Improved Finder Scope Bracket Addendum to the Instructions

#9024, 9025, 9086

During recent production of our Skywatcher 90 EQ (#9024), Explorer 90 AZ (#9025), and ShortTube 80 (#9086) tele- scopes, we developed an improved design for the finder scope bracket. The new design makes aiming the finder scope much easier, since it requires adjustment to only two alignment screws instead of three. As a result of this improve- ment, there are some discrepancies with the provided instruction manuals. These discrepancies will be clarified in this addendum.

#9024 Skywatcher 90 EQ

In the assembly section of the manual on page 4, line item

12 should now read:

12.To place the finder scope in the finder scope bracket, first unthread the two adjustment screws until the screw ends are flush with the inside diameter of the bracket. Place the O-ring that comes on the base of the bracket over the body of the finder scope until it seats into the slot on the middle of the finder scope. Slide the eyepiece end (nar- row end) of the finder scope into the end of the bracket’s cylinder that does not have the adjustment screws while pulling the spring-loaded tensioner on the bracket with your fingers. Push the finder scope through the bracket until the O-ring seats just inside the front opening of the bracket’s cylinder. Now, release the tensioner and tighten the adjustment screws a couple of turns each to secure the finder scope in place.

Page 5 explains how to align the finder scope. The instruc- tions are still valid, but to aim the finder scope, only adjustments to the two alignment screws are needed. The new finder scope bracket design also eliminates the need for knurled lock nuts on the alignment screws.

Refer to Figure 1 to identify the parts of the new finder scope bracket.

#9086 ShortTube 80

The second paragraph in the section of the instructions enti- tled “Getting Started” should now read:

The optics have been installed and collimated at the factory, so you should not have to make any adjustments to them. To place the finder scope in the finder scope bracket, first unthread the two adjustment screws until the screw ends are flush with the inside diameter of the bracket. Place the O-ring that comes on the base of the bracket over the body of the finder scope until it seats into the slot on the middle of the finder scope. Slide the eyepiece end (narrow end) of the find- er scope into the end of the bracket’s cylinder that does not have the adjustment screws while pulling the spring-loaded tensioner on the bracket with your fingers. Push the finder scope through the bracket until the O-ring seats just inside the front opening of the bracket’s cylinder. Now, release the tensioner and tighten the adjustment screws a couple of turns each to secure the finder scope in place. Secure the bracket to the “dovetail” mount on the optical tube with the knurled set screw provided. Insert the 45° diagonal into the focuser tube and secure with the knurled set screw. Slide an eyepiece into the diagonal and gently tighten the set screw.

The section in the manual entitled “Aligning the Finder Scope” is still valid, but to aim the finder scope, only adjust- ments to the two alignment screws are needed.

Refer to Figure 1 to identify the parts of the finder scope bracket.
