Product Info
Manufacturer Description
Color filters can be very useful for enhancing your views of the Moon and the planets. Depending on the atmospheric conditions, the telescope being used, the observer's experience, and the planet being observed or photographed, the advantages of color filters can be anywhere from subtle to dramatic. The right filter can make all the difference between seeing several small craters in the floor of Clavius on the Moon or not; seeing five or six swirls in Jupiter's belts or not; or seeing the inner Crepe Ring of Saturn or not.
GSO's 1.25" color/planetary filters are manufactured from the purest optical glass and are dyed-in-the-mass (not simply "color coated") for premium performance. They thread into the barrels of virtually any 1.25" telescope eyepiece. Each filter cell has a male and female 1.25" filter thread (M28.5x0.6) on opposite sides, so multiple filters can be stacked to achieve selective filtration of the visual color spectrum. The clear aperture is 25.6mm and each filter comes in a protective plastic storage case. Made in Taiwan.
The #82A Light Blue Filter enhances areas of low contrast while avoiding reduction of the overall brightness at the same time. It thus rivals the #80A Blue in popularity, being useful on the Moon, Mars, Jupiter, and Saturn. On the Moon it brings out surface detail; on Mars it is very useful during the violet clearing for studying the polar caps and the surface, while on Jupiter and Saturn it emphasizes the transitions between the various belts. Its use on Mercury and Venus gives results similar to #80A.
It has even been reported useful for bright galaxies, particularly face-on spirals such as the M51. The galactic structure, such as detail in the spiral arms, is more pronounced with the filter. Also, try this one to split binaries. It also enables viewing of cometary gas tails. The light blue filter is also a useful filter to stack along with other filters.

Planetary filter
Pros: Cons: Comments:I brought the filter in hopes it would enhance the spiral structures around galaxies. It worked especially well on M51 where the spiral arms were enhanced.

Oct 6, 2017Good quality filter at a reasonable price.
Pros: Cons: Comments:I really like these filters. They are a little lighter than Celestron filters, (about .08 grams) which may seem negligible, but it's noticeable in the hand. They also thread on very smoothly. Overall, the quality seems good and with all the overpriced options out there these GSO filters are a great choice. This #82A light blue is my go-to planetary filter in my 90mm refractor and 90mm Mak.

Oct 13, 2015If I only had one filter to use......
Pros: Cons: Comments:It is my "go-to" filter for my 90mm f5.6 Achro refractor. It enhances subtle details on the moon and planets without dimming the image. It's great to use for splitting close, bright double stars. It actually helps mitigate CA associated with Achros. Anyone who cannot see a difference when using this filter needs to spend more time at the eyepiece and learn how to observe rather than look. At this price, it is one of the best values in Astronomy! How can you not love this filter?

Mar 25, 2010GSO Light Blue
Pros:Accurate,Strong Construction,Compact,Quality Lenses
Cons: Comments:Great for bringing out detail on Jupiter, Mars, and the Moon. The color does not impose itself as much on the image as some other colors. I also recommend trying it out on a cluster or two. I know most folks don't recommend filters for these, but ON SOME CLUSTERS, the light blue seems to bring out a bit more texture to the image. It's light color keeps it from excessively darkening the target too much.
Bottom Line: Would you recommend this item? Yes
