Frequently Asked Questions - Strike 120 PLUS Levenhuk
How do I align the finderscope on the Levenhuk Strike 120 PLUS?
During daytime, point the main telescope at a distant object (e.g., a tree). Look through the 25mm eyepiece and center the object. Then adjust the finderscope screws until the crosshair is centered on the same object. This ensures the finder matches the main scope.
What is the correct way to collimate the mirrors?
Use a collimation cap or laser collimator. Insert it into the focuser and adjust the secondary mirror screws to center the reflection of the primary mirror. Then adjust the primary mirror screws to center the reflection of the secondary holder. Check with a star test for fine-tuning.
Can I use the telescope with a smartphone for astrophotography?
Yes, you can use a smartphone adapter (not included) to attach your phone to the eyepiece. For better results, use a T-ring and T-adapter for a DSLR camera with the prime focus method.
How do I power the motor drive?
The motor drive can be powered via the included AC adapter or by inserting 8 AA batteries (not included) into the battery holder. The batteries allow portable use without mains power.
What is the maximum magnification I can achieve?
The maximum useful magnification is about 240x, limited by the aperture (120mm). Higher magnifications will result in a dim, blurry image. Use eyepieces between 4mm and 25mm for best results.
How do I clean the primary mirror safely?
Remove the mirror from the tube (carefully). Rinse with distilled water, then gently wipe with a clean microfiber cloth dampened with a mixture of distilled water and a few drops of dish soap. Rinse thoroughly and dry with a soft cloth or compressed air. Avoid rubbing hard.
Why can't I see anything through the telescope?
First, check that the dust cap is removed. Then, start with the 25mm eyepiece (lowest power) for easier target acquisition. Ensure the finderscope is aligned and point the telescope at a bright object (e.g., the Moon) to verify proper focus.
Is the telescope suitable for observing the Sun?
Only with a certified solar filter that covers the front of the tube. Never use an eyepiece solar filter. Without a filter, never point the telescope at the Sun, as it can cause immediate and permanent eye damage.
What accessories are recommended for better observations?
Additional eyepieces (e.g., 6mm, 15mm), a Barlow lens (2x or 3x), a moon filter, a star diagonal (for comfort), and a red flashlight to preserve night vision. Also consider a star chart app.
How do I set up the equatorial mount for polar alignment?
On a clear night, locate Polaris (North Star) and adjust the mount's latitude and azimuth until Polaris appears in the polar scope. Then fine-tune by adjusting the mount so that the telescope tracks the stars accurately with the motor drive.
