I have gotten really good at "focusing" on 405, to the point where all I see if the pinprick spot, no blooming. If I just over focus to a blank space closer to me, in between my eyes on the spot, it will make the spot very crisp. I can see it so clearly, that I can even see the smoke of whatever it is focused on, coming right from the spot. No over saturation, blooming, glare, it's perfect.
Maybe you could try that. Just make yourself cross-eyes basically, focus your eyes on an empty space between you and the spot. If that doesn't work, go beyond the spot.
