Sony RX100 M1 Attached to Telescope

Prolog... | Eyepiece and Adapters | Camera Attached to Eyepiece | Camera Attached to Skymax-102 Telescope | Camera Attached to Skymax-127 Telescope | References

On this page, I demonstrate how I attach the Sony RX100 M1 to a telescope eyepiece with a T mount filter thread for taking astro photos using the projection technique. Projection technique means that the camera is mounted to the eyepiece, not directly to the telescope. The latter technique can only be used with SLR cameras where the body can be directly attached to the telescope - typically using a T mount adapter.

BTW: I mention the 1:50 method on this site several times. This is a simple variant of the projection technique - you hold the camera by hand to the eyepiece instead of attaching it firmly...

 

Prolog...

At the beginning a few warnings:

 

Eyepiece and Adapters

Here, you can see the Revelation 32 mm DigiScope eyepiece and the two adapters needed to mount the Sony RX100 M1 with MagFilter filter adapter to the eyepiece. A second adapter, a step-down ring 52-37, is required, because there is no T mount adapter available, which directly fits the filter thread of the MagFilter adapter (52 mm). You can remove the upper part of the eyepiece including the eyecup to reveal the T mount filter thread.

Camera Attached to Eyepiece

Camera Attached to Skymax-102 Telescope

Here, you can see the Sony RX100 M1 attached to the Sky-Watcher Skymax-102 telescope (Maksutov-Cassegrain) and the Revelation 32 mm DigiScope eyepiece.

Attention: The small Dobson base (taken from the Heritage 100P) is extremely wobbly and shaky and therefore not a "recommendation," but only shown here for demonstration purposes. If I actually use this base, I hang the camera's shoulder strap around my neck to avoid the worst!

Ditto, with Amici prism

Warning: Using the Sony RX100 M1 at an Amici prism with the MagFilter filter adapter is dangerous, because the camera can easily fall down. The magnet is not strong enough to hold the camera securely in place, at least, mine is not (there are different reports on the Internet about the strength of the magnet...). The same applies to using the zenith prism if you point the scope higher up!
