In order to use the Takahashi TCE0100 collimating scope with Takahashi reflectors and non-Takahashi reflectors, such as the Astro-Tech and GSO Ritchey-Chrétiens, you will need this TCN0055 adapter. The collimating scope threads into the TCN0055 and the resulting collimating scope/adapter combination slips into the 2" focuser of the telescope.
