Hi Stephen good luck !
The second list is much harder than it looks.
A couple of nights ago I had a go at Rho Cap when it was near the zenith. The scope must be collimated perfectly, the seeing very good and enough magnification to cleanly show the airy disk and a couple of rings around a star like Acrux, for example.
Despite separation of 1.8 arcsec I had to push the magnification up past 300X - even had it at an insane 500X for a while - to be sure I could see it split cleanly, given the difference in magnitudes.
So these really are a supreme test of scope and eyeball.
I’ll add that some of these doubles have noticeable colour differences.
