and eyepiece housing rotate independently of the camera orientation making the acquisition of a guide star quite
easy. Second, the prism angle is tunable allowing you to look at guide stars on-axis. This accessory works
especially well with the Reducer/Corrector.
Reducer/Corrector (#94175) - This lens reduces the focal length of the telescope
by 37%, making your NexStar a 1280mm f/6.3 instrument. In addition, this unique
lens also corrects inherent aberrations to produce crisp images all the way across
the field when used visually. When used photographically, there is some
vignetting that produces a 26mm circular image on the processed film. It also
increases the field of view significantly and is ideal for wide-field, deep-space
viewing. It is also perfect for beginning prime focus, long-exposure astro
photography when used with the radial guider. It makes guiding easier and
exposures much shorter.
Sky Maps (#93722) - Celestron Sky Maps are the ideal teaching guide for
learning the night sky. You wouldn’t set off on a road trip without a road map, and you don’t need to try to
navigate the night sky without a map either. Even if you already know your way around the major constellations,
these maps can help you locate all kinds of fascinating objects.
Skylight Filter (#93621) - The Skylight Filter is used on the Celestron NexStar
telescope as a dust seal. The filter threads onto the rear cell of your telescope.
All other accessories, both visual and photographic (with the exception of Barlow
lenses), thread onto the skylight filter. The light loss caused by this filter is
minimal.
Solar Filter – (#94162) The AstroSolar® filter is a safe and durable filter that
covers the front opening of the telescope. View sunspots and other solar features
using this double-sided metal coated filter for uniform density and good color
balance across the entire field. The Sun offers constant changes and will keep
your observing interesting and fun.
T-Adapter (#93633-A) - T-Adapter (with additional T-Ring) allows you to attach
your SLR camera to the rear cell of your Celestron NexStar. This turns your NexStar into a high power telephoto
lens perfect for terrestrial photography and short exposure lunar and filtered solar photography
.
T-Ring - The T-Ring couples your 35mm SLR camera body to the T-Adapter, radial guider, or tele-extender.
This accessory is mandatory if you want to do photography through the telescope. Each camera make (i.e.,
Minolta, Nikon, Pentax, etc.) has its own unique mount and therefore, its own T-Ring. Celestron has 8 different
models for 35mm cameras.
Tele-Extender, Deluxe (#93643) - The tele-extender is a hollow tube that allows you to attach a camera to the
telescope when the eyepiece is installed. This accessory is used for eyepiece projection photography which
allows you to capture very high power views of the Sun, Moon, and planets on film. The tele-extender fits over
the eyepiece onto the visual back. This tele-extender works with eyepieces that have large housings, like the
Celestron Ultima series.
Vibration Suppression Pads (#93503) - These pads rest between the ground and tripod feet of your telescope.
They reduce the amplitude and vibration time of your telescope when shaken by the wind or an accidental bump.
This accessory is a must for long exposure prime focus photography.
Wedge, NexStar (#93658) – The wedge allows you to tilt the telescope so that its polar axis is parallel to the
earth's axis of rotation. Ideal for using your NexStar for guided astro photography.
