Description

This is the standard shaft that is shipped with the Mach1GTO from Astro-Physics. It is the same diameter - 1.125" - and uses the same counterweights - 6 lb. (6SLCWT) and 9 lb. (9SLCWT) - as the shafts for their Astro-Physics 400 and 600E mounts. The end that attaches to the mount's declination axis was re-designed and incorporates a lead-in to start you out right and a shoulder to stop the shaft firmly against the counterweight shaft adapter without any binding.

Specifications

The usable length is 13.625" and it will hold over 60 lb. of counterweights. The shaft itself weighs in at 4.1 lb. (1.9 kg)

This shaft requires the Machined Safety Stop Knob (MSSKB).

This shaft is recommended for: all 400, 600, 800 and Mach1GTO mounts produced by Astro-Physics. This counterweight shaft can be used on mounts equipped with shaft encoders.

Customer Reviews (4.0 / 5 · 5 reviews)

Steven ★★★★★

I was relieved the 1.125" diameter fit my existing 9 lb counterweight perfectly, no wobble at all. The shaft arrived well-packed and the machining is smooth, which made balancing my setup much easier.

Riley ★★★★★

My old Astro-Physics shaft had some wear, but this one slides into the mount saddle just as smoothly as the original. The 1.125-inch diameter is machined precisely, and it holds my 6-pound weight securely during long imaging sessions.

Sebastian ★★★★☆

Took a while to arrive, but this shaft fits the existing counterweights perfectly and the 1.125" diameter is exactly as specified. Solid steel feel, no wobble once tightened down.
