I broke a T-ring...

Yes so... how easy are these things to break?
Bought a T-ring the other day to use with my Canon. First use tonight the damn thing breaks on me!

Unless I am missing something?

The inside ring (that is free to rotate) has come out, and the nobbly bits that are meant to keep it from doing so seem to not be extended far enough.

This really shouldn't happen should it?
It was 3.5 degrees out there... so maybe it deformed from the change in temp.

Luckily for me I'd hooked the strap of the camera over the finderscope or it would have been bye bye camera...

Oh well reduced me to piggybacking for the night but with the moon so bright yuck. Still makes for an interesting effect, single frame 1.5 min then stretched to inkyness in PS.

Bugger!, self reminder to myself now to ensure the camera is fastened in someway so it doesnt hit the floor.
What brand t-ring was it ?

Nice pic, has an artistic feel to it.

Have a look for 3 tiny srews which are supposed to grip down on the bit that fell out. Put it back in and tighten them up

It didn't break, it just wasn't tightened up properly Jazza. They're not designed to rotate although they do when loose. The internal flanged ring is held in with three small set screws spaced at 120 degrees around the rim - just tighten them with a jewellers screwdriver. The idea here is that the nosepiece is interchangable between 2" and 1.25", and fits whatever bayonet you require to suit your camera - so they're all swappable.

If you want camera angle rotation you'll need to have a focuser with that function built-in, such as the zero-shift William Optics offerings.

Right thanks guys!
Having a closer look it looks like they're those hexagonal screw thingies.
Oh well, no harm no foul!
