TMB Flattener

This dedicated field flattener for FLT scopes provides an excellent flat field and nice round stars using DSLR's equiped with APS sensors. However, the CCD adapter is equiped with an SCT thread which isn't too common on cameras and is just a little too narrow for full frame sensors. The supplied spacer for DSLR's with T-Thread is fine for cameras with smaller APS sensors but again not ideal with full frame DSLR's either. Connection problems aside the triplet lens is a wonderful design.
