The objects you want to chase would no doubt be better served by a larger scope than I'm using, in which case I'd say it swings in favour of the 1600. The reality of the conditions in SE QLD the majority of the time means that we'd be really lucky to see any improvement in resolution with the smaller pixels of the 178/183, and they're a bigger hassle to use

Thanx, Dunk, taken onboard champ
I am also considering that my SkyWatcher Newts dont have the best optic surfaces about either, prob 1/5 - 1/8th wave; not 1/15 - 1/20th like the finest out there.

going up crap-creek without a paddle at best of times,
Overall,, getting through the LP with mono, & the extra resolution with out the bayer matrix should tickle the armpits enough
