I tried the SKY-90 out on the EQ6 last night for a bit of fun but in reality has worked out very well and is one very rigid set up. If the legs are extended fully there is no need to use a diagonal and is particularly comfortable with an astro chair. I usually use the EQ6 with my TOA-130 which weighs in at 11.5kg and the mount handles it with ease. For the price, the EQ6 certainly has a lot to offer.
