I have read this, the difference is that with such a large scope cool down times are greatly improved by the use of Pyrex glass, with its low CoE. plus the use of a Crayford 10:1 focuser instead of the Crayford style focuser! thats what im looking for. Also in saying this the difference with supplied peices, i have read in alot of places that the cheaper eyepeices that don't use the ED glass arnt that great. My current telescope was given to me and its a 100 dollar dikies special! when i got it the collimnation was up the creek the thing had back lash like a car crash victim and to boot the cover for the OTA was never put in place hence there was a layer of dust that could rival the best attic's! :S So i want something that is going to be.... Good not just alright!
ive suffered enough
