This manual provides essential information for the proper setup, operation, and maintenance of your Explore Scientific ED102 Essential Series 102mm Triplet Refractor Telescope. Please read this manual thoroughly before using your telescope to ensure optimal performance and longevity.

The Explore Scientific ED102 is an air-spaced apochromatic triplet refractor telescope designed for both visual observation and astrophotography. It features a 102mm aperture and a versatile f/7 focal ratio, providing brilliant, high-contrast views with minimal chromatic aberration.

2. د خوندیتوب معلومات

• Never look directly at the Sun through your telescope or its finder scope without a professionally made solar filter. د سترګو دایمي او نه بدلیدونکي زیان، په شمول د ړوندوالي، پایله کیدی شي.
• Always supervise children when they are using the telescope.
• د نظري اجزاو سره په احتیاط سره چلند وکړئ ترڅو د سکریچونو یا زیان څخه مخنیوی وشي.
• ډاډ ترلاسه کړئ چې ټیلسکوپ په خوندي ډول په یو مستحکم ټریپډ یا ماونټ کې نصب شوی ترڅو د ناڅاپي سقوط مخه ونیسي.

4.1. Mounting the Telescope

The ED102 optical tube is designed to be mounted on a compatible equatorial or alt-azimuth mount (not included). The cradle ring provides a secure attachment point.

1. Ensure your chosen mount is stable and properly set up according to its own instructions.
2. cl خلاص کړئamps on the cradle ring to allow the telescope tube to rotate.
3. Carefully place the telescope tube into the cradle ring, ensuring it is balanced.
4. Tighten the cradle ring clamps to secure the telescope.

This image shows the main telescope tube, which is white with black accents, securely held by two black cradle rings. The focuser end is visible on the right, and the dew shield is on the left. The cradle rings are attached to a dovetail plate (not fully visible) for mounting onto a telescope mount.

4.2. Attaching the Diagonal and Eyepiece

The diagonal redirects the light path, allowing for a more comfortable viewing position. The 2-inch diagonal is typically used with 2-inch eyepieces, but the included adapter allows for 1.25-inch eyepieces.

1. Remove the dust cap from the focuser.
2. Insert the 2-inch diagonal into the focuser drawtube. Secure it by tightening the thumbscrews on the focuser.
3. If using a 1.25-inch eyepiece, insert the 2-inch to 1.25-inch adapter into the diagonal, then insert your 1.25-inch eyepiece into the adapter. Secure with thumbscrews.
4. If using a 2-inch eyepiece, insert it directly into the diagonal. Secure with thumbscrews.

This image displays a black 2-inch diagonal, which is an angled accessory used to hold eyepieces, and two black extension tubes. These components are crucial for achieving proper focus and comfortable viewing with various eyepieces.

4.3. Attaching a Finder Scope (Optional)

A finder scope (not included) helps locate objects in the night sky. It typically mounts onto a shoe on the focuser assembly.

1. Slide the finder scope base into the dovetail shoe on the focuser.
2. Tighten the thumbscrew on the shoe to secure the finder scope.
3. Align the finder scope with the main telescope during daylight hours by pointing the main telescope at a distant, stationary object and then adjusting the finder scope's alignment screws until the object is centered in both the finder and the main eyepiece.

4.4. Connecting to a Mount and Accessories

The following video demonstrates the assembly of a telescope onto a tripod and the installation of various accessories, including a diagonal and a zoom eyepiece. While the specific telescope model in the video may vary, the general principles of attachment and setup are applicable.

5.1. تمرکز کول

Your ED102 telescope is equipped with a dual-speed focuser for precise adjustments.

1. Use the larger knob for coarse focusing to quickly bring objects into approximate focus.
2. Use the smaller knob for fine focusing to achieve a sharp, clear image. This is especially important for high-magnification viewing and astrophotography.

۳. د آسماني شیانو مشاهده

To begin observing, point your telescope towards a celestial object. Use the finder scope (if installed and aligned) to center the object, then look through the main eyepiece. Adjust the focuser until the image is sharp.

The ED102's apochromatic design provides excellent color correction, making it suitable for viewing planets, the Moon, and bright deep-sky objects like nebulae and star clusters.

5.3. Astrophotography with the ED102

The ED102 is well-suited for astrophotography due to its 102mm aperture, f/7 focal ratio, and air-spaced triplet optical design that minimizes chromatic aberration. You will need additional equipment such as a camera, camera adapter, and a sturdy equatorial mount with tracking capabilities.

6. ساتنه

۱. د آپټیکس پاکول

Dust and debris on the objective lens can degrade image quality. Clean only when necessary and with extreme care.

• Use a soft camel hair brush or a can of compressed air (held upright) to gently remove loose dust.
• For stubborn smudges or fingerprints, use a specialized optical cleaning solution and lens tissue. Apply a small amount of solution to the tissue, not directly to the lens, and wipe gently from the center outwards in a circular motion.
• د خپلو ګوتو سره د نظري سطحو لمس کولو څخه ډډه وکړئ.

۲. عمومي پاملرنه او ذخیره کول

• Always replace dust caps when the telescope is not in use.
• Store the telescope in a cool, dry place, away from direct sunlight and extreme temperature fluctuations.
• The retractable dew shield helps prevent dew formation on the objective lens during observing sessions. Extend it fully during use.
