Morton / Alex
Thanks for the replies.
The only reason I mentioned wrong is buying another scope when I've already got a GT-71 & 81 and haven't even started astro yet. As you say with the LZOS 105 I can't go wrong.
Also lucky that Barry C. had a Riccardi 0.75x Reducer / Flattener so I'll have that to take photos, and give me the option of 487mm at f4.65
Cheers, John
