Stock 2 speed focuser on SW black diamond ED120
I have recently bought a new SW BD ED120 , has anyone had any experience using the stock 2 speed focuser with this telescope for astrophotography ? I have tried it visually using the 2" diagonal and 2" eyepiece supplied with no sign of flexure or slippage. These two items together weigh about 900 grams compared to about 800 grams for my canon DSLR.
I would appreciate any advice , regards philip.
