Installing SC-4C to FW8S-Aluma

I recently got my new filter wheel, camera, and guider, but I'm not sure how to physically connect them together. The attached image shows all of the hardware I currently have. The SC-4C can't mount to the filter wheel because the filter wheel motor is sticking up above the cover plate. It looks like it needs a spacer.

Also, the shutter for the SC-4C is sliding closed. Is there a lock for it? I worry that if the telescope is at an angle the shutter will slide closed and it will lose tracking.

 

Thanks, I'll keep an eye out for a message from Doug!

 

We do have a set of long screws (7/8" threaded), but no spacer. If the spacer could be sent over, that would be great. Thanks! We'll try that first.

 

Yes, sorry. The screws are 1.25" long. We have those!

 

Any update on when the spacer can be sent over?

 

I got the spacer today, but I'm still unsure how to assemble everything together. There is still not enough clearance with the space to get over the motor - maybe if the spacer was twice as thick? Is there some other way to attach everything? I'm assuming the spacer goes on the filter wheel, then the SC-4C, then the plate with the threads for the 2" tube.

 

I think the 0.45" spacer (ACC 18) is the correct size?

 

If I do that, I cannot use the 2" threaded tube. I need that to be able to attach the camera to the telescope. There is no way for me to attach the tube to the face of the SC-4C.

The threaded adapter needs to go on the face of the SC-4C so that I can screw on the 2" tube, and then attach the unit to the telescope with that tube.

 

Thanks! I'll keep an eye out for it.

 

The part came and I was able to get in installed, though there were some complications. The spacer has a small indentation/plateau which I assumed was supposed to fit inside the filter wheel aperture? This may not be the case as it was the same diameter as the filter wheel aperture and couldn't fit. To save on backfocus, I decided to fit it in by lightly filing the outer diameter of the spacer. However, the screws provided were too short and could not reach the tapped holes. I needed to buy 1 5/8" screws to go through the noseplate, SC-4C, and spacer, and attach to the filter wheel.

Additionally, the original screws I was given with my first order were also the wrong size. The FW8-S needs 4-40 screws, but I was given 6-32 screws. I suspect the guider was provided expecting an AFW filter wheel.
