Great Starter Refractor Telescope,
Verified Purchase(What's this?)
This review is from: Celestron 21063 AstroMaster 90 AZ Refractor Telescope (Electronics)
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.

Thank you for the review. It really helped me because I was interested in buying this but have my doubts since I was more interested in deep sky objects. Thanks again!

I agree. Your comment is very helpful for people who
do this as a novice. I appreciate your recommendations for
upgrades. Wish more were like you. Informative ............

Great review! I bought a good 2x Barlow lens, but everything was massively blurry. I couldn't get a good focus on Saturn nor on terrestrial objects. I have seen specs that say the max useful magnification is only 177x. A 2x Barlow lense coupled with the 10mm eyepiece takes this to 200x. Is that my problem? Or do I have a dud of a Barlow lens possibly?
