Hi Gents, Mate i had a PST with an SM40 attached to it, the views were exellent, although you did notice the sweet spot,no big deal though. I have inquired about the Lunt (above) I went in to Cloudy Nights in America, and talked to "Steven Ramsden" he reckens that the 60 mm Lunt Double Stacked @ 0.5 angs, with B1200 Blocking Filter is the way to go, i have heard that this scope is supperb in all way's. I will certainly get it as soon as i can. My friend owns a Coronado 60mm at 0.7 angs, the views are exellent, prominances are exellent, however you can't really see Fillaments very well, that's because it is 0.7 and not 0.5 angs. apart from that this scope is made perfectly. Steven did enquire about the "Daystar Penta" @ 0.5 angs, he evidently had an enormous problem with this scope, and the people who made it, they didn't get back to him straight away, he had to wait god knows how long to get help and a reply.He said it was made well, but could not to any focus at all, and when they got around to change it, that one was big trouble as well, he was not impressed at all. with the scope and Daystar. If you go into Cloudy Nights you could see his comments on these scopes.
