I have set up nearly 1/2 dozen different types of scopes with both Vixen and Losmandy style base plates. Every part I purchased from ADM exceeded my expectations. The dovetail adapters and radius block adapters are excellent and very well thought out. I frequently mount a V series dovetail on the top of the scope to mount cameras, weights, and guide scopes onto the scope. I haven’t used the MDS series, but suspect it would be a better choice for this. The company is very responsive for technical support. I work as an optical engineer and the quality of this equipment (particularly the dovetail adapters) equal or exceed professional grade optical bench equipment at much lower cost.
