Lhires III Spectrograph M42x0.75 Front Plate
If you wish to mount a T-threaded accessory in front of the Shelyak Lhires III Spectrograph, you can replace the standard front plate with this M42 x 0.75 front plate. Most users switch out the front plate so they can mount a T-threaded Barlow in front of the Lhires III.
