Hi Dennis,

just following up on your recommendation on wheels and track.

I’ve looked at the site the wheels come in three sizes and at the price you quote I would think these are the 50mm diameter V wheels. The other diameters being 60mm and 78 mm  se

My Observatory is 3.6 x 4.2 m. with a Pent roof which is felted. Based on your experience which sized wheel would you recommend.

The track you mentioned has a round rather than inverted V guide.  Does this except the V groove wheels.

Many thanks,

Eric
