Celestron ExploraScope 80AZ Refractor Telescope Instruction Manual

Introduction

The Celestron ExploraScope 80AZ is a refractor telescope designed for both celestial and terrestrial observations. Its manual alt-azimuth mount provides intuitive navigation of the night sky, making it suitable for beginners. This manual provides essential information for setting up, operating, and maintaining your telescope to ensure optimal performance and longevity.

What's in the Box

Upon unpacking, verify that all components are present:

• Telescope Tube
• Adjustable Height Tripod
• Accessory Tray
• Lens Cap
• 90° Erect Image Diagonal
• StarPointer Finderscope
• 20 mm Eyepiece

Setup

Follow these steps to assemble your Celestron ExploraScope 80AZ telescope:

1. Tripod Assembly: Extend the tripod legs to the desired height and secure them. Attach the accessory tray to the center brace of the tripod.
2. Mounting the Telescope Tube: Place the telescope tube onto the alt-azimuth mount, aligning the mounting screws with the holes on the tube. Secure the tube firmly.
3. Attaching the Finderscope: Slide the StarPointer finderscope into its bracket on the telescope tube and tighten the retaining screw.
4. Inserting the Diagonal: Insert the 90° erect image diagonal into the focuser. Tighten the thumbscrew on the focuser to hold it in place.
5. Inserting an Eyepiece: Insert the desired eyepiece (e.g., 20mm for lower magnification) into the diagonal. Tighten the thumbscrew on the diagonal to secure it.
6. Barlow Lens (Optional): For increased magnification, insert the 3x Barlow lens into the diagonal before inserting an eyepiece.

Visual Setup Guide

This video provides a visual guide to setting up and using a Celestron ExploraScope telescope, demonstrating key features and accessories for observing celestial objects.

Operating the Telescope

The ExploraScope 80AZ features a manual alt-azimuth mount with a panning handle and clutch for smooth and accurate pointing. This allows you to move the telescope up/down and left/right to track objects.

Using the StarPointer Finderscope

The StarPointer red dot finderscope helps you quickly locate objects in the sky. Look through the finderscope and align the red dot with your target. Once aligned, the object should be visible in your telescope's eyepiece.

Changing Magnification

Your telescope comes with two eyepieces (20mm and 4mm) and a 3x Barlow lens. The 20mm eyepiece provides lower magnification and a wider field of view, ideal for locating objects. The 4mm eyepiece offers higher magnification for detailed views. The 3x Barlow lens triples the magnification of any eyepiece it's used with.

Daytime Observations

Thanks to the 90° erect image diagonal, your ExploraScope 80AZ can also be used for daytime observations of birds, wildlife, and distant landscapes. The erect image diagonal ensures that images are correctly oriented (not inverted or reversed).

Maintenance

Proper care will extend the life and performance of your telescope:

• Cleaning Optics: Use a soft, lint-free cloth and specialized optical cleaning fluid. Avoid touching optical surfaces with bare hands.
• Storage: Store the telescope in a dry, dust-free environment. Keep lens caps on when not in use to protect the optics.
• Mechanical Parts: Periodically check all screws and knobs for tightness. Do not overtighten.

Troubleshooting

If you encounter issues, consider the following:

• Blurred Images: Ensure the focuser is properly adjusted. Check if the eyepiece is securely seated. Atmospheric conditions can also affect image clarity.
• Cannot Find Objects: Verify that the finderscope is aligned with the main telescope. Start with the lowest magnification eyepiece (20mm) to locate objects.
• Image is Upside Down/Reversed: For astronomical viewing, this is normal. For terrestrial viewing, ensure the erect image diagonal is correctly installed.
