This is a double barrelled question, but being as it is equipment related, I thought this would be the best place to post. I apologise if it is not.
I am very new to Deep Space Imaging and I purchased my equipment from a well known retailer here in the UK. when I asked about what dew heaters they recommend, the guy said he recommends their own brand, and so I purchased them.
Well, attached are the pictures I have taken of what I received, but I cannot figure out how to power them up.
I assumed that they would plug into the ASIAIR Pro I purchased from them, but they are the wrong connection.
Can anybody advise me of how to power these up?
The second part of my question is,
At what temperature should I start using these?
It is around 16-17 Celsius or 60 Fahrenheit at night where I am, should I already be using them or is it not cold enough to worry?
