Hi and welcome Kingy , Good words of wisdom there from Poita , A smalish good quality refractor on an eq6 is the way to go for astro photograghy. Most of the top photos seen here and around the world are taken with kit like this
.
Your new Canon is a good start . ..
Oh yea , by the way
, I may be selling my really nice Saxon ED80 with 10 to 1 focuser soon , these scopes are probably the best beguinners/intermediate photographers scope choice world wide , good quality, great performance at a really good price , a perfect all round scope also capible of top visual performance .
Brian.
