Series 4000 Nebular Filters: A modern boon to the city-dwelling deep-space

 

 

observer, the interference nebular filter effectively cancels out the effects of most

 

 

urban light pollution, while leaving the light of deep-space nebular emissions virtual-

 

 

ly unattenuated. Meade Series 4000 Nebular Filters utilize the very latest in coating

 

 

technology, and are available with threaded cells for eyepieces or for attachment to

 

 

the rear cells of Meade Schmidt-Cassegrain models.

 

 

Variable Tele-Extender:For eyepiece-projection photography of the Moon and the

 

 

planets, a Tele-Extender is required. The Variable Tele-Extenderthreads onto the

telescope's eyepiece-holder, into which is inserted an eyepiece of typically about

 

26mm focal length; the 35mm camera body couples to the tele-extender by means of

Eyepiece.

 

 

a T-Mount. The Meade Variable Tele-Extenderpermits a range of projection images.

 

 

 

 

#928 45° Erect-Image Diagonal Prism: Diagonal mirrors and prisms result in images

 

 

 

that are correctly oriented up-and-down but reversed left-for-right. For terrestrial

 

 

observing a fully correctly oriented telescopic image is desirable; the #928 Diagonal

 

 

Prism accomplishes this image correction and places the eyepiece at a convenient

 

 

45° viewing angle. The #928 is for use with the 1.25" Eyepiece-Holder.

 

 

Series 4000 Plössl 9mm Illuminated Reticle Eyepiece: The most advanced com-

 

 

mercially-available illuminated reticle eyepiece, the Series 4000 Plössl 9mm model,

 

 

powered by an internal battery, includes micrometric x-y positioning controls which

 

 

greatly facilitate locking onto the guide star: Turn the finely-threaded controls and

 

 

place the reticle’s crossline pattern precisely at the desired position in the field. The

complemented by a rubber eyecup (foldable for eyeglass wearers) that shuts out dis-

 

 

tracting stray light from the observer’s eye. The upper (lens) section of the eyepiece

 

 

rotates on a fine thread for precise diopter adjustment to the user’s eye. Reticle pat-

 

 

tern is a double crossline with two concentric circles.

 

 

#62 T-Adapter:The T-Adapter is the basic means of prime-focus photography through

 

 

all Meade Schmidt-Cassegrain models. Thread the T-Adapter on to the rear cell of

 

 

your telescope, followed by a T-Mount for your 35mm camera, and the camera body

 

 

is rigidly coupled to the telescope.

 

 

#777 Off-Axis Guider: The Off-Axis Guider provides a means during long-exposure

 

 

astrophotography for the photographer to monitor the tracking of the telescope to

 

 

assure that the telescope remains precisely positioned on the object being pho-

tographed. Like the T-Adapter, the Off-Axis Guider couples the camera body to the

 

telescope but it also causes a small amount of the guidestar’s incoming light to be

 

 

 

 

diverted at a right angle, where the star’s position can be examined for tracking errors

 

 

with an illuminated reticle eyepiece; position corrections can then be effected using

 

 

 

 

Autostar II.

 

 

Piggyback Brackets (not available for 20" model): Piggyback photography is one

 

 

 

of the most popular and easiest ways to get started in astrophotography. Attach your

 

 

 

35mm camera, with its own 35mm-to-250mm lens, atop your MAX-ACF in equatorial

 

 

 

mode, and guiding the camera through the main telescope, wide-field photos of the

 

 

 

Milky Way of remarkable detail and clarity can be taken.

 

 

 

Dew Shields (not available for 20" model): In moist climates, water particles sus-

 

 

 

pended in the atmosphere may condense on the front surface of the telescope's cor-

 

 

 

recting plate. This dew formation may be inhibited to a significant extent by the addi-

 

 

 

tion of a dew shield, essentially an extension tube attaching to the front-cell of the tel-

 

 

 

escope.

#905 Variable Polarizer (1.25"): #1A Skylight Filter: The #905 system includes 2

 

 

 

Polarizer filters mounted in a specially-machined cell, for glare-reduction in observ-

 

 

 

ing the Moon. Rotate the thumbscrew at the side of the unit to achieve light trans-

 

 

 

mission between 5% and 25% of its original value. The #905 inserts into the diago-

 

 

 

nal mirror of the telescope, followed by an eyepiece. The #1A Skylight Filter threads

 

 

 

onto the rear cells of all Meade MAX-ACF models and effectively seals the interior of

 

 

 

the telescope from dust. All other rear cell accessories may then be threaded to the

 

 

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the

Sun. Do not look through the telescope as it is moving.
