DANGER Read this manual carefully before attempting to assemble the MAX-ACF mount and attaching the OTA. Follow steps as outlined in this manual in order to assemble the telescope safely. Failure to follow steps may result in injury or death, and/or damage to the telescope and mount.
CONTENTS WARNING! ® Never use a Meade MAXACF™ Telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult supervision while observing.
TELESCOPE FEATURES Note: Your telescope and mount may look slightly different from the one shown in some of the images in this manual. However, your telescope will still operate as the one described in this manual. Components of MAX MAX features a unique modular design that allows a couple of individuals to assemble, either permanently or transportably, a mount twice the size of any other commercially available mount.
RA Lock Knob Pedestal Assembly MAX's Pedestal assembly can be configured to cover three latitude ranges without the need of disassembly. Together, the three ranges allow the mount to operate anywhere on the planet.
Right Ascension Housing Assembly The RA Housing mates to the Pedestal easily, sliding firmly into a dovetail block that measures over 100 square inches. When locked in place, this broad footprint assures that your mount will operate as a single rigid block delivering accurate and repeatable pointing and tracking performance. The RA Housing contains Meade's patented Autostar II telescope control system, a massive 13.625" pitch diameter worm gear attached to a 3.
Declination Housing Assembly DEC ASSEMBLY The Dec Housing mates to the RA Housing using another huge dovetail block. The RA Housing, DEC Housing and Pedestal are all designed to allow you to track more than 6 degrees past meridian without interference. This mount will let you cover the whole sky.
pedestal attachment lever course adjustment lock lever fine adjustment turnbuckle THE TRIPOD MAX Tripod The MAX-ACF tripod can be transported or permanently installed. It provides a wide stance to assure that it can safely carry MAX's massive payload in all orientations, but still collapses down to a size that is easy to handle. Its design assures that despite its wide stance, it will not interfere with optical systems observing on the meridian.
Optical Tube Assembly MAX-ACF is delivered with a 20” Advanced Coma-Free™ Optical Tube Assemblie. Its 20” OTA integrates seamlessly with MAX-ACF German Equatorial Mount.

Follow this procedure: • Important Note: Press MODE at any time to exit Focus modes. Press the Number Key 4 and Autostar displays "OTA: Fast" displays. You are now in control of the MAX-ACF focuser. • Use the Up/Down keys to scroll through the MAX-ACF focuser speeds.
Aligning for the First Time Important Note: First time you align the telescope, perform the following procedures to insure precision pointing: 1. Automatic Align 2. Drift Align 3. Collimation 4. OTA Align (if non -MAX-ACF model) 5. Calibrate home. If you wish to have precise pointing accuracy, the first time you align your telescope you will need to align it to using Automatic Alignment and Drift Alignment. You will then electronically collimate the telescope, square the OTA and finally calibrate home.
How to Drift Align Max (Northern Hemisphere) Important Note: You will need a reticle to perform this procedure Note: See: http://www.astrocruise.com /polarnew.htm for a website dedicated to drift alignment of Meade telescopes. Site offers extensive tips from an experienced drift align specialist. 1. Center your reticle on a bright star near the Eastern horizon. 2. Look through the reticle while pressing Autostar's right and left Arrow keys. This will slew the mount back and forth in the R.A. axis. 3.
Follow these steps for collimation of the optical system: The only adjustments possible, or necessary, on the MAX-ACF models is performed with the AutoStar handbox. No adjustment screws are necessary (or provided), as with traditional telescopes. A high-powered eyepiece, such as a 9mm eyepiece, or a 9mm eyepiece with a 2x barlow, is required for collimation.

Object Menu Almost all observing with Autostar II is performed using the Object menu category. (Note: Exceptions include Guided Tour and Landmark Survey.) Autostar II contains many libraries of viewable objects, such as stars, planets, comets, nebulae and so forth. When one of these objects is selected from a library, Autostar II moves your telescope (if properly aligned) and points it at the selected object. Six of the most popular libraries can be accessed directly using the hot buttons.
Browse: Allows you to search the library for objects with certain parameters, much like a search engine. "Edit Parameters" lets you set various parameters for the search, such as: Object Type, Minimum Elevation, Largest, etc. Once you have set the parameters of the search, select "Start Search" and press ENTER. Autostar II will display the results of the search. Event Menu The Event menu provides access to dates and times of astronomical events.
OTA Fan: Allows you to turn the fan off or on if you have an MAX-ACF model. The fan assists with the stabilization of the optics. The fan should be activated at the beginning of an observing session and run until the optics have achieved an equilibrium with the environment. Fan operation time should range from about 5 to 25 minutes. Note that the fan may introduce a slight vibration and this may cause noticeable movement observed with sensitive optics.

APPENDIX A: LATITUDE CHART Latitude Chart for Major Cities of the World To aid in the polar alignment procedure, latitudes of major cities around the world are listed below. To determine the latitude of an observing site not listed on the chart, locate the city closest to your site. Then follow the procedure below: Northern hemisphere observers (N): If the site is over 70 miles (110 km) North of the listed city, add one degree for every 70 miles.
APPENDIX B: THE MOON The Moon option of the Object menu allows you to observe the moon in a way never possible before. You will be able locate many specific features of the lunar surface, including hundreds of craters, mare, valleys, and mountains. One special feature allows you to view all six Apollo landing sites.
APPENDIX C: Smart Mount Introduction Smart Mount improves the pointing accuracy of your MAX-ACF telescope's "Go to" system. Despite careful efforts to calibrate and align telescopes, they may fail to precisely center objects. Smart Mount allows your telescope to learn about, and then correct for, any systematic pointing errors, regardless of the cause.
• Save your model, using a good, descriptive name, using the “Save As” menu. Upon completion of the training, Smart Mount is enabled and remains on until you choose “Off” from the Smart Mount Configuration menu. Permanently Mounted Scopes For permanently mounted telescopes, it is not necessary to have more than one model unless the weight and balance of auxiliary equipment introduces balance or flexure changes that significantly affect pointing.
APPENDIX D: How to Read the Latitude Scale Introduction As Max needs to be polar aligned, you will need to set the latitude scale for you latitude range. The Latitude scale has three sets of measurements, one for each latitude range: 0 to 30°, 30° to 60° and 60 to 90°. Note that there are five extra degrees beyond both 0 and 90°. This allows you to add for latitudes just slightly below 0 and just slightly above 90 degrees.
