Celestron 94105 Neutral Density Moon Filter - Compatible with 1.25" Eyepieces and Suitable for Lunar, Venus & Double Star Observation, Black

great product. Gives great contrast on observating.

The filter is what I need as a standard moon filter left the moon too bright when viewing it through an 8” telescope. I do wish the filter had markings on the side to indicate how dark I am setting the filter but I’m fine without it. It’s a good filter though overall.

This filter isn't going to change your life, but if you have a super bright full moon or super powerful telescope, it can definitely help for some casual moon watching. I could see many more moon craters with this. I'm glad I bought it and had it for the recent supermoon event. It made viewing a bit easier, but for photography it wasn't really required as it is a neutral density attenuation of the light and that's exactly what your camera will do when it changes exposure time to a shorter exposure. Let me sum it up this way, I'm glad I have it and if I lost it, i would probably buy it again.

You can tell a pretty large difference between the amount of light reaching your eye using this piece. The full moon is still to bright to edge in all those details but it will take away some eye strain. As far as using it for photography, you will have to adjust coloring to get out the green tint. If you use lightroom, adjusting the temp to -5 and the hue to 5 will give you a kind of natural bluish tint. As I stated before the full moon is still a light pollution monster so your camera may do it better justice adjusting the ISO or frame speed. Maybe ISO 80 and 1/125 fs. But if you're looking at a Waning Gibbous this filter will help manage the ambiance so you can see those craters hiding off to the edge in the shadows. Pretty good for it's price. It also fits in both my celestron eye pieces and pylossl which is nice. Can switch between my newtonian reflector and celestron refractor without to much eyepiece play. I don't recommend for stargazing or looking for planets unless you're using a high power piece

Good moon filter.

I bought this as an accessory to my new telescope after watching a youtube video on why you might need a moon filter. Waxing Gib moon @ 98% brightness tonight, so I took it out and gave it a whirl. It works as advertised! It cut down the glare from the moon allowing better definition of the craters. The image was crystal clear, just tainted a slight bit green. The filter simply threads on the forward part of the 1.25" eyepiece and then you slip the eyepiece in the telescope. I tried viewing the moon with and without the filter, and I definitely prefer using the filter. I highly recommend it and the price certainly won't break the bank.

I haven't even tested this product out with the upcoming "supermoon" on Aug. 31 2023, but I was disappointed from the "git-go" upon opening. Didn't even come with a small plastic case that might have added $0.25 to the total cost of the product. It came in a small cardboard box, wrapped in tissue paper and a tiny zip-seal bag. Disappointed by the cheapness of the manufacturer

This filter makes the Moon look better, dimming it as well as increasing contrast. The image is clear.

Reduce bastante el brillo, fácil de instalar y buena calidad

First class filter forviewing glaring moon

Enseñar la luna con telescopio es un gran evento para niños a partir de 3 o 4 años, sin embargo al concentrase la luz en la óptica puede dañar la retina del niño. Este filtro lunar es adecuado, pues reduce un 87% la luminosidad y además no cambia el color, con lo que el niño se queda con un recuerdo "realk" y no coloreado. Yo lo compré para mi hijo y sus amigos y solo les muestro la luna cuando está en fase, nunca luna llena, con luminosidad inferior al 60% y le dejo mirar en periodos cortos de 5 segundos. Para mi es una pieza imprescindible por seguridad del niño. El precio es adecuado y la marca está especializada en telescopios y filtros. Totalmente recomendable.

Buen filtro polarizado. Me gustó que puedes variar la cantidad de luz que entra a tu ocular, funciona perfectamente para observación lunar y planetaria, sobretodo que ofrece mejores detalles de planetas muy brillantes como Marte o Jupiter. La luna llena ya no me quema los ojos con este filtro, lo único malo es que hay que hacer pruebas quitándolo y poniéndolo para dejarlo con el nivel de entrada de luz deseado.

La presentación desde el empaque es muy buena, y el filtro se ve de calidad.
