The Celestron computerized alt/az mounts are my favourites to use - easy to align, easy to find objects and then let the mount track. I have a Celestron Evolution and Celestron CPC converted to single arm. The Evolution is particularly easy to set up as it has the internal battery, the mount and tripod stay connected and I leave the hand control plugged in.
The computerized Advanced VX is also dead easy to use but needs a few more trips to set up.
On occasions it's nice to wander around with a simple push-to mount though. It's also a lot easier to find things manually at a darker site since the brighter DSO's are visible to the naked eye giving more reference points.
Lately I'd noticed less difference between filter and no filter for viewing DSO's and everything seemed a bit brighter, then one night I was out the front of the house and noticed that my closest street light is blown - hoping they replace it with newer, less polluting technology.
