Thanks for yor kind comments.
Yeah Paul I'd never seen spicules before and my jaw dropped when I got the first view thro' this beast.
Matt I call it a PST-B90. It is a Badder D-ERF 90mm energy rejection filter. Thats on the front of a Celestron C100ED f/9 refractor. At the focuser is the box of the PST including the etalon piece, prism and built in BF5 blocker. Most modders are getting rid of the box altogether (thats the "B" in PST-B) and using a BF10. But I'm currently saving up for a BF10 at the mo. So in effect I have a 90mm Halpha scope for about a tenth of the cost. Will post an image of it soon.
