For anyone with troublesome internal tube reflections, you might want to check this out: https://www.ko-pro.black/flocksheet/.
I have no idea how durable it is, or whether it is fit for purpose (I haven’t tried it myself), but it appears to possess exceptional light absorption properties in the visible (and IR in the case of the best version).
Amazon usually sells this, but I think there’s a supply issue currently.
Just thought I’d pass the information along for anyone who might be interested.
