Upgrading your Meade ETX focus for $0.01
Focussing your Meade ETX90 can be a bit of a drag, especially when using high magnifications. That’s not a design flaw, it’s just the trade off for an affordable package. This is how I fixed it. I took an ordinary clothespin/clothes-peg and reshaped it with a Dremel Power Tool. It took me about ten minutes to get it right. Modification is not necessary, but if you do it you will be rewarded with far more free movement. With the modified clothespin, vibration-free focussing works like a breeze. Give it a try!
