Celestron Solar Filters are made with Baader Astro Solar Safety Film. Far superior than any existing glass, Mylar or polymer filters, they lead to brighter, sharper, and higher contrast images. Enter the new 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 previously manufactured high quality, plane-parallel glass solar filters (unlike today ?s glass filters which generally are poor in quality with reduced contrast). Celestron has offered Mylar solar filters (they were the best previously available) but they suffer from a lot of scattered light and false color. Polymer filters suffer from not only scattered light but also have reduced sharpness and contrast due to their increased thickness. So, ?we?ve been there and done that? and after all these years are now offering the finest solar
Celestron NexStar 114GT Specifications **Brightness Rating of 3.5 **Limiting Stellar Magnitude of 12 -- **114mm (4.5") Reflector -- **1000mm f/9 Focal Length -- **Star Pointer Finderscope -- **Motorized Altazimuth Mount -- **25mm SMA (40x) and 10mm SMA (100x) Eyepieces -- **Accessory Tray -- **Fully Computerized -- **4,000 Object Database -- **Assembled Weight: 15.5 lbs. -- The NexStar 114 Newtonian reflector has 265 times the light gathering power of the average human eye, revealing fine detail within galaxies and nebulae. This compact design brings objects into view with a 114mm aperture, 1000mm focal length capable of achieving magnifications of 40x and 100x with the included eyepieces. -- Its large 4.5" diameter outshines smaller scopes. Polar caps on Mars become visible along with the cloud belts on Jupiter. The rings of Saturn are clearly visible. Most exciting is the wide variety of deep sky objects (stars, clusters, nebulae). Because of their optical design, reflectors are best suited for astronomical use. -- All you need to know is the general direction of North, your closest major city (included in the instruction manual), plus the date and time, and you will be observing planets, stars and more within moments. -- NexStar computerized telescopes are so straightforward, astronomers at all levels can locate over 4,000 pre-programmed stars, planets, and other celestial objects right out of the box. Plus, fully assembled tripod ad pre-installed electronics make set up quick (taking only seconds) and simple. -- All of our NexStar Telescopes come equippped with 2- 1.25" eyepieces and everything you need including the hand controller. -- Limited Quantities Available - On Sale Now!
