Key features Celestron
- Improved transmission translates to maximum image brightness and contrast. Users of smaller, 4"-11" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.
- The multi-layer dielectric coatings are plasma assisted and Ionbeam hardened using the latest technology for durability and resistance to scratching.
- The high transmission, sharp cutoffs, and more moderate 60nm passband of the UHC/LPR filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader bandpass and inclusion of an extremely efficient H-Alpha passband (656nm)
- Model: Celestron 2" UHC / LPR Filter
Review Celestron 2" UHC / LPR Filter / Celestron:Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i. e. sky glow). The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:. |

Key features Celestron 94175
- Four-element, fully multi-coated optical design with 41mm clear aperture
- Works with any brand and size of Schmidt-Cassegrain. Threads into rear cell.
- Shortens effective focal length of Schmidt-Cassegrain optical system by 37%
- Converts f/10 optical system to "faster" f/6.3 for a wider field of view
- Shortens exposure times for astrophotography by 2.5 times
- Model: Celestron f/6.3 Reducer Corrector for C Series Telescopes
Review Celestron f/6.3 Reducer Corrector for C Series Telescopes / Celestron 94175:This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9¼, C11 and C14 telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6. 3 for C5, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope. If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3. Celestron doesn't offer a f/6. 3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6. 3 Reducer/Corrector. [+]Results are amazing both visually and photographically. |

- Model: Celestron Deluxe Tele-extender for Nexstar Telescopes
Review Celestron Deluxe Tele-extender for Nexstar Telescopes / Celestron 93643:The Deluxe Tele-Extender for Schmidt-Cassegrain telescopes is a hollow tube that allows you to attach a camera to your telescope, with an eyepiece installed. By using the Deluxe Tele-Extender in combination with an eyepiece, you can increase your instrument's effective focal length to well over 10,000mm! And this corresponds with a matching increase in image size. This technique is known as eyepiece projection photography. The following formula can be used to determine approximate effective focal length:EFL = Telescope focal length/Eyepiece focal length x DF (the distance from the center of the eyepiece to the film). The Deluxe Tele-Extender is used for high-power lunar, solar and planetary photography as well as for extreme terrestrial photography. It fits over the telescope's eyepiece (even large eyepieces such as those in Celestron's Ultima line), and connects to the visual back of the telescope. Optional counterweights will be necessary to properly balance the telescope when using the Tele-Extender. To use the Deluxe Tele-Extender, remove the diagonal from your telescope and insert an eyepiece directly into the visual back. Place the Tele-Extender over both the eyepiece and the visual back, then attach your 35mm SLR camera to the back of the Tele-Extender, using a T-Ring. The Tele-Extender's built-in safety device will help prevent your eyepiece from becoming accidentally dislodged. [+]There are a few things to keep in mind when using this access. |

Far superior than any existing glass, Mylar or polymer filters, they lead to brighter, sharper, and higher contrast images. Enter the millennium with the finest solar filters available. Astro Solar Safety Film is clear and homogenous and attains the optical performance of high quality plane-parallel glass filters-it is diffraction limited! Double-sided metal coatings have uniform density and good color balance across the entire field ensuring razor sharp images from edge to edge. The Sun appears in its "real "color -neutral white, not blue or orange ,and the sky adjacent to the solar limb is jet black. You can see detail in sunspots, bright faculae near the limb and the mottled areas known as granules with these filters. The Sun offers constant changes and will keep your observing interesting and fun. Even small aperture telescopes can enjoy features of the Sun. The Astro Solar film is completely safe and durable (won't break like glass if dropped). Its rating is ND-5 which means that the film transmits 1/100,000 of visible light (. [+]001%) while reflecting (blocking) 99. 999%of unwanted light. The film absorbs all ultraviolet rays while coating reflects infrared light rendering both absolutely harmless. For added assurance, Baader Astro Solar film has been declared safe for direct solar viewing by the German National Bureau of Standards for eye safety. Celestron has previousl. |

Key features Tele Vue PMT5126
- Telecentric operation (field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays). This is ideal for Hydrogen-alpha filter use such as with Daystar models.
- High performance for image amplification, CCD or film (some of the finest Earth-based planetary imaging is being done with Powermates).
- Vignetting, edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces, are minimized.
- Latest Version, Accepets the T-Ring Adapter
- Flexible for visual and imaging with all types of telescopes and eyepieces. Essentially Parfocal, and with nearly constant magnification regardless of image distance behind top surface (except 5x model which increases 1x for every 35mm of image distance increase).
- Model: Tele Vue 5x Powermate Barlow lens 1.25" - T Ring Adaptable
Review Tele Vue 5x Powermate Barlow lens 1.25" - T Ring Adaptable / Tele Vue PMT5126:Tele Vue Barlows: "An Optically Perfect Window " Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. The 2. 5X Powermate Barlow is a 4-element parfocal, compact amplifying lens system. POWERMATE consists of a negative achromatic doublet plus a positive "pupil-correcting" doublet. While it looks and functions like a Barlow, your eyepiece will operate with pupil locations where the designer intended, avoiding mismatch problems. POEWRMATE optimally mates its power to your eyepieces. No additional "interface lens" is needed, since POWERMATES have it built-in. [+]In addition to full multi-coating, POWERMATE includes other Tele Vue special touches such as a safety undercut on the chrome barrell, and captive lock screws that can't fall out. Tele Vue's 100% QC program at f/4 insures that POWERMATE will add dramatic power (and NOTHING ELSE) to your favorite eyepieces. If, for example, you own a 22mm Panoptic, you'll have the power of an 8. 8mm focal length eyepiece with the 2. 5x POWERMATE. The POWERMATES are constructed to be parfocal with Tele Vue's 1-1/4" 90 degree diagonal (often used in Ranger telescopes) adding convenience not previously available with any Barlow. The 2. 5X POWERMATE has no filter threads Dobsonian/Ne. |
