Great for the price. The service from Horrison's was exceptional. Ordered on the Monday afternoon, here on the Tuesday morning. It comes in its own aluminium, foam lined case along with a few accessories. The optical tube itself is of good quality. Only let down is the 28mm eyepiece, I can let that slide.
