I will send a link to him to review what has being said. I guess it's more of what his main interest is. Either mostly visual with a small amount of photos, or more a 50/50 split. Since i don't think he is interested in DSO imaging. I would have thought either the evostar 120 ED, for mostly visual. Or a mak or SCT, for more mixed usage, would be better. The money saved on scope could go towards a good mount, that would probably cost less than the esprit 120 alone. If he wants to view DSO, he can always look through my 8" dob to see if it interests him. Unless he gets something like a 8 or 9.25 SCT. I am unsure on the budget that my cousin has set. Knowing that he is considering the esprit 120, could be up to around 3k.
Thank you for all your input. Hopefully the info will help in choosing a suitable setup, and get me looking through some different equipment to compare.
