With this adapter you can add a filter drawer to your Williams Optics Redcat 51 and DSLR. You will have to use the correct M48 adapter for your camera type.

This is used by removing the original faceplate or tip-tilt adapter on the RedCat 51. You can then thread this adapter directly to the scope giving you the correct threads and backfocus to use a Starizona Filter Slider and your DSLR with 55mm of backfocus.

See the starizona website for more pictures of how to do this.
