Subject: Question about Deep Sky techniques at Cedar Key
I just got back from Cedar Key, FL and took my first deep sky photos
which can be seen at
http://gallery.mac.com/davidbleser#100231&bgcolor=black&view=grid
They were taken with a CGE 1100 at f/6.3 using a DMK21AF04 camera and
Astro IIDC. My FOV is barely large enough to contain m27 as you can
see. Obviously I need a larger FOV and the CCD in the DMK21AF04 is
too small for that.
Would you recommend that I purchase a monochrome DMK31AF03 with more
pixels (but slightly smaller pixels)? I assume the smaller pixels
would result in longer exposure times than the DMK21AF04. I can't
seem to find many deep sky shots posted with that camera.
Or should I, like Milton, sell the farm and get a another camera with
more pixels and sensitivity? I would prefer staying with the 1.25
inch cameras. Milton has spent plenty of time considering these
issues but I know his modus operandi. He slaps a Peltier cooler on
every camera that comes into his house. So this confuses the non-
Peltier modifiers like myself when I try to interpret his photos.
The 6 megapixel StarShoot Pro looks tempting but I would like to
continue using Astro IIDC and not jump into Windows with BootCamp on
my white MacBook.
