Don't know about SEQ, but here in SW Vic dew is a real problem. I have heaters on everything. The shroud will prevent dew on the primary, but I found I had to put heaters on the finder, the secondary and the EPS to make sure I could even use the scope most nights.
A basic 4 channel Kendrick controller is fairly cheap, but the digifire ones are excellent and easy to use.
