectacular. I suggest buying a 2X Barlow lens with this (or any) telescope.

If you are wanting to observe other things like deep sky objects (Nebulas, Galaxies...) I suggest you save your money and buy yourself large aperture dobsonian. Also try to keep in mind that what matters in a telescope isn't really the "zoom" factor as many telescopes try to advertise, but the amount of light it can gather. But if you want something portable and quick to set up and are interested mostly in viewing planets and the Moon, then for the price I highly recommend this scope.

Style Name: 70AZ Refractor Verified Purchase
This is my and my wife's first venture with a telescope so we sought something that would not require a big investment; would not "jiggle or shake" if bumped when in use; would be easy to handle and transport by hand; and allowed us some recreational fun. This item is sturdy and easy to set up but lacks a couple of minor conveniences that could inexpensively been added by the manufacturer to enhance the user's enjoyment. Without detracting from our feelings that there is inherent value in this item to introduce the beginner (especially kids) to astronomy, the changes would be: (1) although the tripod is nice and firm with a locking mechanism, the removable little tray that one snaps inside the legs to hold some of the extras is not easy to put into place or remove; (2) there is insufficient guidance on how to best utilize the infrared eye piece that is battery powered and it is easy to overlook that this eyepiece battery is in the on positon when folding up and storing it and a dead battery will ensue; (3) there is not a protective cap for the 10mm or 20mm lens inserted into the eyepiece if you do not always want to have to remove and store them when not in use; and (4) a carrying case (cloth or plastic) for storage for a few bucks more would have been a nice addition...we're still searching for something suitable. Again, overall it was worth <$100 price paid but I would have been willing to add an extra $10 or $15 for the improvements mentioned above.
