The wide and sharp field on planetary is what I'm after before I get something great for dso which will be another topic entirely! Even with the 9mm plossl now, Saturn is pretty much through the field by the time the vibration settles and I've only seen it somewhat sharp when I've put the scope ahead and waited and had the focus on. Thanks again.

Regarding vibration: do you have vibration-isolation pads? I have found they cut the vibration time considerably and have been very useful. Meade and Orion make them, although a lot of people experiment with their own.
