Will be interested to see some images coming out of the ED100, Kevin!
My point above was a more general one that me asking advice about which apo/mount/imager etc. to buy. It could apply to any setup (DSO, planetary, visual, videoastronomy, AP, etc.). I just wondered if people had accumulated a particular consensus in these different fields.
Matt's point about buying for the long term is a good one. That is why I invested in top quality eyepieces (Naglers, Panoptics, PowerMates) - I figured I was buying 'em for life, to service any OTA I might present them with!
