Re: Small Etalon Improvement For Only $15 USD (13 Euros)

I'd assume the LS40 is nearly identical to the LS35 (see first post of this thread), and the LS40 etalon will be supported equally and uniformly around the perimeter of each etalon plate, and the etaon is seated on the same type of silicon foam rubber pad as the PST and other etalons.

But... the most impressive (for me!) are the images of the frost on the ground! :) Never knew that this is easily possible in Florida!

0,5" seeing is 200% perfect for a 6" aperture! If it was not 100% perfect, then it was far not a 0.5" seeing.
