Osc
Sterling advice as always folks.
Another reason to get an Osc in my mind is that I have a cooled 60 da and it must be at least 1.5-2kgs, which is fine for the refractor but it does worry me in the newts- changing focuser would be an option. A nice 500gm Osc would help things. Another thing is the length of the imaging train on my mono FLI- I have camera, filter wheel, OAG and focuser which sticks out the back of the refractor a country mile!!!
