When I bought a PST it came with a LUNT solar eyepiece supposedly better for Ha viewing than standard eyepieces.
I sold the PST because it was too limiting and now use the daystar Quark in a 72mm ed.
But I have never seen any difference between the Lunt Ha eyepiece and any other one I use, is it me
I use it because it came with the scope, had I bought it I may be annoyed.
Thanks
