Ok last night have new adapter and experimenting with lenses and exposures. Top photo is the belt of Orion and the horsehead nebula a 3.2 second exposure on my new Canon T3 with my B&L lense operating at 500mm at f/10 ISO 6400. The Bottom is same equipment at ISO 1600 1/30 second exposure. I am still waiting on my drive corrector and I have yet to use my DSLR adapter. Its kinda heavy but I am happy with it it appears to be built solid. So I have some experimenting to do.
