I changed my mind and decided to go for the 8" purely because it's all I will be able to afford for a fair while (another baby due in 5 weeks!
) but I've just checked the Andrews website and the 8" is now $499! Must have been a typo. Anyhoo just wanted to say thanks again to you all as you've been instrumental in my choice of upgrade. Next stop: dark sky sites!
Cheers
Wade
