Note: The AutoStar II handbox and the microfocuser do not require batteries; the telescope supplies their power.

4.Attach microfocuser: Remove the dust cap from the rear cell port (5, Fig. 1) of the telescope. Thread the microfocuser adapter (B, Fig. 6) onto the rear cell port thread. Slide the microfocuser (C, Fig. 6) over the microfocuser adapter and tight- en the three hex screws (K, Fig. 6) using the provided hex key.

5.Attach Diagonal (or accessories)

1.25" Diagonal Prism Users: If using the 1.25" diagonal prism (G, Fig. 6), slide the 1.25" adapter (D, Fig. 6) into the microfocuser. Line up the thumbscrew into the groove in the microfocuser (Fig. 7a and 7b). Tighten the microfocuser thumb- screws (I, Fig. 6) to a firm feel only. Slide the 1.25" diagonal prism into the adapter (D, Fig. 6). Tighten the accessory adapter thumbscrew (H, Fig. 6) to a firm feel only.

SC Optional Accessory Users: If using any of the optional accessories (such as the Off-Axis Guider, T-Adapter, etc.; see page 44) with the LX200R SC models, slide the supplied SC accessory adapter (L, Fig. 6) into the microfocuser. Line up the groove on the side of the adapter with either of the microfocuser thumbscrews (Fig. 8a and 8b) and tighten that thumbscrew to a firm feel only. Slide the optional acces- sory into the accessory adapter. Tighten the other microfocuser thumbscrew to a firm feel only.

2.0" Diagonal Mirror Users: If using the 2.0" diagonal mirror, slide the mirror directly into the microfocuser. The adapters (H and L, Fig. 6) are not required. Tighten the thumbscrews (I, Fig. 6) to a firm feel only.

Plug in the microfocuser: Plug the microfocuser into the Focus port (13C, Fig. 1).

Note: If you wish to mount a camera directly to the microfocuser, you need to attach an optional T-Adapter to the microfocuser. See OPTIONAL ACCES- SORIES, page 44.

Important Note: The microfocuser is carefully adjusted at the factory. If it become necessary to adjust the microfocuser, it must be performed by fac- tory trained technicians. If the microfocuser is improperly adjusted, perform- ance will degrade and damage will result. Damage due to improper adjust- ments not authorized by the factory will not be covered under warranty.

6.Insert eyepiece: Remove the Series 5000 26mm 5-element Plössl eyepiece (1, Fig. 1) from its container and place it in the diagonal prism (G, Fig. 6) or diago- nal mirror. Tighten the eyepiece holder thumbscrew (2, Fig. 1) to a firm feel only. Rotate the mirror lock knob (9, Fig. 1) towards the “Unlock” position, until it feels loose—the telescope is shipped with the mirror locked.

7.Remove dust cover: Remove the dust cover (18, Fig. 1) from the optical tube assembly (19, Fig. 1) by gently prying it off.

8.Attach the handbox holder: Remove the handbox holder from the plastic bag. If necessary, loosen the lock knob (A, Fig. 10a) and place the clamp (B, Fig. 10a) about one of the fork arm handles (15, Fig. 1). Tighten the lock knob to a firm feel. Slide the AutoStar II handbox into the holder (C, Fig. 10a). You may also snap the handbox into the holder: Slide one side of the handbox into the holder and then firmly press the other side of the handbox into the holder until it snaps in place. Adjust the tilt of of the holder by loosening the lock knob and then moving the holder clamp to the desired angle. Retighten the lock knob.

Choosing an Eyepiece

A telescope’s eyepiece magnifies the image formed by the telescope’s main optics. Each eyepiece has a focal length, expressed in millimeters, or “mm.” The smaller the focal length, the higher the magnification. For example: An eyepiece with a focal length of 9mm has a higher magnification than an eyepiece with a focal length

of 26mm.

Your telescope comes supplied with a Series 5000 26mm 5-element Plössl eyepiece which gives a wide, comfortable field of view with high image resolution.

Low power eyepieces offer a wide field of view, bright, high-contrast images, and eye relief during long observing sessions. To find an object with a telescope, always start

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
