Hi John, and
.
I also started with the 114mm newt, it inspired me to go bigger and better ( and spend lots more money ) but it was an eyeopener in my LP CBD area all the same.
I'd suggest that part of your stabilty\wobbly problem comes from the tripod as mine did. I hung a small anvil of about 5 kg beneath it and it made a big difference to it's viewing stability. It was good enough for me to add a small RA drive and camera and get my first tracked pics.
If you are building a new house you probably won't have time to do some of the other mods I did to improve the scope but the weight underneath does make a difference.
And I did spot my first galaxy with it ..
