Complete with original box and an optional extension which you will probably need to reach focus. Uses compression ring which will not mark your eyepieces. Unit has a built in camera rotation adjuster. I was also able to use it very successfully for prime focus on my FS128 and Nikon D100. New cost is $179 for the TCA-4 and $25 for the extension tube. The first $100 gets it all. This includes shipping CONUS. Check or MO must clear bank before I ship. Paypal accepted with no additional fee.
Thank you for looking.
