1. መግቢያ

This manual provides instructions for the proper assembly, operation, and maintenance of your Visionking 90700SCF Refractor Astronomical Telescope. This instrument is designed for both celestial observation, such as viewing the moon and planets, and terrestrial observation, allowing for detailed viewing of distant land objects. Please read this manual thoroughly before using your telescope to ensure optimal performance and longevity.

2. የደህንነት መረጃ

• Never look directly at the sun through the telescope or its finder scope without a professionally manufactured solar filter. ዓይነ ስውርነትን ጨምሮ ዘላቂ እና የማይቀለበስ የአይን ጉዳት ሊያስከትል ይችላል።

4. ስብሰባ እና ማዋቀር

ቴሌስኮፕዎን ለመሰብሰብ የሚከተሉትን ደረጃዎች ይከተሉ

4.1. ትራይፖዱን ያዘጋጁ

1. ትሪፖዱን ከማሸጊያው በጥንቃቄ ያስወግዱት።
2. የሶስትዮሽ እግሮች ሙሉ በሙሉ እስኪዘረጉ እና እስኪረጋጉ ድረስ ወደ ውጭ ያሰራጩ።
3. የሶስትዮሽ እግሮችን ቁመት በሚፈልጉት መንገድ ያስተካክሉ viewing level, ensuring the tripod head remains level. Secure the leg clamps.
4. Attach the accessory tray (if included) to the center brace of the tripod.

4.2. Mount the Telescope Optical Tube

1. Locate the mounting bracket on the telescope tube and the corresponding attachment point on the tripod head.
2. Carefully place the telescope tube onto the tripod head, aligning the mounting holes.
3. Secure the telescope tube to the tripod using the provided screws or clamps. Ensure it is firmly attached but do not overtighten.

4.3. Attach the Finder Scope

1. Slide the finder scope into its bracket on the main telescope tube.
2. Tighten the small thumbscrews on the bracket to secure the finder scope. Do not overtighten.

4.4. Insert an Eyepiece

1. በፎከሰር መጎተቻ ቱቦ ላይ ያለውን የአውራ ጣት ዊንጣ ይፍቱ።
2. Insert either the K25mm or K9mm eyepiece into the focuser. The K25mm eyepiece provides lower magnification and a wider field of view, ideal for initial object location.
3. Tighten the thumbscrew to secure the eyepiece.
4. To use the 3x Barlow lens, insert it into the focuser first, then insert an eyepiece into the Barlow lens. This will triple the magnification of the eyepiece.

5. የአሠራር መመሪያዎች

5.1. Aligning the Finder Scope

The finder scope must be aligned with the main telescope for easy object location.

1. በቀን ብርሃን ወቅት ዋናውን ቴሌስኮፕ ሩቅ፣ የማይንቀሳቀስ ነገር (ለምሳሌ፣ ሩቅ ዛፍ ወይም ሕንፃ) ላይ ያመልክቱ።
2. Look through the main telescope with the K25mm eyepiece and center the object in the field of view.
3. Now, look through the finder scope. Use the adjustment screws on the finder scope bracket to move the crosshairs until they are centered on the same object.
4. Once aligned, the finder scope will help you quickly locate objects in the night sky.

5.2. ትኩረት መስጠት

To achieve a clear image, adjust the focuser:

1. Point the telescope at an object.
2. Turn the focus knob slowly until the image appears sharp.
3. Fine-tune the focus for the clearest possible view.

5.3. ማጉላትን መቀየር

Different eyepieces provide different magnifications. To calculate magnification, divide the telescope's focal length (700mm) by the eyepiece's focal length.

• K25mm Eyepiece: 700mm / 25mm = 28x magnification. With 3x Barlow: 28x * 3 = 84x.
• K9mm Eyepiece: 700mm / 9mm = 78x magnification. With 3x Barlow: 78x * 3 = 234x.

Start with the lowest magnification (K25mm) to locate and center objects, then switch to higher magnifications (K9mm, or with Barlow) for more detailed views.

6. ጥገና

• የጽዳት ሌንሶች; Use a soft, lint-free cloth or a specialized optical cleaning brush to gently remove dust. For smudges, use a small amount of optical cleaning fluid on a clean cloth. Avoid touching optical surfaces with your fingers.
• ማከማቻ፡ Store the telescope in a dry, dust-free environment. Keep dust caps on the objective lens and focuser when not in use.
• አጠቃላይ እንክብካቤ Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Do not disassemble the optical components.

7. መላ መፈለግ

• ምስሉ ደብዛዛ ነው፡- Adjust the focus knob slowly. Ensure the eyepiece is fully inserted and secured. Allow the telescope to acclimate to the ambient temperature.
• ነገሮችን ማግኘት አልተቻለም፦ Ensure the finder scope is properly aligned with the main telescope. Start with the lowest magnification eyepiece (K25mm) for a wider field of view.
• ምስሉ ደብዛዛ ነው፡ This is normal for very high magnifications or when observing faint objects. Ensure your viewing location is dark and free from light pollution.
• ምስሉ ተገልብጦ/ተገልብጦ ነው፡ This is normal for astronomical telescopes. For terrestrial viewing, an optional erecting prism (not included) can correct the image orientation.
