[edit] Modern Barlow lenses?

I have moved this edit to talk because does not cite a source and reads like an advertisment.

Modern Barlow lenses are usually good in quality. With the growing popularity of premium short focus apochromatic refractors, higher power barlows lens like 5x Tele Vue Powermate was introduced to the market to allow high power observation. These high power Barlows lenses contain more lens elements than traditional Barlows lens to minimize pupil abberation.

Please clean up if you are going to re-add it. thanks Fountains of Bryn Mawr 06:35, 2 February 2007 (UTC)

[edit] Recent removal

I took out the following passage:

Barlow lenses have an unfortunate reputation in some quarters due to poor results given by the Barlows included with some inexpensive telescopes. These results, however, are perhaps better attributed to poor optics and shaky mounts permitting less practical magnification in these telescopes than to an inherent failing of Barlow lenses.

While the entire article is uncited, this bothered me especially, since all the weasel-wording makes it sound like someone's OR. intooblv (talk) 20:56, 23 December 2007 (UTC)
