    Default 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.
