The threaded attachment that connects the Atik 383L to the filter wheel is causing me trouble. I figured the filter wheel's threads were worn out. The camera adaptor for the filter wheel is being sent to me by Andrew after I sent him an email. Recently, I gave the DMK camera adaptor a go, and it appeared to attach well via the thread. I'm now perplexed. Has anyone else had issues with filter wheels and camera thread wear?
