Dubious Value At Best
I purchased this item two weeks ago.My thought was that it seemed like a reasonably priced, perfect addition to the "tools" necessary for a budding amateur backyard astronomy hobby (its advertised contents, construction, and "glow-in-the-dark" planisphere).After closely examining the item for the past ten days, I'm forced to conclude that I was in error, and that you really do get what you pay for.As Celestron is one of the most reputable names in astronomy, I must confess that I assumed that quality would follow in all products that bear their name.I have found that this does not hold true in the case of these sky maps.The major problem with the package is that it is rife with misspellings, letter transpositions, apparent omitted words, and just plain (what we used to call in the old days) "typographical errors."Additionally, when I compare some of the technical information on the maps (i.e., star magnitudes, astronomical distances, etc.)and accompanying descriptions with other authoritative astronomy sources I have in my possession, I also find numerous apparent errors and discrepances.When using a product like this, it is essential that one be able to trust the data and information it contains.Since I'm not able to do this, I must rate this item with one star.When I purchased the item, it was marked down by twenty percent.I note that in less that two weeks since my purchase, the price has been further reduced by another thirteen percent.In this case, don't be fooled (as I was) by an attractive price.AVOID THIS PRODUCT. (I don't have a substitute to recommend at this time.) ... Read more

celestron ultima 2X barlow
The application for this barlow on my 8i/GPS SCT/XLT was to gain higher magnification options from longer focal length and eye relief eyepieces (ELux and Xcel 25-18-15mm)and stay in modest price ranges for everything. COMMON TESTS with the barlow vs. short focal length eyepieces to 8mm was most favorable: a) using both common and wide angle FOV eyepieces and b)testing with and without eye glasses while c) viewing Polaris double, Jupiter & moons and the Moon. Seeing conditions were poor (Dallas, summer, early evening sky with a lot of Moonlight.) Never the less I am pleased with both the Celestron Ultima 2X barlow and the strategy and therefore I "recommended". Shipping was prompt - much better than prior experiences with amazon.com - improvement so noted.

Inexpensive but great addition for your viewing pleasure
This particular Barlow, along with the Orion Shorty, is highly recommended on several of the astronomy forums on the internet.I got this one instead of the Orion simply because Amazon was offering it at about $52 at the time.
