FAQ

Q:

Where are the 3 screws for adjusting the secondary mirror?

A:

At first glance, it may look like you are missing the 3 screws that adjust your secondary mirror, however we are using Allen headed threaded inserts (screws) and they are recessed in the thread holes on the outside of the secondary mirror (FIG 1). Use a 1/16” Allen head wrench (as shown in FIG 2) to make the adjustments.

Q:

What is this screw on the top of one of my accessory rings?

A:

Some PowerSeeker EQ models have two accessory rings that are needed to attach the optical tube to the EQ mount. On the top of one of the rings is a threaded stud with a thumbwheel. This is designed to allow the attachment of a camera with a ¼-20 threaded insert. The ¼-20 thread pitch is standard in the photographic world. This is very beneficial when used in conjunction with the optional AstroMaster/PowerSeeker Motor Drive (part #93514) for sky tracking. This ¼-20 mount is not used to attach your telescope to the EQ mount and is not needed for using your telescope in the traditional manner.
See illustrations below for clarification.

Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
