You can buy the new holder too though and it will fit the older LHIRES. It adds to the total cost but the mirror slit itself is already the major cost item. Is it worth upgrading? If your metal slit is in good condition, possibly not unless you change your slit width often or need the dual width photometric slit. It is actually less reflective than the metal slit and does not suffer from the ghost images that the mirror slit produces.
