Hi Craig
Don't generally need dew heaters here until Sept/Oct when it gets below zero at night
All these issues you mentioned are indicitive of RC, Schmidt Cassegrains and Newts, dew can hit anyone so don't be put off by that and collimation as all reflector type scopes need this done regularly.
Th reflection artifact may be something simple to fix and we are working on that.
Cheers
