Subject: OT: Canon 20D Astro Camera


Hi all--

A friend, Jack Estes, in my local club in Austin, TX, works at a large
camera store and got notice of a variation of the Canon 20D modified for
astro use. Here's the details:

Here's something that all of us might find of interest. Canon announced
Friday a specialized Canon 20D digital SLR that is especially suited for
astrophotography. Follow the link and read the promo.

Thus far it's only available in Japan, not the US market.

Used to be various film camera manufacturer's made specialized versions
of their SLR cameras for our market, i.e. Nikon F, F2, and Mirandas.
This is the first digital SLR I've heard of that isn't specifically
aimed at the general public. Perhaps that's a sign of a maturing market.

From Canon:

A 20D-based new digital SLR, specially modified for astrophotography,
has been announced in Japanese market. It's based on the 20D with the
modified sensor chip to optimize the optical characteristics for
astrophotography.

Q1: Are you planning to introduce this product in US market?
A1: We're planning to do so. We're currently figuring out the
potential market size, etc. Any details (price, shipment, etc.) are to
be announced later.

Q2: What does the camera's name mean?
A2: While the base camera is the EOS 20D, the "a" stands for
"astronomy" indicating that the camera is geared for astrophotography.

Q3: What's the difference between this camera and the regular EOS 20D?
A3: There are two major differences. One is the optical
characteristics of the CMOS sensor, another is the availability of "Live
View" mode. Here are the details of the 2 items:

1. Optical characteristics of the sensor are optimized
forastrophotography. The camera's
sensitivity to a specific wave length (H-alpha lines; 656 nm) is higher
than with normal digital cameras (about 2.5 times higher than with the
EOS 20D). As a result, reddish, diffuse nebulae can be captured more
easily and clearly.

2. Live View is a special mode to view the image on the LCD monitor for
precise focusing, by means of locking up the mirror. One setting for 5x
magnified view (about 4% of the live image at the center is displayed
full-screen on the LCD monitor), and another for 10x magnified view
(about 10% of the live image at the center is displayed full-screen on
the LCD monitor).
