The T2 17 2 inch Deluxe Clamping Eyepiece Holder incorporates dual oversized stainless thumbscrews plus a captive spring bronze clamp ring to protect your eyepiece and accessory barrels from damage. The inclusion of two clamp screws results in a superior 3 point attachment that completely constrains your equipment from wobble particularly important for imaging applications (all typical single clamp screw adapters still allow some motion). Also for those users that are physically unable to firmly grasp and tighten lock screws the addition of a second screw doubles the locking force (ie particularly nice for those unable to grip tightly due to arthritis). The holder is precisely machined to fit your eyepieces with a minimum of slop resulting in a close accurate fit that keeps your eyepiece properly centered on the optical axis. For attachment the holder is provided with an internal 2 inch thread the same thread used on the back plates of all SCT telescopes. This permits the holder to be directly threaded onto SCTs delivering the widest views possible. Capture the moment!  Celestron's T adapter for Schmidt Cassegrain telescopes will allow you to attach a 35mm SLR camera to your telescope. Celestron's T adapter threads onto any SCT's rear cell and works seamlessly with a T ring made specifically for your brand of camera (sold separately). It expands the utility of both camera and telescope. With it you'll capture the moment indeed   up close! Premium performer!     PowerSeeker telescopes are a great way to open up the wonders of the universe to the young astronomer!

Some of the world's most elite telescope manufacturers would not use anything but the best and choose the Feather Touch Focuser for their stock focusers.  Many serious astrophotography enthusiasts that use telescopes without a Feather Touch Focuser will immediately change their focuser to a Feather Touch.     For achieving perfect focus you need a focuser that is smooth as can be.  With ultra fine detail adjustment.  Only the Starlight Instruments Feather Touch focusers can offer such perfection.     Simple to install yourself and can be completed in 10 minutes.  Detailed Instruction included. Much more than a simple minus violet filter. Based on the popular Baader Moon&Skyglow filter the Baader Contrast Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surround and smear resolution and contrast. Subtle contrasts and colors are boosted while displaying the full resolution your scope is capable of.  The Contrast Booster combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long pass blocker on one face and a 7 layer ultra low antireflection coating on the other face. By aggressively filtering out the defocused blue wavelengths a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum. This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter without excessive image dimming. Cloud bands retain their ruddy red hues but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunarscapes are set against a jet black sky. The Contrast Booster is a must for Solar observing (with Baader Astro Solar).  As many users have found this is the ideal filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking.  Combined with the Baader UV IR Cut Filter the Contrast Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging) the Baader Contrast Booster has been optimized for visual use. Digital imagers can simply add our Baader UV IR Cut Filter when ne Celestron PowerSeeker telescopes are a great way to open up the wonders of the Universe to the aspiring astronomer.

    Celestron's deluxe tele extender is a high power photographic accessory for Schmidt Cassegrain telescopes. It's 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 telescope's effective focal length to well over 10000mm! And with this comes a corresponding increase in image size.  It's a technique known as eyepiece projection photography and it multiplies magnification by the distance from eyepiece center to the film plane according to the following formula: Effective Focal Length = Telescope focal length ? Eyepiece focal length X DF (distance to film).  The deluxe tele extender is used for high power lunar solar and planetary photography as well as for extreme terrestrial photography. To employ the 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 and attach your 35mm SLR camera to the back of the tele extender using a T ring. That puts you in business for fine highly magnified astrophotography!  Note: The image you'll see through your camera's viewfinder will be upside down. And because of the extremely high magnifying effect afforded by the deluxe tele extended you'll want to take extra care to prevent camera and telescope vibration. Accurate polar alignment and using only under good seeing conditions will also help you capture high quality images.  The deluxe tele extender is only for Schmidt Cassegrain telescopes!
