I always enjoy going off the beaten path a bit. Sure, the old standards are great, but it's fun to broach unfamiliar terrain a little, as well.

The skies are plenty dark here. Light pollution is not the problem.

I see in this month's "Binocular Universe" that Phil Harrington found M52 and M103 in 10x50 binoculars. I can not yet find them in my Nikon Action Extreme 8x40, yet comparing the surrounding stars to my charts, am confident I am looking at the right part of the sky. How do I decide when to keep honing my skills, and when to buy a larger binocular with more magnification?
I struggled with them for years and years in 10x binoculars. M103 is the easier of the two IMO, its main problem is that it's just so small - looks more like a chance alignment of a few stars than a real cluster, in that size instrument. With M52 you're looking for its unresolved glow with averted vision.
These targets are both MUCH nicer to look at with 15x binoculars. Let me assure you, you will NEVER regret buying a quality 15x binocular - it opens up a whole new sky to you. In very good sky with a mounted 15x binocular, expect to see partial resolution in many clusters which in the 8x - 10x instruments are just fuzzballs: M37, NGC7789, M11, M67, etc. etc.

My sense is that, absent skills I do not yet have, the right bigger binocular would radically aid my viewing and learning.
What a rant. Sorry.
Any other recommendations for favorite binoculars to reveal M52 and M103 to someone who can not yet find them in his 8x40? I'd bet 15x70 will prove popular as a sweet spot between making objects sufficiently large and bright to be visible, while also offering a wide field to ease actually finding them.

Do you want to take this conversation into the binoculars forum? Surely other people could have suggestions. We're sort of hijacking this thread.
