I am building a Dob and would like to upgrade my 50mm RACI from a 8x50 GSO to a 9x50 Stellarvue. However, I don't want to do this right now, but in a year or so. I'd rather spend my money upgrading EPs at this point. I am wondering, would I be able to use the same mounting shoe used on the 8x50 GSO or would I need to buy a specific one for the Stellarvue 50-60mm rings. I am concerned about drilling new mounting holes in order to switch mounting shoes down the road.

I think this is the ring set you want:

That should fit the standard Synta mounting shoe.  The SV50 is a great finder.  I tried the 60mm version a while back, but wasn't happy with it.  The field curvature of the 60mm version was too much for me, but the SV50 is great.  Nice bright sharp image.  I use mine with an 11mm ES eyepiece making it about an 18x finder with a 4.5* FOV.  A perfect compliment to my red dot finder.

Thanks Jon and Jason! 

 

My decision now is whether or not to buy the Stellarvue 50-60mm rings that have a lower profile and mount my 8x50 GSO RACI in the rings until I upgrade to Stellarvue 50mm RACI or just buy the Stellarvue 50-60mm rings that fit the Synta shoe. I do like the lower profile. Less weight and bulk to deal with.

I use the low profile rings on my scope. They both use the same style shoe. Just a matter of having the clearance everywhere to use the low profile design.

How high is the finders lens cell from the surface of your dob?

Even lower profile:  https://agenaastro.c...base-dfb50.html

 

Double-check that the ring diameter will suffice for the SV50, but you shouldn't need rings as large as the 60mm finder requires.

The finder scope is about 1.5” above the surface, but that includes the height added by the shoe.

Thanks! That helps a lot
