Apertura 2" Moon and Skyglow Filters - Set of Two
If you're tired of light pollution wreaking havoc on the views through your binoculars, Apertura has you covered! The Apertura 2" Moon and Skyglow Filter Set gives you a pair of filters to reduce the effects of light pollution while increasing contrast through your binocular eyepieces. These block out light from surrounding street lights, house lights, and other forms of artificial light pollution, as well as tackling natural light pollution from the Moon. The gentle, yet targeted filtering combats these contrast lowering elements while leaving the light from many stellar objects untouched, for an elevated observing experience.
As opposed to aggressive light pollution filters such as UHC filters, the Apertura Moon & Skyglow filter set takes a gentler approach, increasing contrast yet still producing natural, more pleasing colors. This makes it useful for observing bright objects such as the planets, star clusters, and even some nebulae. Adding this filter to your binoculars can reveal higher definition and subtle improvements on celestial objects. More aggressive light pollution filters can offer increased contrast when viewing many faint nebulae, although these types of filters tend to darken the sky too much when using higher magnifications. The gentler nature of this Apertura Moon & Skyglow filter will provide a more natural looking sky background with more stars revealed. As such, moon and skyglow filters are generally thought of as “all purpose” filters and viewed as being beneficial on a broader range of objects. With this versatility and the exceptional build quality from Apertura, you’re sure to be out under the stars as much as possible!
Emphasize Detail and Improve Contrast With This High Performance Filter
Let's Take a Deeper Look!
What sets one filter apart from another? Which filter is best for me? When developing a filter, manufacturers provide a chart that represents the wavelengths permitted through this filter. This gives insight into the filter’s performance, and what it can help you achieve. So, how exactly do I read a transmission chart? Our team has put together a comprehensive article, to help you understand the fundamentals on How to Read a Transmission Chart. Check out the article and feel more confident about choosing the right filter for your needs!
Better Definition and Higher Contrast - Elevate Your Visual Experience
With its specialized construction and precision coatings, these filters allow you to go beyond the constraints of light pollution, providing enhanced views of numerous celestial objects. Read more about these incredible filters below!
More Detail, Less Light Pollution
During the day, light from our Sun illuminates our atmosphere, concealing the stars, planets, and other celestial bodies from view. Artificial light and moonlight can have a similar effect on our atmosphere, which is why it’s difficult to discern details from astronomical objects under bright Moon light or within urban areas. By cutting through light pollution with the Apertura Moon & Skyglow Filter set, more details can be resolved that may have otherwise been much tougher to see! The Apertura Moon & Skyglow filter blocks out a wide band of wavelengths to improve contrast. As such, these inherent light blocking abilities means filter stacking is not recommended with this accessory.
Compatible With Almost Any System
These Apertura 2” Moon & Skyglow Filters are mounted within sturdy filter cells, and seamlessly incorporates into your binocular set up for high contrast views. These cells are designed to the 2" filter standard, for threading onto filter compatible binoculars & constellation binoculars or into 2" eyepieces in big interchangeable eyepiece setups. These filters have been optimized for an exit pupil of 2mm or larger when viewing the fainter deep sky targets.
Built With Quality in Mind
Apertura is known for their high caliber craftsmanship, and their Moon & Skyglow Filters are no exception. Schott B270 glass coupled with precision Ion Assisted Deposition (IAD) coatings deliver the utmost transmission in the desired wavelengths by reducing scatter and upholding its durability. Also, these coatings feature off-band blocking to further enhance the light pollution suppression performance. With a featured Surface Quality of 60/40 and Surface Flatness of λ/4, maximum clarity can be seen within your eyepiece.
