Description

This finely-machined STL Camera Adapter was designed for the 3.5" Focuser of the 305 mm f/3.8 Riccardi-Honders Astrograph. It connects securely to the face plate of SBIG STL cameras using the included four 6-32 x 1/2" Sockethead Cap Screws. It then is inserted into the Riccardi-Honders focuser and the focuser's three thumb screws tightened, anchoring securely into the circular dovetail of the adapter.

The new circular dovetail style was developed to not only provide a secure method of attaching the extra weight of modern CCD camera systems, but to also provide an easy way to rotate them to any position and then to flawlessly lock attachments with zero tilt.

Unlike the Astro-Physics Prime Focus Field Flatteners, there are no critical spacing requirements with this scope.

This adapter has a net spacing distance of 1.41" (35.92 mm).

Henry P. ★★★★★

Threaded onto my 305mm Riccardi-Honders without any wobble, the fit is absolutely precise. The machining is so clean that it mates perfectly with the STL’s face plate, and I had zero tilt in my test exposures.

Grace ★★★★★

Took my astrophotography setup to the next level—the machining is so precise that the camera plate aligns perfectly with the focuser threads without any wobble. Setup was straightforward and the fit feels rock solid.

Lucy ★★★★★

Perfectly matched my 305mm Riccardi-Honders focuser — the threads engage smoothly and the camera sits dead flat with zero tilt. It’s definitely a step up from the generic adapters I’ve tried before.
