Great series Richard. Operating two scopes at the same time sure helps to
get the exposure times you have here.
As I am faintly considering to buy a camera with the Kodak 8300 chip I
would be interested to hear your opinion on it. Does it produce "noisier"
images than the 4022 chip? I saw a post by Terry Platt in the SXpress
Yahoo group

not that I have seen Stefan. I measured the read noise to be less than 8 e-.
Considering that is for a 12MHz download that is darn good. It may be lower
than the competition and they most likely are running 1 or 2 MHz. This guy
is downloaded very fast.

I was expecting that Eline image of the IC1396 area to be noisier than it
was. It was pretty clean: I only did my usual SGBNR very light noise
treatment: nothing out of the ordinary.

The KAI4022 has some nice properties: the electronic shutter makes taking
flats easy.... but it has low Ha sensitivity just like the old STL11000's
KAI11002

The KAF8300 is a full frame and antiblooming but it seems sensitive enough
and works well with the tiny pixels. I got a decent image scale with the
AP155EDF f/7 and really enjoyed using it. I want to try it on the '180EDT
f/9 but so far I have the ML4022 stuck on it due to incompleted projects. I
want to shoot an unfiltered shot of NGC7331 with it and see how it looks
from the AP180EDT f/9 so I may make the change this weekend.



where he said that he tested the 8300 chip and thought it's cosmetic specs
were not good enough compared to the 4022 chip. I shy away from the 4022
chip because it has such a low sensitivity in Halpha.

If you ask me, I think Terry's excuse is a convenient one to prevent him
from having to deal with a mechanical shutter. Don't all his cameras use
interline chips with electronic shutters? Has he ever built one with a
mechanical shutter?
