Well, now I've done it. I put too many ventillation holes in the
mirror cell end of my Starfinder Dob, and the star test now shows a
poorly supported mirror. Not to worry though, I'll fix it.

This is just a caution that anyone considering the Alan Adler fan
modification might want to consider. Turns out there is a point at
which the sonotube becomes sufficiently weak to deform the Meade
Starfinder particle board mirror cell.


I followed the instructions given in the same article with my 12.5 inch
Starfinder and had NO problems. The 5 exhaust holes are about an inch
in diameter and spaced perhaps a wee bit more than an inch from each
other.
