Product Description
Barlow lenses offer an easy, economical way to increase the magnification range of your eyepieces, and Celestron carries an assortment of these highly useful lenses. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length. For example, an 18mm eyepiece used with a 2x Barlow lens would have the magnifying power of a 9mm eyepiece. It's like having two eyepieces in one!If you're looking for an affordable way to achieve high-power viewing of the moon and planets, double stars and even close-up views of terrestrial subjects, a Barlow lens is the answer.Barlow lenses mount into either your telescope's focuser or visual back.The .96" Economy model is a good choice when you want to expand your power ranges at a very economical price. Celestron's premium quality 1¼" achromatic Barlow lenses (#93507) are compact and lightweight. It is under three inches long, weighing in at 4 ounces.The Ultima Series Barlow (2x - 1¼") is an air-spaced, three element apochromatic design with a 27mm clear aperture. This lens features a very high quality, fully multicoated design. Amazingly compact and lightweight, it's just 5 ounces and 2.75" in length.

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.
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’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.
Britain’s most famous street to relocate to Salford Quays after ITV resumes development talks Britain’s most famous street is to be demolished. Coronation Street’s outdoor set, including the Rovers Return Inn, will move from Quay Street in Manchester city centre to a site near Manchester United’s Old Trafford stadium after ITV resumed talks to relocate its offices. Following the appointment of new ITV chairman Archie Norman, negotiations have begun again to relocate the soap’s famous pub and cobbled streets to the £600m Media City UK in Salford Quays. The existing site has been the setting for some of the most memorable scenes in television history, including numerous arguments between Ena Sharples and Elsie Tanner. With the advent of high-definition television, producers are keen to update the set as the new technology makes it easier to spot worn-out sets. Tracey Barlow, the fictional daughter of the soap’s most enduring resident, Ken Barlow, murdered her boyfriend Charlie Stubbs on…

Probably not that exciting for you!
well, that's tough. I just listened to most of the song. the easiest vocal harmony to do is a 3rd above. So if you play a C on a piano, then play an E, the E is your third above harmony. Then if you keep your fingers spaced apart like that, and keep moving up and down the keyboard, you can hear how the third above follows the root note. So if you play a D the third above is F, and if you play an A the third above is high C. got it? Now play C,D,E while singing an E,F,G, you're singing 3rd above! There are other notes that sound good in vocal harmonies, like a 5th above is rather spooky. I think in the beginning of 'never alone' the backup singer is doing a 5th (or 4th) below, and just staying on the same note while the lead singer continues the changing melody. That kind of thing is more advanced. Work on 3rd above, you should be able to sing along with the song doing 3rd above harmony. it will sometimes sound wrong any time the song shifts to a minor or other strange key, and when it does, find a different note that sound right to replace it, then go back to 3rd above, and then memorize your new 'harmony part' so you can sing it even without listening to the main melody. That's how you can rehearse. You could have something pretty good sounding by Saturday that way.
Neither lens would be considered a good sports lens. When you say indoor sports, one has to think of a fast telephoto lens.
I use a 24-70 mm f/2.8 and 200 mm f/2 for court sports and a 400 mm f/2.8 and 600 mm f/4 when shooting MLB and NFL.
After you look at the investment necessary to have those lenses in your system, think of this.
Get the 18-55 mm VR that comes with your D60 and also the 55-200 mm VR that is available and just shoot at an elevated ISO. A little noise in the image is much preferred to blur caused by subject movement

Man,I’d love to demo a 14″ EdgeHD that just might make me chuck my LX200 10″ Classic!

First of all, this is a terrible place to ask a technical question like this. 99% of the people here wouldn't know which end of a telescope to look through, let alone what a Barlow or a Powermate is. Try one of the Yahoo technical forums instead for reliable information.
The information the others have given you is accurate. I'd only add one point: there is a significant difference between how a Barlow and a Powermate operates. With a Barlow, if you add an extension tube between Barlow and telescope, you increase the magnification. Not so with a Powermate. The magnification stays the same or even goes down. Take a look at the graphs on the Tele Vue web site. My personal preference is for the Powermate, as it is a modern design and controls aberrations much better than a Barlow.
miiisababy asked: Yepp, I guess one of the better canon lens for that is 50mm f/1.8 and its only about $100….
You might stand more chance on FriendsReunited or Facebook. That way you can actually search for them and/or they may look for you.
I would have thought that the chances of anyone you knew stumbling across this question in the few days it will be open are quite low.
what musical amazing-ness!!! this is a beautiful piece!!
