I can second this.. the extension tube also cuts out a lot of stray
light input.I make mine out of 1mm thick modelling plywood
from model shops.This is steamed with a kettle into a tube then
glued together and painted Meade blue outside and matt black inside.
Costs about 10 dollars not the rip off price for the commercial
versions.
