and ETX-125AT telescopes may be remotely controlled from the PC display. The

#505 Cable Connector Set, permitting connection of ETX, Autostar and PC, is includ-

Eyepieces: For higher and lower magnifications, Meade Super Plössl (SP) and

Super Wide Angle (SWA) eyepieces (Fig. 34), as well as the Series 4000 8mm to

24mm Zoom eyepiece, yield high-resolution imaging with all ETX telescope models.

A useful selection includes the SP 9.7mm, SP 12.4mm and SWA 18mm. Under good

seeing conditions, Meade Ultra Wide Angle 4.7mm and 6.7mm eyepieces present the

widest obtainable fields of view at high powers and are well suited for observing the

Moon and planets. Powers obtained with each eyepiece are shown in the following

table.

#126 2x Barlow Lens: An amplifying lens, the multi-coated #126 2x Barlow (Fig. 35)

doubles the power of all eyepieces with which it is used. Insert the #126 into the

telescope’s eyepiece holder first, followed by an eyepiece. Example: By itself, the

26mm eyepiece yields a power of 73X with the ETX-125AT; when used with the #126

2x Barlow Lens, this eyepiece yields 146X.

#825 8 x 25mm Right-Angle Viewfinder: Included as standard-equipment on

ETX-105AT and ETX-125AT models, the 8 x 25mm Right-Angle Viewfinder (Fig. 36)

permits a comfortable 90° viewing position with 90mm ETX models as well. The #825

fits into the same bracket as the 8x21mm viewfinder supplied with ETX-90AT

telescopes. The viewfinder’s wide-angle 7.5° actual field facilitates object location.

Precise focusing of the image is accomplished with a helicoid mechanism.
