Hi Columbus,a little advice on power ! the 17aph power tank will be fine for your mount but you will need an other battery for a due heater come next winter . I have found that the best option for this is a Deep Cycle battery from Super Cheap Auto's .
They have 75 aph DC for $149.00 , this will do for all your power needs (learnt this the hard way)
so If this is the case ,you can save your money on the Celestron Power Tank.
