Description

When purchasing the QuadTCC the proper length Backfocus Spacer is included for the scope specified. However, when ordering the QuadTCC for a TEC scope you will also need to order a Drawtube End Cap (S35RFAA) for the focuser. This only applies to the TEC focusers. This part is integral to the Astro-Physics 3.5" focusers and is not needed as a separate purchase. The S35RFAA screws onto the drawtube's 4.100" x 24 thread (same as Starlight Instrument's 3.5" focuser end cap thread).

Customer Reviews (4.8 / 5 · 5 reviews)

Emma ★★★★★

Installing this endcap was a breeze, and it solved the backfocus issue I was worried about with the QuadTCC. The threading feels precise and snug, which gives me confidence it won't loosen during a session.

Hazel ★★★★★

The threading on this endcap matched perfectly with my drawtube, and the included backfocus spacer was exactly the right length for my setup. It feels solidly machined and locks in place without any play, which is crucial for keeping the optics aligned.

Andrew ★★★★★

Snapped right onto the drawtube threads with no wobble, which is exactly what I wanted for keeping dust off the QuadTCC backfocus spacer between sessions. Fit is snug enough that I don't worry about it slipping off in the dark.
