I don’t get too deep into the weeds about collimation @ f/5, so I use an old Orion combination sight tube and Cheshire that I’ve had forever for centering the secondary, then an AstroSystems barlowed laser. I just touch up with the laser before I observe but, so far, it’s always still collimated.
FWIW, I used to use the Glatter laser and TuBlug, but I sold them after I sold my last Starmaster over a year ago. I thought at the time that I was done with dobs.
There was a time when I thought I was done with reflectors, but then buying my 10" F5 showed me why I should still want one. I have a 12" too, but it gets used less.
