As one can expect, with this combination, it's natural to look for something bigger... The bottleneck is on the mount, so what's the bigger aperture that I can get with my current mounts? C5 would be marginal, a Borg 101ED might be lighter but longer... maybe a 90mm Maksutov?

On the other hand, maybe it's wise to switch the NGF-CM to something with longer focus travel?

Right now my setup is obviously optimized for solar observation and wide field imaging, visual observation is pretty limited due to the small aperture, similarly planet imaging is limited as well. An upgrade to moderate aperture like 5" would be a nice step but then it might push the mount a little bit.


What I love to do?

Over all these years, I guess that I know what I really love to do and what I can really do. First of all, when imaging is concerned, I will love to do solar/lunar/planetary and also short exposure (several minutes) wide field portable imaging. Secondly, when visual observation is concerned, I love wide field scanning for brighter deep sky objects.
