DIY barlowed laser collimator

I’ve been reading about barlowed laser collimators and decided to DIY one.
I cut the center out of a cardboard circle and pushed that into the bottom of a 2” GSO 2X barlow and inserted my cheap SVBony collimator into the top… I think it worked…
After adjusting the primary mirror, the reflected circle stays in the centre of the reflected image (on the cardboard) even when I wiggle the laser.
Woo hoo… I guess??
Any thoughts?
