Please note:

You will find inside the box an additional black T-thread adapter ring. Please retain it for future modifications. This T-thread adapter might be needed for imaging. The manufacturer Lunt-USA is looking to possible making some adapters to make imaging with the LS50THa telescope easier. Right now it will not reach focus on DSLR cameras. It will reach focus with some CCDs and webcams when you remove the eyepiece-holder from the blocking-filter diagonal. You will find there also a T-thread at the blocking-filter diagonal.
