Orion SkyQuest XT4.5 Dobsonian Reflector Telescope

Orion SkyQuest XT4.5 Dobsonian Reflector Telescope
Orion's Skyquest XT4.5 is the smallest in their Dobsonian line of telescopes that includes the B00020WZB0 XT6 , XT8 , and XT10. Newcomers to the hobby are always surprised at how large amateur telescopes are, but to experienced observers, this XT4.5 is considered a very small scope. Tiny, in fact (It's so small, astronomers are buying them just because they think they're so cute). Make no mistake, though--the XT4.5 is a full-fledged telescope, and is a serious observing tool that could last you for years.

Your money buys you a lot in this case. Included are a good-quality 4.5" f/8 primary mirror, two eyepieces, a finder, and a CD-ROM with a stripped-down version of The Sky, a software guide to the sky. The scope comes in two cartons. One contains the optical tube, and the other is a flat-packed box containing the base, which you assemble yourself. Orion includes all the hardware and tools you need, and the instructions are well written. Allocate about 30 minutes to assemble and align everything.

See a detailed view of the XT4.5's features

There are a couple of cost-cutting measures. The primary mirror is spherical, not parabolic (this is not likely to affect the views, however). Also, the focuser is plastic. While I've never seen one break, plastic focusers are by nature less robust than metal ones. Finally (and this may be the most serious concern of all), the scope is a little short for an adult. The eyepiece is only 3 feet off the ground, which may force you to stoop over (hint: try sitting on a short chair or stool while observing). On the other hand, the height is ideal for a child, and as a result, I heartily recommend this telescope for children.

Under the stars, the XT4.5 exhibits excellent performance. Once properly collimated (aligned), the optics give clear, sharp, contrasty views. I've spent enjoyable nights using these telescopes, both as a teaching tool and by myself. Jupiter's cloud band and four moons are no problem to see, nor are Saturn's rings. The Orion Nebula is a glowing fan of green gas, with a quartet of tiny stars at its core. Under dark skies (and with some diligence) the XT4.5 can even pull in some of the fainter deep sky objects, like the brighter galaxies in the Virgo Cluster.

Despite the fact that I have a garage full of expensive telescopes, I never feel compromised with any of Orion's XT scopes. As recently as a few years ago, the old adage regarding telescopes was that you must spend at least $300 to avoid buying junk. While this is still mostly true, Orion's little XT4.5 breaks the price barrier in a big way. As long as you can deal with the short eyepiece height, it's a great starter scope.

Pros:

• Very good optical and mechanical performance
• Fully accessorized
• Great value

Cons

• Short eyepiece height
• Plastic focuser

Star Clusters and How to Observe Them (Astronomers' Observing Guides)

Star Clusters and How to Observe Them (Astronomers' Observing Guides)
ASTRONOMERS OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments. Star Clusters and How to Observe Them is a mine of information for all levels of amateur observers, from beginners to experienced observers. It begins with a detailed yet easily assimilated description of star clusters, how they were formed as our Milky Way galaxy evolved, and how they are classified. The latest research has revealed a vast amount of fascinating information about the clusters, along with some spectacular photographs. Modern commercially-made telescopes enable amateur astronomers to see a surprising amount of detail, and to record using CCD cameras, video, webcams or even film some remarkably beautiful and detailed images. There is detailed information on using refractors, reflectors, SCTs (like Meade and Celestron) and computer-controlled telescopes The book includes an Observing List cataloguing star clusters to be observed or imaged using a variety of different instruments, all of them available commercially to amateur astronomers.

Celestron 52248 65mm Ultima Zoom Spotting Scope

Celestron 52248 65mm Ultima Zoom Spotting Scope
The 65mm refractor spotting scope is the most comapct model in the Ultima series. Featuring a 45 degrees viewing angle and excellent mulit-coated optics packed into a portable refractor design, it comes standard with an 18-55x zoom eyepiece. This series was designed to perform well in a range of viewing situations, making it a great all-around optical instrument. You'll love it for observing nature in long distance spotting and it is completely waterproof so you can feel comfortable using it in extreme weather. The green rubber optical tube allows for subtle observation in any nature environment.
