설치 지침
Follow these steps to assemble your DÖRR Delta 1000 telescope.
1. Assemble the Tripod
- Extend the tripod legs to a stable position.
- Attach the accessory tray to the tripod spreader bars. Ensure it is securely fastened to provide stability.

2. Mount the Equatorial Mount
- Place the EQ-1 equatorial mount onto the tripod head.
- Secure the mount using the provided locking screw from underneath the tripod head.
- Attach the counterweight shaft and the counterweight to the mount. The counterweight helps balance the telescope.

3. Attach the Telescope Optical Tube
- Carefully place the telescope optical tube into the mounting rings on the equatorial mount.
- Secure the tube by tightening the screws on the mounting rings. Ensure the tube is firm but do not overtighten.

망원경 작동
1. 파인더스코프 정렬
파인더스코프는 넓은 시야를 제공합니다. view to help locate objects before observing them with the main telescope.
- During daylight, point the main telescope at a distant, stationary object (e.g., a treetop or building).
- Look through the main telescope with a low-power eyepiece (e.g., H20mm) and center the object.
- Now, look through the finderscope. Adjust the finderscope's alignment screws until the same object is centered in its crosshairs.
- This alignment ensures that whatever is in the center of your finderscope is also in the field of view of your main telescope.
2. 초점 맞추기
Once an object is centered, turn the focuser knobs slowly until the image appears sharp.
3. Using Eyepieces and Magnification
The magnification of your telescope is determined by the focal length of the telescope divided by the focal length of the eyepiece. The DÖRR Delta 1000 has a focal length of 1000mm.
- H20mm 접안렌즈: 1000mm / 20mm = 50x magnification. Ideal for wide-field views와 객체 위치 파악.
- H12.5mm 접안렌즈: 1000mm / 12.5mm = 80x magnification. Good for general planetary and lunar observation.
- SR6mm Eyepiece: 1000mm / 6mm = 167x magnification. For more detailed views of planets and the Moon.
- SR4mm Eyepiece: 1000mm / 4mm = 250x magnification. For high-power observation of specific features.
메모: The recommended maximum useful magnification for the DÖRR Delta 1000 is approximately 228x. While higher magnifications are technically possible, atmospheric conditions often limit the clarity of images beyond this point.

4. Using the 2x Barlow Lens
The 2x Barlow lens doubles the magnification of any eyepiece it is used with.
- Insert the Barlow lens into the focuser first.
- Then, insert your chosen eyepiece into the Barlow lens.
- Example Magnifications with Barlow Lens:
- SR4mm + Barlow: 250x * 2 = 500x
- SR6mm + Barlow: 167x * 2 = 334x
- H12.5mm + Barlow: 80x * 2 = 160x
- H20mm + Barlow: 50x * 2 = 100x
Remember the note about maximum useful magnification. High magnifications with the Barlow lens may result in less sharp images due to atmospheric conditions.
5. Using the Equatorial Mount (EQ-1)
The EQ-1 mount allows you to track celestial objects as they move across the night sky due to Earth's rotation.
- 극지 정렬 : For accurate tracking, the mount's polar axis should be aligned with the celestial pole (near Polaris in the Northern Hemisphere). This is a more advanced step and detailed instructions can be found in dedicated astronomy guides.
- Slow Motion Controls: Use the slow-motion control cables to make fine adjustments to the telescope's position in Right Ascension (RA) and Declination (DEC) axes. This allows for smooth tracking of objects.

유지
- 광학 장비 청소: Dust on the mirror or lenses can reduce image quality. Use a soft brush or compressed air to remove loose dust. For stubborn smudges, use a specialized optical cleaning solution and a microfiber cloth designed for optics. Avoid touching optical surfaces with bare hands.
- 저장: When not in use, store the telescope in a dry, dust-free environment. Cover the telescope with dust caps to protect the optics.
- 기계 부품: Periodically check all screws and bolts for tightness. Do not overtighten.
문제 해결
- 이미지가 흐릿함:
- 초점 조절 손잡이를 천천히 조정하여 이미지가 선명해질 때까지 조정합니다.
- Ensure the eyepiece is fully inserted and secured.
- Check for condensation or dirt on the eyepiece or main mirror.
- Atmospheric turbulence can cause blurring, especially at high magnifications.
- 객체를 찾을 수 없습니다:
- Ensure the finderscope is properly aligned with the main telescope.
- Start with the lowest magnification eyepiece (H20mm) for a wider field of view.
- Practice locating bright objects like the Moon or bright stars first.
- 이미지가 흐릿합니다:
- Ensure the dust caps are removed from both the main telescope and the finderscope.
- High magnification eyepieces will naturally produce dimmer images.
