Josh Walawender and I examined the CEM25P when we were at NEAF. It retails for US$898 (without a hardcase), $300 less than the iEQ30 Pro, which is US$1,198. That is a substantial savings given our goal of keeping the price of the whole telescope under $5,000.
Now the big question is whether it can be weatherproofed in a manner similar to the iEQ30 Pro. It looks to me like it can be, but it hasn’t yet been done.
If you’re starting a build, and willing to take a risk and help us with designing the weatherproofing, please respond and let us know.
