NEEWER LS-T9 Red Laser Collimator 1.25" 🔭
Description:
This red laser collimator helps align the optical elements of reflector telescopes to sharpen views of planets and deep sky objects. It suits amateur astronomers who need a quick, portable method to check and adjust collimation before observing or imaging, and it works with telescopes that accept a 1.25 inch eyepiece or the included 2 inch adapter.
Key Points
The device produces a clear laser dot for accurate alignment rather than a blurred shape, which makes centring the reflection straightforward. A simple ON/OFF switch and a single brightness level keep operation uncomplicated during field use. The aluminium alloy body is lightweight and machined with CNC precision, so it sits securely in the focuser without adding unnecessary bulk.
A side window lets you inspect the 45 degree target to verify that the return is centred, and the tool includes a small L shaped hex key to adjust three rotation points for fine tuning. According to the manufacturer, the collimator maintains its precision across wide temperature ranges and can operate down to around -30°C, which can be useful if you observe from colder locations. 🔭
Usage Recommendations
Insert the collimator into the telescope’s focuser like a standard eyepiece, then switch it on and observe the position of the laser on the secondary and primary mirror markers. Rotate and adjust the collimator via the three hex holes using the supplied key until the laser reflection is centred. For best results, perform collimation in low ambient light, as the laser dot may be harder to see in bright daylight. Also consider that the single brightness level means it cannot be dimmed for very dark-adapted eyes.
The small weight and compact profile make it easy to carry in an accessory case and use during observing sessions. ❄️
