It also carried the load of the camera better. I should note that the Questar was over 25 years old and the ETX brand new. No matter where I set up the Questar, I had a fine observing experience. The metal frame and strong drive motors and gears handle camera loads nicely with only a few problems. Another difference I noticed with different brands of telescopes is the quality of the drive system.
Some drives are clunky and have troubles holding the target steady.
They tend to be noisier than the higher quality systems. So if you can afford a more expensive brand, they are worth it. And it is worth shopping a while. Good deals will sometimes come up through astronomy club members or other contacts. When you buy a telescope you often buy it for life - get a good one.
