This is not a conventional telescope filter but instead is an adapter to mount your smartphone on your telescope. So, in summary, the main features of this moon filter by Orion include that it: reduces glare, is able to fit directly on the 1.25 inch eyepiece of the instrument, allows only 13 percent of light to pass through to boost contrast, and does not alter the color of the moon due to its neutral color.Īll these features make it one of the best filters of 2019. The Orion neutral density eyepiece filter also helps in conserving dark-adapted vision while viewing the moon. Irradiation is the drop in image quality at the boundary between light and dark areas, this eyepiece filter helps in reducing irradiation as well.
This Orion Moon filter is special because it does not alter the color while reducing overall brightness. It helps in canceling out almost 87 percent of light gathered by the telescope, providing a clearer view with higher contrast.ĭue to this higher contrast provided by the 1.25 inch 13 percent transmission moon filter, the astronomer is able to do a detailed study of the moon. It improves the image quality by fitting directly to the 1.25-inch eyepiece of the telescope. One of the best telescope filters is the Orion 1.25 inch 13 percent transmission moon filter because it helps considerably in decreasing the glare and improving contrast. This article reveals the best telescopic filters available in market for your convenience. There is a variety of filters available in the market, and they all have different functions. Telescope filters can bring a huge difference in image quality, they significantly improve the view and help the astronomer in numerous ways. In the same way, air pollution like dust particles and smog can produce blurred images through the telescope. This light creates a glaring effect that stops the astronomer from getting a clear view. People living in cities are always surrounded by light. These factors include light pollution, air pollution such as smog and dust particles, the glare of sunlight on these stars/planets, etc. But many factors hinder clear viewing of these celestial bodies either by the naked eye or through the telescope. Since this study cannot be done with the naked eye, astronomers take help from telescopes to view the universe properly. Astronomy is said to be the study of celestial objects and phenomena outside the Earth's atmosphere.
