I can delivery further afield but please contact to discuss personal delivery option before purchase. This is not for sale internationally!   Details from the web below: The Celestron C9.25” is already a favourite among astrophotographers and discerning visual observers and offers 33% more light gathering than the 8" model. The CPC 925 GPS was specifically designed for visual infinity focus when using 2" eyepieces and has an optimized baffle system to benefit astrophotography by minimizing vignetting at the edge of the field of view. Its longer primary focal length and lower magnification secondary mirror contribute to a flatter field of view at the focal plane and helps to further reduce optical aberrations.

Minimizes vignetting at the edge of the field of view. This reduces light drop off at the corners of your film plane.     •    Hand Figured Optics — Just like all other Celestron Schmidt-Cassegrain telescopes, the CPC 925 GPS optics are individually matched and hand figured to ensure the highest optical quality in every telescope.     •    Focus mechanism — At the heart of Celestron's Schmidt-Cassegrain focus mechanism are pre-loaded ball bearings, not bushings, minimizing focus shift.     •    Heavy-duty die cast aluminum fork arms —For maximum rigidity.     •    Unique roller bearing design bearing and shaft —The telescope base rotates around a wide 9.5” track for maximum stability; especially important when equatorially mounted for imaging.     •    Autoguider port — For interfacing an autoguider or a drive corrector for long exposure imaging or astrophotography.     •    StarBright XLT coatings — High quality multi-layer coatings maximize transmission of light to the film plane.  ..

    In very nice condition this reducer is perfect for those wishing to add a reducer to their Edge HD Details from the web: Celestron’s new EdgeHD reducers features a custom 4 element optical design engineered to maintain the flat-field performance of our award winning EdgeHD optical system. Unlike generic reducers, our premium reducers provide substantial back focus to accommodate an assortment of imaging accessories. EdgeHD reducers offer high index optical elements, including extra low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air to glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design. With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today. Performance Design: 4-element optical layout designed specifically for the EdgeHD 8" to maintain the flat-field performance of the Edge HD optical design 105mm of back focus: Provides generous back focus to accommodate additional accessories and a wide variety of cameras. Also allows use of existing T-adapters for EdgeHD 800 and other Celestron imaging accessories One full F-Stop faster than f/10: Reduces the exposure time by one-half to capture the same brightness of object Increase field of view by 43%: Better for capturing wide field images of larger galaxies and nebulae Glass Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration Fully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction Blacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast Full Frame Design Optimized for APS-C sized sensors: Including most DSLR cameras and Nightscape CCD cameras Mechanical Design Machined aluminum housing: Computer assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.

    In good used conditionManufacturer's product description:Visual and Photographical UseThere are many applications that require you to change between filters regularly. The usual way is to remove the camera or eyepiece from the telescope, unscrew the filter, screw in another filter, put everything back in the telescope and focus again. This procedure is annoyingly bothersome and takes a lot of time. The TS Optics Filter Quick Changer allows you to switch between filters within a few seconds without having to refocus after the filter chang.Examples of Use:Astro Imaging: LRGB colour imaging, narrowband colour imaging, use of different contrast filters and nebula filtersPlanet Observing: Ideal for using colour filters. The quick change between the filters allows you to directly compare the effect of different filters and thus choose the ideal filter for the particular application.Deep Sky Observing: You can directly compare the impressions with UHC filters, O-III filters and other filters. This allows you to get the most detail out of each object!Advantages of the Filter Quick Changer in comparison with other systems:There is no limit to the number of different filters you can use.Very low profileThis also results in best possible field illuminationThe filter quick changer needs less space than e.g. a filter wheelThe filters currently not in use can be stored protected from dew and dust. In classical filter drawers the filters are completely unprotected!..
