ND (dimming) type.
Metal frame, made of optical glass.
I stored it in an unopened plastic case, and it was kept in a paper box and not exposed to light, so I don't think the coating will deteriorate due to moisture or light.There are internal threads (female) and external threads (male) on both sides that can be used to stack multiple filters.Bright planets other than the moon are also possible. For viewing, taking photos, and for both purposes.
I think it's also good for CCD cameras, you can use it.If you attach filters in advance to the long focal length, low magnification Ibis and the short focal length, high magnification filter, you can change the magnification without any hassle. As the magnification increases, the field of view becomes darker. If you stack two filters, the transmittance will be 1.69% (0.13X0.13).Mounting eyepiece (internal thread on the telescope insertion (sleeve) side, if necessary, there are no pitch differences depending on the manufacturer, and the pitch is standardized) 31.7 mm (= 1.25 1 1/4 inch) size.
Specs are as described by the manufacturer.The last precious 100% before the production base was in China, the optical glass, metal frame, and coating are all made in Japan.In the image, the plastic packaging bag is cloudy. The filter is free of dust, dirt, and cloudiness.Never use it for sun gazing.24.5mm Mooglas is mainly designed for F=10 class or higher. With today's bright optical systems below F=8 and thick eyepieces, vignetting increases. The shorter the focal length, the larger the aperture, the smaller the F number (focal length of the objective lens, primary mirror/its effective aperture), the more this is necessary. It really hurts my eyes. It's scary to see people showing off at clubs and other parties without wearing anything. Even if you don't use this product, you can use computer glasses for gazing at the moon when it's older, so it's a good idea to wear them even for a short time. It's boring, but it's good to have one.
