Thank you both, for getting back to me, and for the welcome, @Floater. I didn't receive any notifcations, but as you noticed, I've only just joined, so I'm sure I'll sort that out!
@Peter Drew It looks like my 32mm plossl gives me 89x magnification, and that seems to be the sweet spot for me. The 26mm plossl gives me 110x, and 80% of the time, it just degrades the image through equipment. It's only with really good seeing that it'll give me fantastic views. I've tried my 40mm and even a 55mm plossl (the most useless eyepiece I own), and the field of view through the Quark itself is just too narrow. Not as bad as the Coronado PST I had before though.
I should probably expand a bit on my slight reticence to shell out huge amounts on a quality bino viewer. It's not out of the question that I do shell out (well, maybe not _huge_ amounts), but I've read that some people just don't get on that well with binoviewing, and I happen to have a lazy eye which might make it troublesome. My presciption isn't wild, it's +1.25 on my left eye, and +2.5 on the right. The optician says that I'm probably more like +4.5 on the right, but he wouldn't prescribe that for another 10 years or so (when I get past half a century!).
I thought about buying a really really cheap binoviewer just to try it out, but I decided I don't want to go so cheap that I end up not liking it because the equipment is rubbish, not because my eyes are rubbish, and not being able to tell which of the two it is!
My lazy eye isn't so bad that I haven't used it a lot for looking down an air rifle scope, with both eyes open, so I'm quite hopeful that binoviewing will be everything it's cracked up to be. I can see ok with the bad eye, but my brain prefers prioritising the signal from the good one, even if that signal is just of the darkness behind my eyelid
I'll keep on deliberating. Maybe something will come along that seems like it was destined to injure my bank balance!
