    FR6.3, gives you two scopes for the price of one

    chair

    Don't get a crayford or any other long focuser for your SE mount - you will hit the mount when viewing near the zenith.

    quite a few folks over on CN love star sense, but you really don't need it with the SE.

    Get a really good external battery as mounts can be very fusy about the voltage they receive.

    How about dew heaters? Is that something I should consider or will a dew shield be enough? At this point I won't be doing hours long exposures of anything.

    I prefer a portable battery operated hair dryer. I have dew heaters that I should unload.

    Any recommendations on a battery? I have the Celestron power tank, but that uses the AC port just like the wall adapter. The internal battery compartment is for 8AA's or something like that. I hear the mount eats batteries up.

    What are the heaters even for? Dumb question, I know. Are they placed around the front lens and primary mirror?

    Definitely a yes on something heated to control dew. I use a 4 channel controller and dew bands on my C8, but the hair dryer will work fine also.

    Try a dew shield first the heaters take a lot of power , on my C5 with a home made dew shield I have no problem for many hours on the C5, its 150mm long so almost half the length of the scope and diagonal !

    This will run your scope and a dew heater if you choose to get one.

    The heater adds enough heat to the front lens to keep dew from forming. Mine is right behind the front lens assembly. There are also dew shields with built in heating elements.

    Seems like a hair dryer just adds another task you'd have to monitor.
