How to Mount a Finderscope on a CCA-250

Quick Answer

Mount a finderscope on a CCA-250 by attaching the dedicated 7X50 finderscope bracket to the camera angle adjuster's accessory port, then securing the finderscope in the bracket's rings.

Step-by-Step Mounting Instructions

1. Step 1: Attach the Bracket to the CCA-250: Locate the accessory port on the CCA-250. Place the finderscope bracket over the port so the screw holes align. Insert the two supplied screws and tighten them evenly with a Phillips screwdriver. Do not overtighten—snug is sufficient to avoid stripping the threads. Check that the bracket sits flush against the CCA-250 body. A gap indicates misalignment; loosen and reposition before tightening fully.
2. Step 2: Secure the Finderscope in the Bracket: Slide the finderscope tube into the bracket's rings until the eyepiece is at a comfortable viewing position. Tighten the ring screws by hand just enough to hold the finderscope in place. Do not fully tighten yet—you will need to adjust alignment. Ensure the finderscope is oriented so the eyepiece points toward the rear of the telescope for easy access.
3. Step 3: Align the Finderscope with the Main Telescope: Point the main telescope at a distant daytime target (e.g., a utility pole or treetop). Center the target in the main eyepiece. Look through the finderscope and adjust the ring screws to center the crosshairs on the same target. Tighten the ring screws firmly once aligned. Recheck alignment after tightening—screws can shift the finderscope slightly. Repeat the adjustment if needed.
