Wow! These are amazing. This will exceed his (and my) expectation massively. If he's able to take photos like this with the Heritage 100p, he'll be absolutely made up.
I've added the scope, a moon filter and a planisphere to the basket. I can't see a phone adapter though. I've asked the question of their support team. All he'll want to do is get the images as photos. I'd assume, in my astronomy naivety, that this was all a "phone connection" meant, so apologies to those saying I won't get a phone connection at that price point. If the adapter than allows him to take photos is available, this is what I meant
