Similar to the ASA .73 reducer / corrector, which sells for about $1050. An F/4 Newtonian becomes F/2.8. Requires 65mm of back focus, which with my Canon XSi required 11mm of spacer rings which I will include. You would have to provide the proper T-ring for your camera. Great results with only 10 minutes of exposure. Photos on request.
