Product Description

From the Manufacturer

Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. Celestron's filters are made of high quality, solid plane parallel glass with excellent homogeneity. They're anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit Celestron's, and most other manufacturer's, 1.25 inch eyepieces, and offer a full 26 mm clear aperture.

Celestron color filters are mounted in black anodized aluminum cells with the Kodak Wratten Series Number individually engraved, and come available in 4 assorted kits packed in plastic cases. The cells of each filter are double-threaded, so they can be stacked (piggybacked) in various combinations. This allows you to create different color combinations and transmission characteristics, or to have the same color characteristic, but with a lower transmission. When stacking color filters, the effective transmission of the combination you create is equal to the product of the spectral transmission of each of the filters used.

The effectiveness of the filters depends on several factors, including: the aperture and focal length of the telescope, the magnification being used, and seeing conditions.

4.0 out of 5 stars Good? Better? Best?, March 19, 2010

This review is from: Celestron 94119-10 1.25 " Eyepiece Filter Set (Electronics)

I purchased this set about a month ago, and must first say that the picture included does not represent the actual colors of this set, which are much more vibrant, not muted as it may appear. Contruction is very good for the most part, I gave the product 4 stars instead of 5 because the yellow filter glass is slightly loose within its metal frame, and hence makes a bit of noise as it shakes around. Certainly doesn't affect usage, and is completely unnoticable when inserted into an eyepiece or diagonal. The threading on all 4 filters was smooth, and easily screws into a wide range of products, not only those made by Celestron. On a good better best scale, I would put these in the better range. Certainly better than some bargain filters, but also no Lumicon.

I would certainly recommend this set to anybody. It is high quality offered at an excellent price. A similar set offered by Orion at the time of purchase was more expensive.

I aimed to review the construction and quality of this product, rather than provide an actual observational review. People buying astronomical filters already know what they are looking for.

These are great filters for viewing the planets and the moon. The only thing is that some of the filters are loose so they rattle this is pretty simple to fix. First thing you have to do to tighten the filter is set it down so the silver ring is up. If you look at the top of the filter you will see there is a plastic ring inside with two notches on it. You then just have to put a screwdriver or your fingernail into one of those notches and rotate the ring so it screws down into the filter, and this should stop the rattling.

I liked these filters. I've mostly used them for viewing the moon. They appear to be very good quality for the price.
