Baader Hyperion 8-24 Zoom
I purchased this eyepiece mainly for h-alpha solar observing and fortunately have had some opportunities to observe through it during some recent active regions. I found the stability in focus very reasonable and the click-stop to be very smooth. Having owned a cheaper zoom eyepiece in the past I am very pleased with this Hyperion, I recommended it to a fellow astronomer who has ordered one and found after purchase that two other fellow astronomers prefer it as a main eyepiece.
