4.0 out of 5 stars Simple little thing, but essential, 2 Feb. 2012
Verified Purchase(What is this?)
This review is from: Celestron Moon Filter (Camera)
First impressions aren't good... The filter arrives in a padded envelope, inside which there is a flattened plain white box featuring a Celestron label, containing a ziploc plastic bag with the filter within. The delivery note advises that this is "eco packaging", and to be fair the filter itself is undamaged.

Your money buys you a small plastic disc, an opaque core surrounded by a black border with the word "moon" on one side. The rear of the disc has screw threads, and what you have to do (the filter comes with no instructions) is simple: 1) screw it into the bottom of your chosen eyepiece for your telescope, 2) put the eyepiece into the focus tube, 3) look through it.

So does it work? Without the filter if I look at the Moon through my Celestron Astromaster 130EQ using the standard eyepiece the Moon appears rather too brightly to identify features, and after a few seconds I feel the need to look away, as though I've been looking at a light. With the filter the difference is incredible, the contrast improved and the light dimmed comfortably, and I can now see the rims of craters on the Moon, plus if I look at Jupiter I can just about make out cloud systems on the surface if I focus carefully.

For such a small, cheap, flimsy-looking thing it makes an incredible difference. An essential item for the budding astronomer.
