这个拍摄者的话!

I used a set of adapters to fabricate a sturdy connection between the 10D body
and the
PST eyepiece holder. Here's what I did:

1) I used a UO 18 mm eyepiece, unthreaded it off its 1.25" cylinder, and
threaded it into
the internal threading of an 1.25"nosecone-to-T-thread adapter.
2) A 40 mm long T-threaded extension tube connected the above assembly to an
EOS-to-
T-thread adapter.
3) The whole assembly went into the camera body, and the nosecone was inserted
into the
PST.

With the 40 mm extension tube, I got a magnification of about 3.5x, and ended up
with a
solar disc of 12.5 mm diameter on the CMOS sensor of the 10D (its dimensions are
about
15.5 x 22 mm). This assembly does reach focus when the nosepiece is fully
inserted into
the PST, and at the given magnification.

I will, weather permitting, try several other eyepieces and see if I can further
improve
contrast.

Even though the 10D is a rather heavy camera body, the connection is very sturdy
and the
image is well-centered.

> I've been using my Olympus digicam but find it difficult to focus since it
isn't an SLR. I've
been wanting to get either the Nikon D70 or Canon 10D and this could push me
over the
fence.

I would consider the 300D instead. Cheaper and lighter , but same chip as the
10D. One
word of caution: Some of the CCD or CMOS chips show ugly interference fringes
(Newton
rings) that are formed in the chip cover or IR filter in front of the camera
chip when
illuminated with monochromatic light. Some cameras have them, some don't. Mine
shows
a few very minor fringes that are easy to process away. I do know from
discussions on
digital_astro that Paul Hyndman had trouble with Newton rings in the past...
maybe he can
give you more details?
