Canon DSLR adaptor (1 Viewer)

Hi, I'm getting on very well digiscoping by just hand holding my Canon EOS 500D with 18-55mm lens up the eyepiece of my Opticron ES100 scope. However I would like to explore a more robust option. Does anyone know of a good adaptor which will allow me to keep the lens on my camera and shoot through the eyepiece - such as a support bracket or something similar. I see there are some for the Swarvoski scopes but are they likely to fit the opticron eyepiece?

Hope you can help.

Thanks

Simon

This maybe?

Gotta look yourself

Hi, thanks. Indeed, have looked through the web and there are options but wanted to know if anyone had any experience of any. I infact have the opticron push fit adaptor but don't get on well with it. Thanks
