Hi Andrew;
Just to be crystal clear, Astro IIDC doesn't support the DFG/1394-1
for image capture.
We do sell a driver for the DFG/1394-1 which I and others have used
with BTV Pro (or other QuickTime apps like Equinox etc.) to capture
video clips with - but it doesn't work with Astro IIDC. Also the DFG
are pretty expensive ($350 USD) where as for playing around you can
use a USB A/D converter box for like $30 to $100 USD.
As to stacking and aligning, their are quite a few products on the
market and you should look at Neale Monks great article at
http://www.cloudynights.com/item.php?item_id=1044
for a summary (bottom of the page).

Thank you Milton. That was really excellent info. I think that I
understand now. I can hack around / learn with what I have (plus some
software bits) and when time and $s permit, get a DFG/1394-1e and pair
that up with Astro IIDC to get a high end astro-imaging system.
Thanks

Hi Folks:
I'm putting together an Astro-Imaging system based around my
LXD-55
SN10, the set of various Macs that I own and my Colour
Mallin*Cam (a
sup'ed up security video camera). The Mallin*Cam has only
composite
and S-Video outputs so, I'm using my (older) Sony digital video
camera
to convert from S-Video to firewire. Now I just need to
periodically
grab frames from the video stream (the Mallin*Cam pre-
integrates at a
variety of settable rates but outputs the latest image
continuously).
Astro IIDC only supports IIDC (also known as DCAM) FireWire Cameras.
IIDC is s specific protocol developed so camera manufacturers and
software developers can talk to each other. We both either follow
the
spec or nothing works properly.
This spec doesn't include Sony DV camcorders, Sony / Miglia / et all
DV video converter boxes, Canon Cameras with a FireWire port, DVC
cameras or the PL66x series of PixelLinks cameras - which all use
FireWire, they have as much in common with an IIDC cameras as does a
FireWire hard drive does - which is nothing other than they use
FireWire for I/O control and transferring data.
So... with that background... I'm thinking... this Astro IIDC
software
is purpose built for Astro-Imaging... probably the right thing for
capture and stacking.
The key here is "IIDC", as it's built for Astro Imaging with IIDC
cameras - not any other HW (ie analog, USB, PCI, Ethernet etc.)
interface or protocols.
Only hitch is... I'm way out in left field WRT
the supported camera types. Will Astro IIDC help / work for me or
should I be using something else? What?
Nope - not with that analog camera it won't work.
The first thing you need to get is an Analog to Digital video
Converter like a a DV video box (which is 6:1 compressed and throws
out a lot of color information and data), a USB converter
(352x288 30
fps maxim - compressed to JPEG format), a Miglia type PCI TV
converter box (desktops only) or a FireWire DFG/1394-1 (uncompressed
video which works with color or monochrome security cameras NTSC or
PAL). The Sony boxes don't have real time adjustment of things like
saturation, brightnes,s contrast sharpness, which the USB, PCI TV
tuner or DFG/1394 devices can do.
After that, you can use various products (iMovie, BTVPro, Equinox
etc.) to grab the video to disk and work with it from their.
