I find that magnification around 100x work best with my scope.

I think the Pup is pretty easy with a 3" to 5" aperture at just 70-100x. I don't think high magnification is needed if you have an extremely high contrast, well-baffled scope. I plan on trying tonight with a 60mm.
I think the experience of the observer may have something to do with the difficulty of splitting Sirius or other double stars. I very seldom observe double stars. At home, I like to concentrate on the Moon and planets. At my dark site, I mostly observe galaxies, nebulae and difficult open clusters.
So for me, double stars are an afterthought. I very seldom bother with them. Even attempting the Pup on that night was a fluke. And the idea of trying to split a double with the lowest magnification or smallest aperture is something that is alien to my mind. I just don't do it. I was actually trying for the easiest and most pleasing view of the Pup! If I were to become more involved with doubles, I'd probably mostly view color contrast pairs and interesting multiple systems, at least at first.
Now, trying to see the faintest galaxies or nebulae with my telescope, that's something different. I can understand that.

Sirius B reaches a maximum separation of 11.5 arc seconds in 2025.

Mike - with the C6 you mentioned visual observation could get quickly rather boring if you restrict yourself to "faintest galaxies or nebulae" while with doubles you have thousands of interesting targets available. So maybe thinking twice could be productive.

Don't worry. I'll get around to all those pretty and interesting doubles. They aren't going anywhere.

Congratulations on the split! Sirius is one tough nut to crack, and am encouraged by your success. Jim's awful lucky to have those Californie skies, but I'm counting on his luck with smaller aperture instruments. Now if my windy, turbulent skies will calm down for a few minutes.

The colour to me always seems slightly slate-blue, although that may be an artefact of the Mak which always shows faint stars slightly bluer than they really are, according to stella classification.

The only view I've had so far that I have 100% confidence in is one with my 10 inch. In that view it was tiny blue dot that was persistent. I'm sure as time goes by my small refractors will show it.
Yes, that's how Sirius B appeared in my 10" Dob. I've never tried for it with a smaller aperture.
