Grafton Public Library

Telescope Information & Usage Instructions

Thanks to the Aldrich Astronomical Society, and the generosity of Wyman-Gordon and Homefield Credit Union (formerly, Grafton Suburban Credit Union), the Grafton Public Library now has tabletop telescope for members to borrow.

Reserve the telescope through the C/W MARS catalog.

We are so pleased to be part of the Library Telescope Program!

This is an Orion Starblast 4.5″ reflecting telescope that works using two mirrors to reflect an image through the eyepiece.

To balance the telescope, tighten the large silver screw on top of the tube. Then, turn the black knob on the side. The telescope should move freely but slowly. Be careful not to over tighten either the screw or the knob.
NOTE: Do NOT completely unscrew the silver screw or the telescope will FALL OUT of the holder and serious damage will occur.

The focus adjustment is on the eyepiece. Turn the silver and black knobs back and forth until the image you want to see comes into focus.

The eyepiece has several strengths of magnification from 8mm to 24mm. The higher the power, the smaller the piece of sky you will be able to see.

The blue and gray foam ring is to place in the eyepiece for those unused to looking through a telescope. It will help your eye look straight down and make viewing easier.

Using the EZ-FINDER II (behind the eyepiece), turn the black knob on the side and look through the finder until you see a red laser dot. For ease of focusing on what you want to look at in the sky, aim the dot at what you wish to see first, and then look through the eyepiece. You can aim the dot by turning the knob on the side of the finder and looking through its scope until you see it.

Dark area – no street lights or house lights. If you are reading the sky charts or manual for the telescope outside in the dark, use the red headlamp setting, not the bright white setting.

If you wish to look at the moon, leave the large lens cap on and just pull the small gray plug out. This will block much of the moon’s brightness and help you see it more clearly.
