Refractors are known for their crisp, high contrast views of the Moon and planets and the Astromaster 90 delivers sharp views right out of the box. The low power 20mm eyepiece (50X magnification) nicely frames the moon, while the high power 10mm eyepiece (100X magnification) delivers a crisp close up image full of detail. The sharp Achromatic optics of the Astromaster 90AZ show me memorable views night after night. On a moonless night I like the way the 20mm eyepiece frames the ghostly glow of the Orion Nebula. Zooming in with the 10mm eyepiece, I can easily pick out all four stars of the Orion Nebula’s embedded quadruple star the Trapezium.
The AstroMaster 90 AZ also features a newly designed Alt-Azimuth mount and tripod. The tripod comes fully assembled, and the telescope simply clamps into a standard dovetail. This new tripod seems reasonably solid, I had no trouble focusing on the Moon and stars even with the high power eyepiece. An Alt-azimuth mount, of course, is best used at low to medium powers because it does not track the motion of the stars. As soon as you get the Moon centered in the eyepiece, it starts drifting toward the edge-this is caused by rotation of the Earth. Celestial objects will stay in the low power field of view for three or four minutes, but with a high power eyepiece they may disappear in a minute or less.
Celestron’s AstroMaster 90 AZ is one entry level telescope that offers great views during the daytime as well as at night. The sharp optics produce a right side up image, the mount is easy to use, and the included planetarium software helps you find planets in the night sky. --Jeff Phillips

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.
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.
