How to Use Reflector Telescopes
Reflector telescopes use a system of internal mirrors to focus incoming light such that the object emitting the light is magnified. To accomplish this, the mirrors inside a reflector telescope are parabolic, with the concave side facing the incoming light source. Light rays that hit the mirror are focused into a single point due to the mirror's curvature. From there, the light is reflected into an eyepiece, through which you observe the telescope image.

Find a safe, dark location to set up your reflector telescope. Ideally, this location is as far from the city as possible, as city lights and pollution obscure the image of the night sky. If possible, choose an elevated position with a wide-open view of the sky.
-
2
Set up your telescope tripod on a solid surface. For best results, choose a dirt or concrete location. Setting your telescope up on a deck or other wood surface will transmit a greater amount of vibration into the tripod legs, thus obscuring the telescope image.

Use a star chart and compass to locate objects in the night sky. In addition to stars, star charts feature constellations, planets and other astronomical features. Orient your telescope directionally with the compass, ensure the star chart is set to the proper time and date, then compare the star chart to your perspective of the night sky from the angle of the telescope. Objects in the sky will line up with illustrations on the chart.

4
Use the finder scope to browse the night sky and locate distant objects. The finder scope features a significantly smaller magnification than the main reflector telescope, allowing you to peruse different areas of the sky more easily than by using the main scope.
-
5
Direct the main telescope lens at the object you locate with the finder scope. This requires fine-tuning the position of the telescope body. If your reflector telescope features interchangeable eyepieces, try out different ones to view the object at various magnifications.
-
6
Keep unused eyepieces stored in their proper containers, as otherwise dew and debris are likely to accumulate on the lens. Likewise, install the main lens cap whenever you are not looking through the telescope to prevent condensation from obscuring your view. If your lenses or eyepieces accumulate dew or other debris, use a soft microfiber cloth to wipe them clean. Be careful not to smudge the lens or grind the debris into the glass.
