How To Use Orion Telescope

by

Learning how to use an Orion telescope can feel a bit overwhelming at first. But with a little guidance, you’ll be seeing the rings of Saturn or the craters of the Moon in no time. This guide will walk you through every step, from unboxing your new telescope to finding your first deep-sky object. We’ll cover the basics of setup, alignment, and observation, making sure you get the most out of your instrument.

How To Use Orion Telescope

Using your telescope successfully starts with understanding its parts and how they work together. Every Orion model, from a simple reflector to a computerized GoTo scope, shares common principles. Let’s break it down into simple, manageable steps.

Unboxing and Initial Assembly

When your telescope arrives, take your time. Carefully remove all components from the box and lay them out on a soft surface, like a carpet. Check the manual’s packing list to ensure every part is present.

  • The Optical Tube: This is the main body of the telescope. Handle it by the tube, not the focuser or finderscope.
  • The Mount: This is the tripod and head that holds the tube. It’s crucial for stability.
  • Accessories: Eyepieces, finderscope, diagonal (for refractors), and any tools will be in separate boxes.

Assemble the mount and tripod first, making sure all knobs are tight. Then, attach the optical tube to the mount using the provided rings or bracket. Don’t attach any accessories yet.

Understanding Your Telescope’s Key Parts

Before you go outside, familiarize yourself with the main components. Knowing what each part does is half the battle.

The Mount: Altazimuth vs. Equatorial

Orion sells two main types of mounts. The Altazimuth moves up-down (altitude) and left-right (azimuth). It’s simple, like a camera tripod. The Equatorial mount is tilted to align with Earth’s axis; it’s designed to follow stars smoothly but has a steeper learning curve.

Eyepieces and Magnification

Eyepieces determine your magnification. The number on the eyepiece (e.g., 25mm, 10mm) is its focal length. A higher number gives a wider, brighter view with lower magnification. Start with your longest focal length eyepiece (like 25mm) to find objects easily.

To calculate magnification, divide the telescope’s focal length (found in the manual, e.g., 1300mm) by the eyepiece focal length. A 1300mm scope with a 25mm eyepiece gives 52x power.

The Finderscope: Your Guiding Star

This is the small telescope or red-dot sight on the side of the main tube. Its wide field of view helps you point the big telescope precisely. Aligning it is your most important step before observing.

First Night Setup: A Step-by-Step Guide

Now for the practical part. Follow these steps for your first successful observing session.

  1. Set Up Indoors (Daytime): Practice moving the telescope and using the focuser. Attach your finderscope and a low-power eyepiece.
  2. Align Your Finderscope in Daylight: Point the main tube at a distant, stationary object (like a telephone pole). Center it in your eyepiece. Then, without moving the tube, adjust the screws on the finderscope until the same object is centered in its crosshairs or red dot. This makes night alignment much easier.
  3. Move Outside at Dusk: Let your telescope acclimate to the outside temperature for at least 30 minutes. This reduces internal air currents that blur images.
  4. Choose a Stable Location: Set up on solid ground, not a wooden deck. Avoid looking over rooftops or asphalt that radiates heat.
  5. Start with the Moon: The Moon is an easy, spectacular first target. Use your aligned finderscope to point at it. Look through the eyepiece and turn the focus knob slowly until the image becomes sharp.

Aligning and Using an Equatorial Mount

If your Orion telescope has an equatorial mount, don’t be intimidated. The extra setup is worth it for smooth tracking.

  1. Set the Latitude: Adjust the mount’s tilt to match your latitude (e.g., about 40° for New York). A scale is usually on the mount’s side.
  2. Point the Axis North: Rotate the entire tripod so the mount’s main axis (the one with the counterweight) points roughly at Polaris, the North Star.
  3. Balance the Tube: Loosen the clutch and slide the tube forward/back in its rings until it stays put when you let go. Do the same with the counterweight shaft. A balanced scope is easier to move and strains motors less.
  4. Use the Slow-Motion Controls: Once on a target, you can use the fine adjustment knobs to follow it as the Earth rotates.

Operating Computerized “GoTo” Orion Telescopes

Orion’s StarSeek or IntelliScope systems can find objects for you, but they require a proper start-up routine.

  1. Power Up: Insert fresh batteries or use an AC adapter. Weak power causes tracking issues.
  2. Enter Time/Location: Accurately input your date, time, time zone, and location (latitude/longitude). Use a GPS or phone app for precise coordinates.
  3. Perform Star Alignment: The hand controller will ask you to center 2 or 3 bright stars in the eyepiece. Use your highest-power eyepiece for precise centering. Take your time here—good alignment means good GoTo accuracy.
  4. Select and Slew: Once aligned, choose an object from the database. The telescope will slew to it. It may not be perfectly centered; use the hand controller to nudge it into view.

Finding Objects in the Night Sky

Star-hopping is a rewarding skill. You use star charts or apps to “hop” from bright stars you know to fainter targets.

  • Start with Bright Planets and Stars: Venus, Jupiter, and Sirius are unmistakably bright.
  • Use a Star Chart or App: Apps like Stellarium or SkySafari show you what’s up in your sky tonight.
  • Move Slowly: The sky moves faster than you think. Use gentle taps on the telescope.
  • Let Your Eyes Adapt: Spend at least 20 minutes in the dark. You’ll see much more detail.

Focusing and Getting the Best View

A blurry image is usually just out of focus, not a problem with the telescope.

  1. Always start by racking the focuser all the way in (toward the telescope).
  2. Slowly turn the knob to extend the focuser outward while looking through the eyepiece.
  3. Stop as soon as the object snaps into sharp view. For stars, focus until they are tiny, sharp pinpoints of light.
  4. If you wear glasses for astigmatism, keep them on. If you’re just nearsighted, you can usually remove them and use the focuser to compensate.

Maintenance and Care Tips

Your telescope is a precision instrument. A little care goes a long way.

  • Lens Cleaning: Only clean optics when absolutely necessary. Use a rocket blower first to remove dust. For smudges, use lens tissue and a drop of optical cleaner made for coatings.
  • Storage: Keep the telescope in a dry, room-temperature place. Use dust caps on both ends of the tube and on eyepieces.
  • Avoid Condensation: If you bring a cold scope inside, put lens caps on to prevent dew from forming on the optics. Let it dry out before storing.
  • Collimation (for Reflectors): Newtonian reflectors need occasional alignment of their mirrors. Orion provides a simple collimation cap or tool. Check it every few sessions.

Common Troubleshooting Issues

Every stargazer faces these problems. Here’s how to fix them.

  • Can’t See Anything Through Eyepiece: Ensure all lens caps are off. Check if the finderscope is wildly misaligned. Try focusing very slowly across the full range.
  • Image is Shaky: Tighten all tripod and mount knobs. Don’t extend tripod legs fully if you don’t need too. Hang a weight bag from the tripod’s center hook for stability.
  • Stars Look Like Little Doughnuts: Your reflector’s mirrors need collimation. This is a normal adjustment procedure.
  • GoTo Misses Targets: Re-do your alignment with more care. Ensure your time/location data is correct. Make sure the telescope is level.

Recommended First Targets for Your Orion Telescope

Start with these easy and impressive objects to build your confidence.

  1. The Moon: Always stunning. Look along the “terminator” (line between light and shadow) for the best crater detail.
  2. Jupiter: You can see its four largest moons and the cloud bands on its surface.
  3. Saturn: The rings are visible even at moderate power. It’s a sight you’ll never forget.
  4. The Pleiades (M45): A beautiful star cluster that fits perfectly in a low-power view.
  5. The Orion Nebula (M42): A bright, fuzzy patch in Orion’s sword. It’s a stellar nursery.

Upgrading Your Experience

As you get more comfortable, a few accessories can greatly improve your sessions.

  • Better Eyepieces: Upgrading to wider-field eyepieces (like Orion’s “Expanse” line) gives more comfortable views.
  • Moon & Planetary Filters: These screw into eyepieces to reduce glare and enhance contrast on the Moon and planets.
  • A Red Flashlight: Preserves your night vision. Cover a regular flashlight with red cellophane.
  • A Star Atlas or Book: “The Night Sky Observer’s Guide” or “Turn Left at Orion” are fantastic resources.

FAQ Section

How do I set up my Orion telescope for the first time?
Start by assembling the mount and tripod in daylight. Then attach the optical tube. The most critical step is aligning your finderscope on a distant daytime object. This makes finding night targets possible.

Why can’t I see anything through my telescope?
First, check that all lens caps are removed. Second, ensure you are using a low-power eyepiece (like a 25mm). Third, your finderscope might be badly misaligned—point the main tube at a bright star and re-align the finder. Finally, turn the focus knob through its full range slowly.

What is the best way to clean my Orion telescope’s lenses?
Avoid cleaning unless necessary. Use a bulb blower to remove loose dust. For fingerprints, use a drop of lens cleaner designed for optics and very gently wipe with a microfiber cloth or lens tissue in a circular motion. Never press hard or use household cleaners.

How do I use the equatorial mount on my Orion scope?
Set the mount’s latitude scale to your location. Point the main axis (the one with the counterweight) at the North Star. Balance the telescope tube and counterweight. Once on a target, you can track it by turning only the right ascension slow-motion knob.

My Orion GoTo telescope isn’t finding objects correctly. What’s wrong?
Most often, the initial alignment wasn’t precise enough. Re-do the star alignment, making sure to center each alignment star perfectly in a high-power eyepiece. Also, double-check that your time, date, and location (including daylight savings time) are entered correctly in the hand controller.

Remember, patience is your best tool. Your first few sessions might be frustrating, but it gets easier quickly. The key is to practice the steps during the day so your not fumbling in the dark. Astronomy is a journey, and every clear night is a new chance to learn something amazing about the universe with your Orion telescope.
