Re: [APML] Sloppy T-Ring

Eric,
My Nikon has a little play between the T-adapter and the body.  When I
started astrophotography about 5 years ago, I used a large rubber band to
hold the body against the adapter.  I few times I forgot to bring the rubber
bands, so the camera was free to wiggle.  Even though I shoot usually from 1
to 3 hour exposures,  I haven't seen any effect from the looseness in my
pictures.

I expect that there could be two effects to look for:
1, slight out of focus on one side of the picture, or
2, elongated stars if the camera shifts during the exposure.  Look for these
errors, if you don't see them you probably don't have a problem.
