Tak LEs and H-alpha
Has anyone used these Taks with an H-alpha filter, and what are your
impressions compared to other eyepieces? The 7.5mm is my favorite at
night, but I'd like to find out how well they hold up to Cemax
eyepieces for when my PST comes in.

The Tak 7.5 is one of my favorite eyepieces, too. Unfortunately, its
focal length is too short to be useful with your PST. I've tried it and
it is too short for my maxscope 60 as well.
I only have the 5 and 7.5, so can't tell you if the longer Tak eyepieces
will work well. I suspect they would be just fine.

Well, I have used a 6.4mm Meade SuperPlossl in the PST (62.5x), and it was
about as high as I really wanted to go with that instrument, although I could
still see a great deal of detail. With a dark cloth shroud, it wasn't too dim
an image, although I could still see about the same level of detail that I had
seen with the 18mm CEMAX and the 2x Barlow (44.4x). I once pushed the PST to
80x, but at that point, things seemed to be a bit on the dim side. Clear
skies to you.

I was interested in what David said above, and this time tried the TAK
LE 7.5 in a really transparent sky this morning. I was wrong, and David
is right- the eyepiece is NOT too short, and can give really spectacular
views. BTW, the Sun has lots of pretty detail today in H-a.
