Read the articles and tried a few things. Here's something that's missing from the info.*
There's no point in trying to keep Sirius A *just outside the eyepiece if you use a Dob. I.e a human and not a computer to guide. It just can't be done at high magnification (300 x in my case). No need to explain if you've tried it. So keep it in the middle.
Focusing on Sirius only works up to a point. Fine focusing is easier if you try to get the defraction spikes as narrow as possible because A is too big and fuzzy. It's essential really because Sirius B is extreamly close to one of the spikes. Well it is on mine anyway. My spider goes east west north south and B is just next to the East spike.
It's such a fun binary.
Have a nice night, Markus.
