Thank you Dave for your reply.
In terms of good and clear images; I'm more interested in visual viewing for starters and photography can come later on once I'm a bit more experienced in this field.
We live in slightly air polluted area, so I'd like to be able to take the scope with me to the desert, where I can have good dark spots to view from. And when it comes to budget, I am looking at anything between £400 to £500. Saying that, I think I should consider the shipping costs of it as well since I live in the UAE and shipping something too heavy can end up costing more than the product itself..
I am open for any suggestion
