Has a bigger payload then the heq5 also belt drive for less error. Seem like a perfect mount from the reviews and what people have being saying about it. I wouldn't make use of the a/z daul scope function but if you did it would be a big plus. Lol can see a few cheap used eq6's flooding the market soon with this out. The only problem is the price is starting to get into g11 territory and for imaging on would go for one of them
Though for what your after its the best option since you want to use eqmod
