    the difference is the aperture size 70mm vs 90mm (larger aperture means more light is collected - better image "generally") 90eq has a longer focal lenght and a better EQ mount, not sure if there is a difference in optical coating.

    As you already know from my other reply I'm a complete beginner myself. But when looking for a scope to buy I simply typed it into youtube to see what people have already put up and viewed with that model in particular. This may be of help to you.

    There is also a great site with forum on www.irishastronomy.org in which a poster on this board previously pointed me towards.
