Outstanding on PST
I had been using primarily a Tak 7.5mm EP on my PST, which seemed to work nicely. When I double stacked the PST, that EP was no longer adequate. I purchased this Lunt after comparing it to some Lunt fixed EPs and also to the Pentax zoom of similar specs. Much to my surprise, on the PST this is far sharper & brighter than the Tak EP, even with the Lunt at 7.2mm; it is superb at all zoom settings. It has an adjustable eyecup, and overall it is very well made and surprisingly small.
