Thanks for the replies all
All good information. And that other thread was an interesting read too.
I'd be a little disappointed if the kids responded with a "meh, can't see anything but blobs"....but at the same time, you never can tell what will inspire them, so I'm happy to try things out with them. I guess also I'd be happy enough doing it alone if it doesn't take their fancy.
I couldn't quite decide whether to spend the cash or not....but having read the replies, I think I will.
I'm on the edge of an urban town, so dark skies will probably be an issue at home. Plus, lots of tall trees around the garden, so the views can be obstructed a little. But, my parents are moving to a nice dark spot in Norfolk, so some good opportunities no doubt there.
That's good to know. I'm guessing the 150P Flextube will be very close/same quality as the 150P?
Whilst I'm here, are there any "must have" additions/accessories I really should think about from the word go? I've already seen a couple of cheap simple mods (shroud + PTFE tape on the viewer) for the Flextube that look like they're worth doing.
Thanks
Patrick
