I used a nice 29-incher for over twenty years, and am now enjoying my 36-incher. Well, you will be able to pull in a lot more stuff; aperture indeed rules, provided your skies are nice and dark. Coma corrector, of course. Transportation... I'd say to seriously, very seriously consider finding a semi-permanent observing site... even if it means just rolling out of a shed. Toting the thing afield setting up / tearing down gets very old very fast. Imagery --- put it off, preferably forever. If you feel that you must image, consider EAA or Night vision to e.g. Smartphone.
Enjoying the capability of biggish aperture is the goal. Anything that can defuse it becoming a chore will be to your benefit! Tom
You can't get much better advice on this than from Tom. I read up on his threads dealing with large scopes and I soaked up invaluable advice and recommendations.
The only reason I have a 24" SpicaEye is BECAUSE it is housed in a rollaway shed that our contractor built to be extremely easy for me to use due to my muscle disease. Open the doors, roll the shed back and it's ready to acclimate.
I went all out and got the GoTo with Argo Navis, which sometimes I use and sometimes I don't...it depends on what I will be looking at on any given night...and there is a LOT to look at.
For me personally, since my observing time is limited due to leg fatigue, I can pop off 20 objects in an our with GoTo. On the other hand, I may want to spend 20 minutes observing a glob, in which case the tracking is invaluable for me.
M57 with the easy central star and bluish-grey appearance, M13 with more stars than I know what to do with, Stephan's Quintet...the list goes on and on.
We have had a lot of bad weather so I have been saving M42 for a top notch night of transparency because I know my socks will be blown off.
Also be prepared to be seeing limited a lot though! You need exceptional seeing to be able to crank up the magnification to take full advantage of the mirror size. I've had mine for about 6 months and the most I've been able to crank it up to is about 400x on globs. The planets are simply too low for me to be able to get the kind of views I can get with my TEC180, because of the mirror size.
But I am not complaining in the least. I got the 24" for DSOs and that is exactly what it excels spectacularly at!
