Thank you very much everyone for your input. It is a lot of information to process! Given i am a beginner.
I will have a look at the Vixen (looks to be very good value for money!) and keep my eyes peeled for used ED80 and ED100 as well. I'm assuming if i want images to not be upside down, my easiest choice will still be a refractor.
Also, will it be hard if i want to mount my Canon 5D Mark II or Canon 70D on the telescope? Thanks.
