Default astro: m3

The full moon makes it hard to give a full assessment. This one came
from Starzonia. I have assured by the owner of the company that makes it
that the frosting problem has been fixed.

That's an interesting new camera. I've seen some good stuff taken with
it on other forums. Did you get the CCD-Labs version or the Starzonia
version. Seems to be a big debate on which is better that boils down to
very little difference that I can see. CCD-Labs uses argon and
Starzonia uses dry nitrogen to fill the CCD chamber to prevent frost. I
see no difference in the images though argon has better thermal
properties if I recall my chemistry days correctly. Don't think the
difference material however.

I guess I'd like to see thermal control rather than just running at -45C
below ambient or whatever it achieves. Though its dark current is
extremely low so that doesn't appear a big issue. Most don't even use
darks, just hot pixel removal.

So after one image how do you like it?
