How To Use A Orion Telescope

by

So you’ve got your hands on an Orion telescope. That’s exciting! Figuring out how to use a Orion telescope might seem a bit daunting at first, but don’t worry. This guide will walk you through everything, from unboxing to finding your first galaxy. With a little patience, you’ll be navigating the night sky in no time.

How to Use a Orion Telescope

This main section covers the universal steps that apply to most Orion telescope models. Whether you have a simple tabletop reflector or a computerized GoTo scope, these fundamentals are your starting point.

Step 1: Unboxing and Initial Assembly

Open the box carefully and lay out all the parts. You should have the optical tube (the main body), the mount, the tripod legs, and an accessory box. The accessory box typically holds eyepieces, a finderscope, and maybe a diagonal.

  • Assemble the Tripod: Extend the tripod legs to a comfortable height and lock them. Avoid making it too tall; stability is more important.
  • Attach the Mount: Secure the mount head to the top of the tripod. This is usually done with a central bolt or a locking plate.
  • Mount the Optical Tube: Place the tube into the mount’s rings or onto the dovetail plate. Tighten the screws firmly, but don’t over-tighten and strip the threads.

Step 2: Attaching Essential Accessories

Your telescope needs a few key parts to work. First, if you have a reflector telescope, you’ll need to insert the eyepiece directly into the focuser. For a refractor or catadioptric telescope, you need a diagonal first.

  1. For refractors/SCTs: Slide the star diagonal into the focuser and tighten the set screw.
  2. Choose your lowest power eyepiece (the one with the highest mm number, like 25mm or 32mm). Insert it into the diagonal or focuser.
  3. Remove the dust caps from both ends of the optical tube and from the eyepiece.

Step 3: Aligning the Finderscope

This is the most critical step for success. A misaligned finderscope makes finding anything impossible. Do this during the day, aiming at a distant object like a telephone pole or chimney.

  1. Point your main telescope at the distant object. Center it precisely in the eyepiece.
  2. Look through the finderscope. You’ll likely see the object, but not centered.
  3. Adjust the finderscope’s adjustment knobs or screws until the object is perfectly centered in the finderscope’s crosshairs.
  4. Double-check by looking in the main eyepiece again. If it’s still centered, your finderscope is aligned. This makes nighttime aiming much easier.

Step 4: Balancing and Setting Up the Mount

A balanced telescope moves smoothly and dosen’t strain the mount’s motors (if it has them).

  • Alt-Azimuth Mounts: Simply ensure the tube is seated securely. Loosen the locks and move it around to get a feel for the motion.
  • Equatorial Mounts: This requires more setup. You must polar align it. Point the mount’s polar axis (the one that tilts) roughly toward Polaris, the North Star. This allows you to track objects by turning just one knob.
  • Computerized Mounts: Follow the manual’s initialization procedure. It will often ask you to input date, time, and location, then perform a star alignment.

Understanding Eyepieces and Magnification

The eyepiece determines your magnification. You calculate it by dividing the telescope’s focal length (printed on the tube) by the eyepiece’s focal length. A 1000mm scope with a 25mm eyepiece gives 40x power. Start with low power (like 40x) to find objects. It gives a wider, brighter view. Switch to higher power (like 200x) for closer looks at the Moon or planets once the object is centered.

Step 5: Finding Your First Night Sky Objects

Start with easy, bright targets. The Moon is the perfect first target. It’s bright, detailed, and easy to find.

  1. Let your telescope sit outside for 30 minutes to acclimate to the temperature. This prevents wobbly views from warm air escaping the tube.
  2. Using your unaided eye, locate the Moon.
  3. Look through your aligned finderscope and move the telescope until the Moon is in the crosshairs.
  4. Look through the main eyepiece. The Moon should be there! Use the focus knob slowly until the craters snap into sharp view.
  5. After the Moon, try bright planets like Jupiter or Saturn. Then move on to star clusters, like the Pleiades.

Specific Instructions for Different Orion Telescope Types

Orion makes several types of telescopes. Here’s some model-specific advice to help you get the best from your particular design.

Using an Orion Refractor Telescope

Refractors use lenses. They are often low-maintenance and great for lunar, planetary, and wide-field viewing. Ensure you always use a diagonal with these for comfortable viewing. The image might be upside-down or mirrored, which is normal for astronomical scopes. Watch out for dew forming on the front lens; a dew shield can help prevent this.

Using an Orion Reflector Telescope (Newtonian)

These use mirrors. They offer great aperture for the price. A key task for reflectors is occasional collimation—aligning the mirrors. You’ll need a simple collimation cap or laser collimator. If stars look like little comets instead of sharp points, your scope needs collimation. Also, the primary mirror is at the bottom of an open tube, so be careful not to bump it or let dust settle on it.

How to Collimate a Newtonian Reflector

  1. Insert a collimation cap into the focuser.
  2. Look through the cap’s small hole. You’ll see the primary mirror with a center spot, the secondary mirror, and the reflection of your own eye.
  3. Adjust the secondary mirror tilt screws until the primary mirror’s center spot is centered under the focuser.
  4. Then, adjust the primary mirror’s tilt screws (at the back of the tube) until your eye’s reflection is centered in the primary mirror’s center spot.

Using an Orion GoTo Computerized Telescope

These scopes, like the SkyQuest XT series, can find objects for you. The setup is crucial for accuracy.

  • Power it Properly: Use a reliable power source, like a portable power tank. Avoid weak batteries.
  • Initialization: Enter the exact time, date, and your coordinates accurately.
  • Alignment: The scope will ask you to center 2 or 3 bright stars in the eyepiece. Use a high-power eyepiece for precise centering. The better you align it, the better it will find faint objects later.
  • Remember, even with GoTo, you still need to know how to manually point it and understand the sky a little.

Essential Tips for Better Viewing

These practices will dramatically improve your experience and what you can see.

Let Your Eyes Adjust to Darkness

It takes about 20-30 minutes for your eyes to fully adapt to low light. Avoid looking at white lights during this time. Use a red flashlight to protect your night vision if you need to read a star chart or adjust equipment.

Observe from a Dark Location

Light pollution is the biggest enemy. If you can, drive away from city lights. Even going to a local park can make a huge difference. You’ll see many more stars and fainter objects.

Be Patient and Keep a Log

Astronomy rewards patience. Some nights the air will be turbulent, making views blurry. Other nights will be crystal clear. Keep an observing logbook. Note the date, object, eyepiece used, and what you saw. Over time, you’ll train your eye to see more detail.

Maintenance and Care

  • Always replace dust caps when storing.
  • Store the telescope in a dry, temperature-stable place.
  • Clean optics only when absolutely necessary, and use proper lens cleaning fluid and microfiber cloths. Never wipe a dry lens.
  • Avoid touching any glass surface with your fingers.

Troubleshooting Common Problems

Things don’t always go smoothly. Here’s how to fix frequent issues.

  • I see nothing but black: You are likely pointed at empty sky. Use the finderscope to aim at a bright star or the Moon first. Also, check that all dust caps are removed and you are using an eyepiece.
  • The image is blurry: Adjust the focus knob slowly through its full range. If it’s still blurry, your scope might need collimation (reflectors) or the air might be very turbulent (“bad seeing”).
  • Stars look like little seagulls: This is a sure sign your reflector needs collimation. Follow the collimation steps outlined earlier.
  • The telescope shakes too much: Make sure the tripod legs are fully locked and not over-extended. Hang a small weight from the center of the tripod to stabilize it. Avoid touching the scope while viewing.
  • GoTo scope isn’t accurate: Redo the alignment process. Ensure your time, date, and location are 100% correct. Center alignment stars as precisely as possible.

Recommended First Targets for Your Orion Telescope

Here’s a list of fantastic objects to look for, in order of difficulty.

  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 cloud bands and its four largest moons (the Galilean moons).
  3. Saturn: The rings are visible even at moderate power. A breathtaking sight.
  4. The Pleiades (M45): A beautiful star cluster that looks great in a low-power eyepiece.
  5. The Orion Nebula (M42): A bright nebula visible in the winter constellation Orion. You can see its fuzzy, cloud-like structure.
  6. The Andromeda Galaxy (M31): The most distant object you can see with your naked eye. It will appear as a faint, fuzzy oval.

FAQ Section

How do I set up my Orion telescope for the first time?

Start by assembling the tripod and mount. Then attach the optical tube. Insert your lowest-power eyepiece and align the finderscope on a distant daytime object. This daytime setup makes your first night much smoother.

Why can’t I see anything through my telescope?

The most common reasons are: 1) All dust caps aren’t removed, 2) The finderscope isn’t aligned, so you’re pointed at empty sky, or 3) You’re using too high a magnification to start. Always begin with your lowest power eyepiece (highest mm number) to find objects.

What is the best Orion telescope for a beginner?

Orion’s SkyQuest XT6 or XT8 Dobsonian reflectors are often recommended. They offer simple point-and-view operation with a lot of aperture for the price, making them great for seeing faint deep-sky objects. The StarBlast series is also excellent for a more compact option.

How do I maintain my Orion telescope?

Keep it covered and in a dry place. Avoid cleaning the optics unless absolutely necessary. If you must clean, use compressed air first, then special lens cleaner and microfiber cloth. For reflectors, learn to collimate the mirrors periodically.

Can I use my Orion telescope to look at land objects?

Yes, but many astronomical telescopes show an inverted or mirrored image, which can be disorienting for terrestrial viewing. Some models offer an erecting prism you can buy separately to correct the image for land use.

What accessories should I buy first?

A better eyepiece or two is a great start. A 2x Barlow lens doubles the power of your existing eyepieces. A moon filter reduces the Moon’s glare for more comfortable viewing. A planisphere (star chart wheel) is invaluable for learning the night sky.

Learning how to use a Orion telescope is a journey. Don’t expect to master everything in one night. Start with the basics: assembly, finderscope alignment, and focusing. Your first clear view of Saturn’s rings or Jupiter’s moons will make it all worthwhile. Remember, every astronomer was once a beginner looking at the Moon for the first time. So take your scope outside, be patient with yourself, and enjoy the incredible views of our universe.
