This specialized filter allows high transmission of light from emission nebulae while blocking light pollution, helping to make your images pop with detail off the black sky background with superior contrast.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFortunately, many sources of light pollution have relatively discreet emission spectra; they emit primarily at specific wavelengths of light. By strategically blocking these “bad” wavelengths, the filter essentially eliminates the effect of light pollution while letting the “good” wavelengths of light associated with the emission nebula pass through to the camera. You’ll notice much higher contrast in your images immediately, even if imaging from your light polluted backyard! And since the transmission at the key wavelengths is so high, the nebula will not be dimmed—only the background will be blacker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003e\u003cbr\u003e\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eNebula Hunting\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Hα-Hβ-OIII Imaging Filter for the 8” RASA is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), and the Carina Nebula (NGC 3372). The imaging filter transmits key Hα-Hβ-OIII wavelengths that produce high contrast for emission nebulae.\u003c\/p\u003e\n\u003cp\u003eThe transmission spectrum for the Hα-Hβ-OIII Imaging Filter is 85% or greater at key wavelengths (486nm, 496nm\/501nm, 656nm) and less than 0.5% transmission elsewhere. The Hα-Hβ-OIII Imaging Filter for the 8” RASA is a narrowband filter that blocks much of the visible spectrum and only lets specific wavelengths through. Because of this, it will not work well on broadband emission objects, such as galaxies and star clusters.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/93619_H_-H_-OIII_Imaging_Filter_RASA_8_04_480x480.jpg?v=1618006550\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eOther similar imaging filters on the market have much narrower bandpasses at the critical Hα-Hβ-OIII wavelengths, but these filters will actually block much of the incoming Hα-Hβ-OIII light for an F\/2 optical system. This is because the light is coming into the filter at a steeper angle, which causes a spectral shift. Using filters not designed specifically for use at F\/2 will cause some of the light from the nebula to be blocked, resulting in a dimmer image. The Celestron Hα-Hβ-OIII Imaging Filter for the RASA 8 was custom engineered to work at F\/2, so none of the “good” light from the nebula is inadvertently blocked by the filter.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eBody and Storage\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe filter is machined aluminum black anodized cell with knurled rim for easy grip during installation.  An anti-reflection coating has been added to the filter to help suppress reflections on the glass. The filter fits directly into the internal filter mount in the RASA 8’s front lens cell, where the optical window normally mounts. By removing the clear window and replacing it with the filter, optical performance for the entire system is maintained. No other adapter is needed.\u003c\/p\u003e\n\u003cp\u003eEach filter comes with a foam-lined plastic storage case and retaining ring to safely store the filter or the placeholder optical window glass that came with your RASA when not in use.

Upgrade your existing star diagonal to this premium one and enjoy brighter, sharper images without purchasing an entirely new telescope. \u003c\/p\u003e\n\u003cp\u003eThis star diagonal reflects the telescope’s light path 90° to provide a more comfortable viewing angle. In addition, the glass has 58 layers of dielectric coatings, which provide an over 99% reflective surface, delivering the maximum amount of light to the eyepiece. This 2” star diagonal has the added benefit of allowing you to use larger 2” eyepieces with your telescope, providing a wider field of view, or standard 1.25” eyepieces with the stepdown adapter. \u003c\/p\u003e\n\u003cp\u003eThe twist-lock eyepiece holder secures eyepieces while keeping them centered in the diagonal, thus providing best opto-mechanical alignment between the telescope and eyepiece. Unlike traditional thumb screws, the twist-lock cannot scratch or engrave the barrel of your eyepieces. The diagonal has an integrated 2” barrel stop that prevents 2” accessories with long barrels from damaging the mirror. \u003c\/p\u003e\n\u003cp\u003eAll the diagonal’s mechanical parts are made of machined black anodized aluminum, except the twist lock rings, which are orange anodized for visibility. The interior of the Schmidt-Cassegrain adapter and 2” barrel are glare threaded and painted flat black to prevent glare. With all its features and these high-end finishes, the Celestron Dielectric Star Diagonal, 2” with Twist-Lock is one of the highest quality 2\" star diagonals that Celestron has ever offered.\u003c\/p\u003e\n\u003cp\u003eThis diagonal also comes with two interchangeable barrels to provide flexibility in connecting the diagonal to a wide variety of telescopes without the need for additional adapters. For telescopes, like refractors, which accept 2” barrels in their focuser, a standard 2” barrel is included. For Schmidt-Cassegrains (SCTs) that use a threaded connection to the focuser, a barrel with SCT threads is included. Both barrels thread onto the diagonal housing, providing a secure connection to the diagonal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Star Diagonals vs Dielectric Star Diagonal \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe key specifications for a star diagonal are its reflectivity and its optical quality. This diagonal delivers top performance in both categories, with an over 99% reflective mirror and diffraction-limited optical quality. This ensures that virtually all the light collected by the telescope will reach the eyepiece without the diagonal affecting optical performance. Using a lower quality star diagonal can both dim the view and degrade optical quality. You can enjoy better views from your telescope by simply swapping out its diagonal for a premium one, like the Celestron Dielectric Star Diagonal.\u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":46382032781569,"sku":"93573-CGL","price":233.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/6857\/8817\/files\/93573_Twist-Lock_Dielectric_Star_Diagonal_2inch_01.jpg?v=1749502538"},{"product_id":"omni-2x-barlow-lens-125in","title":"Omni 2x Barlow Lens - 1.25\"","description":"\u003cp\u003eA Barlow lens is the astronomy accessory that keeps on giving!

All of the planetary filters included in the 1.25” Eyepiece \u0026amp; Accessory Kit, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.\u003c\/p\u003e\n\u003cp\u003eThe Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it blocks enough glare so you can observe the planet’s phases more easily.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eMetal Case\u003c\/em\u003e: The sturdy metal carry case has die-cut foam inside to protect and cushion your accessories. Store each one in its appointed place when not in use and you’ll keep them looking and performing like new. The case is even large enough to carry a few extra accessories. Just pull out enough of the foam cubes to make a nest for your eyepiece, camera adapter, etc. A tight fit is better, so remove the least amount of foam possible before testing the fit.
