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. The ERF is an...

Re: Etalon PST problem - NEWS
In my present PST I noticed that banding (due to tilt) is different. Sometime, when only a little amount of tilt required to get to the H-a core, almost full sun disk seen in Ha and more or less uniform. At higher barometric pressure and lower temp, the etalon require a severe tilt and as the result...

Pupak, Nothing wrong with the etalon itself. The picture you see on the solar disk is "banding". It just due to too much tilt required to come to the Ha CWL. This given etalon require too much tilt and you can see the results of such too much tilting - sponges are damaged. I have tested MA...

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