General Info

Class: CPC GPS Schmidt Cassegrain
Best Uses: Planets, stars, galaxies & excellent for Astrophotography!
Recommended Experience: Experienced - Professional

Overall Rating: 8.8/10Celestron NexStar 130 SLT Telescope
Official Review: If you’re looking for a new scope that’s great all-around, has excellent range, and is perfect for detailed Astrophotography, the Celestron CPC 9.25 Inch is a great pick! Typically sold at around $2,500-$3,000, this scope is best for experienced stargazers.

However, it’s high-tech feature set justifies the price, and the CPC 9.25 inch was made with perfect balance between bells & whistles and functionality in mind, and in my opinion: Celestron hit the mark.

Pros: Great GPS system, amazing for Astrophotography, 40,000 programmed objects & has SkyAlign
Cons: Somewhat heavy, complicated features for beginners & fairly expensive for just a hobby

Zhumell 10-Inch Dobsonian

June 1, 2008

Zhumell 10-Inch Dobsonian Telescope Review

General Info

Class: Dobsonian ReflectorZhumell Dobsonian 10-Inch Telescope
Best Uses: Stars, Galaxies & Nebulae
Recommended Experience: Beginner - Casual/Recreational, Enthusiast

Overall Rating: 8.7/10
Official Review: While it’s heavier than other “light buckets”, the Zhumell 10-Inch Dobsonian has a MUCH larger magnification and clearer focus than others in its price ranges. If you’re not sure about the bulky Dobsonian-factor, keep in mind that these scopes are a bit large and difficult to store. However, they are very easy to breakdown and setup, so if you have a decent place to keep it, you’ll be just fine.

That in mind, the major advantage with the 10-Inch Dobsonian is the 600x magnification! You’ll be able to view objects that are much farther away than with the vast majority of other scopes available, even those that cost double the Dobsonian, which is typically sold for about $500!

Pros: HUGE magnification, easy setup & breakdown, very accurate & comfortable
Cons: Somewhat large, 60lbs, no computer-based features, manual tracking, not ideal for lunar/planetary viewing
