I had one of these many years ago , the Celectron C102 f10 version , my first real refractor and like you
WOAW!!!what a big step up from what I was using before , these are great scopes for little money .
Glad you had a hastle free buy from Sirus optics , they are very good .
Slightly under rated by many these days ( shame really
) but perform exceptionally on the moon and planets taking 200x plus with ease ( not bad on deep sky in a dark site as well ) .
Enjoy it , it looks like a beauty on that nice mount .
