You have really got to go some to better those Meostars.... you have the same ones as me.
Sure if you want wide FOV, ar flat field, then you can get an improvement. Neither quality is particularly on my hit list for binos.
I sat checking my Meostars against Pures side by side a while back. It was only the FOV, and the 'Flat' field optics that were noticeably different. And that's where the money goes!!!
I actually preferred the view throught the Meoptas, it was nicer, more saturated, quite 'Leica like'. Sod accuracy🤣🤣.
Looking at some distant trees I could see no difference in centre field regarding resolution, and I'm lucky enough to have what is considered perfect vision on my last eye test.
You could well find yourself disappointed in spending a thousand pounds more, achieving very little gain, and missing a nice trip.
It would probably serve you well to go to an optics shop and put your Meostars directly up against some new stuff.
You may well come away very pleasantly surprised, as I did, or you may find that the £1000 upgrade is worth every penny.... All different aren't we!!
