Understanding Your Telescope’s Components

Once assembled, familiarizing yourself with the key parts of the Celestron Astromaster 114 is essential. Knowing what each component does will greatly improve your ability to use it effectively.

The Optical Tube

This is where the magic happens. The optical tube of the Astromaster 114 is a Newtonian reflector. It uses a primary mirror at the bottom of the tube to collect light and a secondary mirror to direct that light to the side, where it enters the focuser.

The Equatorial Mount

The equatorial mount is designed to track celestial objects as they move across the sky. It has two axes: the right ascension (RA) axis and the declination (DEC) axis. For beginners, it’s important to understand that these axes allow you to follow an object simply by adjusting one knob, rather than two as with a simpler alt-azimuth mount.

The Focuser

The focuser is the part you’ll interact with most when trying to get a clear image. It’s a mechanism that moves the eyepiece in and out, allowing you to achieve sharp focus on your target. You’ll find focus knobs on the side of the focuser drawtube that you’ll turn slowly.

Eyepieces and Magnification

Eyepieces are small, interchangeable lenses that determine the magnification of your telescope. The Celestron Astromaster 114 typically comes with two eyepieces, usually a 20mm for wider fields of view and lower magnification, and a 10mm for higher magnification when viewing planets or the Moon.

Magnification is calculated by dividing the telescope’s focal length by the eyepiece’s focal length. For example, if your telescope has a focal length of 1000mm:

• With a 20mm eyepiece, magnification is 1000mm / 20mm = 50x.
• With a 10mm eyepiece, magnification is 1000mm / 10mm = 100x.

It’s generally recommended to start with lower magnification (the 20mm eyepiece) to locate objects and that you can experience up to 200x magnification with optional eyepieces for more detail on specific targets. For the Astromaster 114, it’s best to stay within 100x-150x for optimal clarity, especially in the light-polluted skies of Dubai. Higher magnification can make the image dimmer and more susceptible to atmospheric disturbances.

The Finderscope

The finderscope is a small, low-power telescope or a red-dot aiming device that helps you point your main telescope at your desired celestial object. Because the main telescope has a narrow field of view, it’s difficult to find things without a finder. A correctly aligned finderscope is crucial for successful stargazing.

Aligning the Finderscope: Your Gateway to the Stars

This is arguably the most critical step before you can start observing. An unaligned finderscope will lead to frustration, as you won’t be able to find anything with your main telescope, even if it’s pointed directly at it. This process is best done during the day.

Daytime Alignment Steps

Find a distant, stationary object. This could be a treetop, building, or a distant sign. It should be at least 100 meters (about 300 feet) away.

1. Point the Main Telescope: Use your main telescope with its lowest power eyepiece (the 20mm) to center the distant object in the field of view.
2. Look Through the Finderscope: Now, look through your finderscope. The object you centered in the main telescope should be visible in the finderscope’s view.
3. Adjust the Finderscope: Use the adjustment screws on the finderscope’s mount to move the crosshairs (if it’s a red-dot finder, you’ll adjust the red dot’s position) until they are precisely centered on the same object you centered in the main telescope.
4. Verify: Once aligned, point your main telescope at a different distant object and repeat the process to ensure the finderscope is accurately tracking with the main telescope.

Once your finderscope is aligned, it should remain aligned unless it’s bumped or dropped. This daytime alignment makes nighttime observing much more efficient.

Observing with Your Celestron Astromaster 114

Now that your telescope is assembled and your finderscope is aligned, you’re ready to start stargazing. Here’s how to begin your observations.

Choosing a Location

While Dubai is known for its incredible cityscape, light pollution can be a challenge for stargazing. For the best views, try to find a location away from bright lights. Parks on the outskirts of the city, desert areas, or even rooftops with minimal ambient light can offer significantly better contrast. If you’re observing from a balcony, try to shield your telescope from nearby lights.

Setting Up for Observation

1. Stable Ground: Place your tripod on a firm, level surface.
2. Balance the Mount: Adjust the counterweights so that the telescope tube can be moved smoothly in all directions without drifting. This is essential for tracking celestial objects.
3. Allow for Cool-Down: If you’ve brought your telescope from a warm indoor environment outside, let it sit for at least 30 minutes to adjust to the ambient temperature. This helps reduce internal air currents that can degrade image quality.

Finding and Focusing on Objects

1. Start with Bright Objects: Begin with easy targets like the Moon, bright planets (Jupiter, Saturn, Venus), or bright guide stars. These are easier to locate.
2. Use Your Finderscope: Aim your telescope at the general area where your object is located. Use the finderscope to precisely center the object in its crosshairs.
3. Switch to the Main Eyepiece: Once the object is centered in the finderscope, look through your lowest power eyepiece (20mm) in the main telescope. The object should be visible, though possibly not centered or in focus.
4. Center the Object: If the object is in view but not centered, gently move the telescope using the mount’s slow-motion controls.
5. Focus for Sharpness: Slowly turn the focus knobs on the focuser. You’ll notice the image go from blurry to sharp. Keep turning until the image is as clear as possible. For planets, you’ll be looking for crisp disks and any visible moons or rings.
6. Increase Magnification (Optional): Once you have a good focus with the low-power eyepiece, you can try switching to your higher-power eyepiece (10mm) for a closer look. Remember to refocus after changing eyepieces.

Pro Tip:

Get acquainted with the night sky. Using a stargazing app on your phone (like SkyView or Star Walk) can help you identify constellations and find celestial objects even before you point your telescope.

Common Celestial Objects to Observe

The Celestron Astromaster 114 is capable of showing you a variety of fascinating celestial objects. Here are some popular targets for beginners:

The Moon

Our closest celestial neighbor is an excellent first target. You can see craters, mountains, and rilles in incredible detail. Try observing the terminator (the line between day and night on the Moon) where the shadows are long, enhancing the relief of surface features.

Planets

• Jupiter: You can often see its four largest moons (the Galilean moons) as tiny points of light orbiting the planet. With good conditions, you might even glimpse cloud bands.
• Saturn: The rings of Saturn are a breathtaking sight, even in smaller telescopes like the Astromaster 114. You’ll also be able to see its largest moon, Titan.
• Mars: When Mars is closer to Earth, you can observe some surface features and its polar ice caps.
• Venus: Venus shows phases, similar to our Moon, due to its position relative to the Sun and Earth.

Deep-Sky Objects (DSOS)

While brighter nebulae and galaxies might be tough in urban environments, you can still find rewarding views of some DSO’s in darker skies:

• The Orion Nebula (M42): Visible in winter months, this is a spectacular star-forming region.
• The Andromeda Galaxy (M31): The closest large galaxy to our own Milky Way. It appears as a faint smudge of light but is an awe-inspiring sight.
• Star Clusters: Open clusters like the Pleiades (M45) and globular clusters like M13 are beautiful to observe.

Maintenance and Care for Your Telescope

Proper care ensures your Celestron Astromaster 114 remains in excellent condition for years of stargazing enjoyment. Regular maintenance is simple and effective.

Cleaning the Optics

The most important part of telescope maintenance is keeping the optics clean. However, it’s crucial to do this correctly to avoid damaging the mirrors.

• Dust: Use a soft brush (like a camel hair brush) or a can of compressed air to gently remove loose dust from the primary and secondary mirrors. Never wipe a dry, dusty mirror, as this can cause scratches.
• Smudges: For fingerprints or stubborn smudges, use a specialized lens cleaning solution and lint-free optical wipes. Apply a small amount of cleaner to the wipe, not directly to the mirror. Clean in a circular motion, starting from the center and working outwards.
• Never use household cleaners or abrasive materials on your telescope optics.

Storage

Store your telescope in a cool, dry place away from extreme temperature fluctuations and direct sunlight. Keeping the optical tube covered with its dust cap when not in use is essential.

Collimation

Collimation refers to aligning the mirrors within the optical tube. For the Astromaster 114, which is a Newtonian reflector, periodic collimation can improve image quality, especially if the telescope has been moved or bumped. There are many guides and videos available online on how to collimate a Newtonian telescope using collimation caps or laser collimators.

A well-maintained telescope will always provide better views and a more rewarding stargazing experience.
