The best challenge is when that little white dot is hiding in a diffraction spike. That's turning the difficulty up to 11.

Great to hear this , as Iv'e never looked at Sirius in above 7" , though next time I will try in my 10 sct, as I thought the central obstruction might hamper my attempts.
So it seems aperture and seeing might be the keys here ? and not to worry too much about getting over 200x , unless using small apertures.
PS: I've heard of people rotating there tubes now and then because of the spikes, not so easy in the flex tube though, to see if the PUP is being masked, and maybe this is what happens to some observers!
