I built a new rocker box for Molly the 16 inch Dobsonian telescope today. She has been top heavy and required a counterweight (an elastic cord) since I built her about 20 months ago. The new rocker box is 4.5 inches taller which allowed me to raise the bearings up and shift the 24 pound mirror back by the same amount. Obviously I’m not done, there is stain and poly to do not to mention attaching laminate and the ground board but I think the problem is solved. The picture shows her tilted nearly horizontal with an eyepiece and everything with no kind of counterweight and she handles it just fine.
