1. บทนำ
This manual provides instructions for the proper setup, operation, and maintenance of your Bushnell Tasco LumiNova 40060578 Telescope. Designed for beginners and amateur astronomers, this refracting telescope offers a gateway to exploring the night sky.
Key features include a 76mm objective lens, a 6x24 finderscope for easy object location, and a diagonal mirror for comfortable viewing. The telescope also comes with a solar filter for safe solar observation (when used correctly) and a Tasco SkyWatch CD-ROM to assist with celestial navigation.

2. การติดตั้งและการประกอบ
Follow these steps to assemble your telescope. Ensure all components are handled with care.
- แกะส่วนประกอบ: นำชิ้นส่วนทั้งหมดออกจากบรรจุภัณฑ์อย่างระมัดระวัง และตรวจสอบกับรายการบรรจุภัณฑ์
- ประกอบขาตั้งกล้อง: Extend the tripod legs and secure them. Ensure the tripod is stable on a level surface.
- Attach Equatorial Mount: Secure the equatorial mount head to the top of the tripod. Tighten all locking screws.
- Mount Optical Tube: Attach the telescope's optical tube to the equatorial mount. Ensure it is balanced and securely fastened.
- ติดตั้ง Finderscope: Slide the 6x24 finderscope into its bracket on the main optical tube and tighten the retaining screws.
- Insert Diagonal Mirror: Insert the diagonal mirror into the focuser drawtube. Secure it with the thumbscrew.
- ใส่เลนส์ใกล้ตา: Choose an eyepiece (e.g., the lowest magnification for initial setup) and insert it into the diagonal mirror. Secure it with the thumbscrew.
3. การใช้งานกล้องโทรทรรศน์
3.1 การปรับแนวกล้องเล็ง
The finderscope helps you locate objects quickly. It must be aligned with the main telescope.
- Point the main telescope at a distant, stationary object (e.g., a tree top or street light) during daylight hours.
- จัดวางวัตถุให้อยู่ตรงกลางช่องมองภาพของกล้องโทรทรรศน์หลัก
- Look through the finderscope and adjust its alignment screws until the same object is centered in the finderscope's crosshairs.
3.2 การโฟกัส
Once an object is centered, turn the focuser knob slowly until the image appears sharp. Fine adjustments may be needed as objects move or conditions change.
3.3 การเปลี่ยนกำลังขยาย
To change magnification, simply swap eyepieces. Higher magnification eyepieces have smaller focal lengths (e.g., 10mm vs. 25mm). Always start with the lowest magnification (largest focal length eyepiece) to locate objects, then switch to higher magnifications for more detail.
3.4 Using the Solar Filter
WARNING: NEVER look directly at the sun through your telescope or finderscope without a professionally manufactured, certified solar filter properly installed over the front of the objective lens. Permanent eye damage or blindness will result.
The included solar filter is designed for safe solar observation. Ensure it is securely attached to the front of the telescope's objective lens before pointing the telescope at the sun. Do not use the finderscope during solar observation unless it also has a proper solar filter.
3.5 Using the Tasco SkyWatch CD-ROM
The Tasco SkyWatch CD-ROM provides a database of over 10,000 celestial objects. Install it on your computer to plan your observing sessions and identify stars, planets, and deep-sky objects visible from your location.
4. การบำรุงรักษาและการดูแล
- การทำความสะอาดเลนส์: Use a soft, lint-free cloth specifically designed for optical lenses. Breathe lightly on the lens surface to fog it, then gently wipe in a circular motion from the center outwards. Avoid touching optical surfaces with your fingers.
- พื้นที่จัดเก็บ: When not in use, store the telescope in a dry, dust-free environment. Keep all caps on the objective lens and eyepiece openings to prevent dust accumulation.
- การดูแลทั่วไป: Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Do not overtighten screws or force any components.
5 การแก้ไขปัญหา
| ปัญหา | สาเหตุที่เป็นไปได้ | สารละลาย |
|---|---|---|
| ภาพเบลอหรือไม่โฟกัส | การตั้งค่าโฟกัสไม่ถูกต้อง | Adjust the focuser knob slowly until the image is sharp. |
| Difficulty finding objects. | Finderscope is not aligned. | Align the finderscope with the main telescope as described in Section 3.1. |
| ภาพมืดหรือสลัว | Using too high magnification for conditions; light pollution. | Switch to a lower magnification eyepiece. Observe from a darker location if possible. |
| ไม่พบภาพใดๆ | Dust caps still on; eyepiece not inserted correctly. | Remove all dust caps. Ensure eyepiece is fully inserted and secured. |
