Celestron X-Cel LX 18mm - !.25 Inch Eyepiece.
on 17 June 2013
I chose the the 18mm eyepiece as it gives good magnification for deep sky objects such as galaxies and planetary nebulae. My new telescope is a Celestron NexStar SLT 127mm. It has a focal length of 1500mm, so the magnification is 1500 divided by 18 = 83 times. The eyepiece is much better than the two standard eyepieces that came with the scope, both in field size, ( difficult to judge as the two that came were 25 & 9 mm.)and also field clarity, ( more easily judged.) I live in the north of Scotland where we are blessed with little light polution, however at this time of year, June, the skies never get dark. Despite this the 18mm eyepiece works well at spliting double stars i was particularly pleased to split Polaris, it has a fairly wide seperation of 18.4 seconds of an arc but the primary is very bright 2.0, and the companion dim 9.0. As the experience has been so good i intend to buy the entire range of Celestron X-Cel eyepieces over the next few years, without going below 5mm, ( my telescopes 300 times magnification limit ) making the 12mm eyepiece my next purchace. Philips " Stargazing with a Telescope " by Robin Scagell, says : "Top of the accessories list is extra eyepieces." I recommend the 18mm X-Cel LX Eyepiece.
I bought the eyepiece from Amazon. It arrived promptly despite my remote UK location. Amazon are one off very few companies that do not add hefty postage charges to the Highlands and Islands of Scotland.
