No secret John and no previous post to have missed, though not really using it so much i found myself missing the Tal100 after parting company with it, but the plan had been all along to look to getting more use from the 150pro skymax, hence selling the Tal plus getting the ED80 for a bit of "jack of all trades", the ED80 really is a scope than is jack of all, master of none, but there is a lot to be said for a 4" F10 so i will be purchasing a Celestron CR4 OTA from a very kind member and good friend on here, this will give ED80 for grab an go, some very basic deep sky imaging, a 4" F10 for Lunar imaging and observing plus splitting easy doubles and the 6" Mak for tight doubles and general high power Astro including Lunar webcam imaging and planet observing
