This site at which we saw so deep is known for both bad seeing and
scintillation (which are two different phenomena).

In its "50 & 25 years ago" column, the August 2004 "Sky &Telescope" references
an August 1954 article about research showing that seeing and scintillation are
independent phenomena.

So to all the budding backyard observers out there, don't assume the seeing
will be bad just because the stars are twinkling. You might miss an excellent
seeing night.


I have never seen in quite a number of years good seeing with high
scintillation. Conversely I have seen very bad seeing with virtually
no or little scintillation. Few odd times I had decent seeing (5-6/10)
with noticeable scintillation. This spanning three continents and tens
of different locations.
