With the 9mm 120°, however, you see even more universal real estate, but you also see the main attraction, whether it is a nebulae, a galaxy, or a star cluster, close up and personal.

Common solutions to this can be expensive and include the purchase of a monochrome camera, various types of narrowband filters, and a filter wheel. Especially with inexpensive Newtonian telescopes, double-lens ED refractors or even achromatic lenses, the L-eNhance filters open up completely new possibilities for taking high-quality astronomical photos, even from the bright city. CMOS cameras can even deliver images almost like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the city with all its artificial light sources.

We believe that the design of our L-eNhance filter represents a technical innovation among filters. It effectively isolates the H-Alpha, H-Beta and Oxygen-III fog emission lines and achieves a maximum transmission of up to 90%.

The Explore Scientific S-II nebula filter blocks all other colors (and thus almost all artificial light) and only lets through the emission lines of the ionized sulfur at 672 nm.

Common solutions to this can be expensive and include the purchase of a monochrome camera, various types of narrowband filters, and a filter wheel. Especially with inexpensive Newtonian telescopes, double-lens ED refractors or even achromatic lenses, the L-Pro filters open up completely new possibilities for taking high-quality astronomical photos even from the bright city. CMOS cameras can even deliver images almost like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the city with all its artificial light sources. L-Pro is a multi-bandpass filter that offers a better color balance by expanding the transmission range. The balanced transmission enables astrophotos with minimal color cast for broadband emission objects such as galaxies, reflection nebulae and globular star clusters. L-Pro is the first choice for light pollution suppression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Pro description \u003cbr\u003e\u003c\/strong\u003eThe L-Pro (L-Professional) filter was developed to improve the visibility of various deep sky objects. It selectively reduces the transmission of the wavelengths of light pollution, especially that of artificial lighting such as mercury vapor lamps, high and low-pressure sodium vapor lamps and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. Skyglow). Together with the high transmission in the main emission lines of the nebula at OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) and SII (672nm), this filter is suitable for the contrast and improve details for both visual and photographic purposes in rural areas with high levels of light pollution. L-Pro is a multi-bandpass filter, which offers a better color balance by optimizing the transmission band. The balanced transmission enables astrophotos with minimal color cast for broadband emission objects such as galaxies, reflection nebulae and globular star clusters. L-Pro is the best choice for light pollution suppression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain uses and performance\u003c\/strong\u003e \u003cbr\u003eSuitable for visual observation and astrophotography. The L-Pro filter has a very low transmission loss for celestial objects with a uniform spectrum and is therefore very effective in suppressing light pollution sources, such as in photography of galaxies, reflection nebulae and globular clusters. The same goes for visual stargazing. The L-Pro filter alone suppresses infrared wavelengths and can therefore be used for '' L '' images with CCDs without any problems. Light pollution filters do not remove the effects of light pollution or increase the brightness of the object. In many cases they simply increase the contrast between the fog and the night sky, but not the brightness of the fog itself.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e \u003cem\u003eThese nebulae filters are not suitable for solar observation.

This reduced weight enables use with lighter equatorial mounts like the Losmandy G11 PMC-Eight, offering greater flexibility without sacrificing performance.\u003cbr\u003e\u003cbr\u003eThe ED152 offers a 44% increase in light-gathering capability compared to the ED127, and 125% more than the ED102, providing exceptional brightness and resolution for observing planets, lunar features, deep-sky objects, and more. Its unobstructed design and precision coatings deliver images with stunning contrast, revealing fine details in nebulae, galaxies, and planetary atmospheres with remarkable clarity—even under suboptimal seeing conditions. Whether for research, outreach, or serious personal observing, this carbon fiber version of the ED152 is a highly capable and efficient instrument ready for demanding tasks.\u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":51270921912605,"sku":"TED15208CF-HEX33","price":3999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0059\/0158\/2449\/files\/vwb_888202f9-6680-47f4-a3f1-5a4f763e8431.jpg?v=1778528680"},{"product_id":"3-inch-self-centering-focuser","title":"3-inch Self-Centering Focuser","description":"\u003c!--start tab--\u003e\n\u003cp\u003eWith its ability to support heavy imaging trains without sacrificing stability, precision or smooth rotation, the robust Explore Scientific 3-inch Self-Centering Focuser is designed to meet the demanding requirements of astrophotography.\u003c\/p\u003e\n\u003cp\u003eThis heavy-duty focuser has a self-centering compression system that applies pressure equally to the draw tube, guaranteeing a tight, secure fit. This uniform pressure creates a stable base for an imaging setup and prevents flex, tilt and image shift. The draw tube, which is long enough to eliminate the need for extension tubes, is moved by a helical rack-and-pinion system lubricated with marine-grade PTFE silicone for an easy glide with maximum precision and minimal backlash. The interior of the draw tube has a diameter of 3 inches that is lined with multiple baffles to reduce reflection.\u003c\/p\u003e\n\u003cp\u003eThe draw tube, which has a travel of 84.5mm, is supported by a locking clutch system. The focusing system has a lifting capacity of 17 pounds. Moderate tightening offers an infinite range of tension to best suit the application.\u003c\/p\u003e\n\u003cp\u003eWeighing in at 5.7 pounds, the focuser is made of black anodized aluminum. It has a 9:1 focus system with stainless-steel ball bearings and stainless-steel focus shaft. This system works as a clutch to prevent damage to the focusing mechanism. The focusing system is compatible with popular after-market electric focuser devices.\u003c\/p\u003e\n\u003cp\u003eA back cell adapter with no-tool knobs attaches the focuser at four contact points to select Explore Scientific refractors with apertures ranging from 120mm to 140mm. The knobs on the adapter can be hand turned, eliminating the need for a hex key. This makes it easy to adjust the rotation of the focuser with minimal observing or imaging interruption. A Teflon ring on the focuser adds to the smooth rotation.\u003c\/p\u003e\n\u003cp\u003eFor versatility, the focuser can hold 2-inch or 3-inch visual or camera accessories and comes standard with twist-lock. In addition to allowing accessories to be secured with a compression fitting, this draw tube’s M82 x 1.25 pitch thread accepts adapters with a variety of uses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE: Explore Scientific white-tube telescopes with threaded back cells\u003c\/strong\u003e\u003cstrong\u003e \u003cspan style=\"text-decoration: underline;\"\u003eMUST BE SHIPPED to Explore Scientific\u003c\/span\u003e for installation of the back cell adapter.

At this focal length, this eyepiece is generally reserved for deep sky observers who challenge themselves to observe near the faintest observable limit of their telescopes.
