Great thread, extremely useful. I have just bought a SkyWatcher SkyMax 127 AZ-GTI. Some years ago I had a Celestron NextStar but got fed up wasting valuable observing time trying to master the set-up procedure. I 'reverted' to a 200mm Dob with no tech aids and have never spent so much time actually observing. But finding many DSOS has been problematic so I am trying again with GOTO. I have considered adding StarSense (still hoping for a fully self-setting scope) but am thinking more than twice having done a little searching on the forums. Anyway, just wanted to say thanks to NC for his very valuable post and all the resulting discussion. Wish me luck! ?
