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.

I've found that I enjoy using the Barlow when viewing planets and a few DSO's. It provides an economical way to virtually increase the number of eyepieces in your collection. It does introduce a little light loss with my eyepieces (maybe this is normal with all eyepieces), but it is not troublesome.

I certainly recommend this Barlow for those of you who want to cheaply expand your eyepiece collection.

It's a bit expensive (now it's even more expensive than when I bought it), but the one I got is made in Japan, which is a very rare this times when almost everything is made in China.

It's a barlow, so for twice magnification prepare to loose some light, but with this one I haven't noticed a thing (so the high quality glass and coatings worth every cent). Jupiter at 400x is magnificent. You can easily see all color bands (red spot wasn't on my side this time).

A barlow is a must for a amateur astronomer. If you have a limited budget, buy few eyepieces : 25,15,6 and a high quality barlow to double the power of each.

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.

I bought one, it is good but, when I use, it divide by two the light for your eye. So, if you intend to look to the moon it is good, but if you try deep sky maybe you need 8" to 10" telescope. For my 130 Astromaster barlow is not a big deal. It is optical theory I think, and remember when you buy barlow:double power = half light.

This is an excellent quality product. It has been well designed and engineered. It is very easy to use and provides excellent, crisp, clean views when used in conjunction with my Celestron Nexstar 6 SE and Celestron eyepieces. Well worth paying the little extra for this Barlow over other cheaper inferior products.

I'm using this with my inexpensive Meade 90AD-AZ, and it works well. It effectively doubles the power of my eyepieces without any serious loss of optical quality, as long as I don't try to push my scope past its magnification limits. For the price, it performs very well.

this 2x barlow is one of the better ones I've used with my telescope eyepieces. I had a few with poor coatings but this one has good ones. A must for doubling the strength of your eyepieces for your telescope.

Works well with the Celetron 8-24mm zoom lens on my 80ED APO Refractor

I must agree with other reviewers. I've had my Celestron Ultima 2X Barlow (Japan) for many years and wouldn't think of parting with it. It's just that good!!

As far as I've been able to research, this is the best quality Barlow lens celestron offers. Hasn't given me any problems so far, and I've owned one for a year now.
