Default Connect a Galileoscope to a camera?

I have a galileoscope kit I haven't done anything with. I also have a
Lumix FZ35 camera. In order to use a camera with the Galileoscope, is
it necessary to have a camera from which the lens can be removed? The
Galileoscope site shows pictures that people have taken, but doesn't
explain how.

Well, the Elias Jordan one could use some words. Like, where does
the "1/25 inch adapter" come from?

But both of these videos seem to involve removing the lens from the
camera, so I guess the answer is "no", I can't adapt the Galileoscope
for use with my Lumix FZ35, because the lens doesn't come off.

Advice Lumix FZ35, Orion Apex 90mm
Hello Everyone, got a few questions and maybe some info that you may need.

I love Astronomy, and Wildlife.
So I got this camera Panasonic Luimix DMC-FZ35. And I'm wanting to get
close to this Red Tailed Hawk, but I can't. So I'm looking at getting this
telescope.
Orion Apex 90mm instead of the one I wanted the 127mm.
The 90mm comes with a mini eq mount. I have been into astronomy on/off over
the years, and have experince with several scopes, 130eq,8" reflector,
10"dob. But no experince with Maksutov-Cassegrains.

So I enquired a little on Astronomy.net

and found out they make a nice little adapter for my camera.
Here is the site. I hope this may help some of you that may be in need of
adapters as well.

Does anyone here have a Orion Apex 90mm? If so how does it perform for
Wildlife spotting, and photography?

I principle it is possible to just point the camera and lens into the
eyepiece and see the image just like your eye would. This may give a nice
image or a very narrow vignetted image depending on the combination of
eyepiece and camera. Every eyepiece has an exit pupil where the pupil of
your eye is best located. Every camera lens has an entrance pupil where the
lens iris appears to be. The trick is to match these up in all three
directions. If the camera lens entrance pupil is too far inside the lens,
this may not be possible. Make sure to put your camera exposure in aperture
priority mode and set the aperture wide open. It will probably work best
with the zoom at widest angle. For something like the moon, you might be
able to just hold the camera aligned to the telescope, but otherwise you
will need some jig to hold the camera to the telescope.

After saying all that, I see now that your camera has an 18X optical zoom
with a maximum focal length nearly that of the galileoscope. I am sure the
aperture is not as large, so the brightness would not be the same, and the
theoretical resolution would be worse, but in practice I bet you would get
better results using just your camera's zoom lens and no telescope.

Vignetting is the worst problem to solve with later cameras. I can
easily take decent pictures afocally using my old Sony P71. But I have
really struggled to take good pictures with my Panasonic TZ7
"superzoom." The Sony has a small lens. The TZ7 a much larger
aperture. I am still experimenting with zoom but it pushes overall
magnification too high for comfort. This reduces the field of view
dramatically. It also needs a very firm mount to avoid "camera shake."

You can hold the camera, even a phone camera, to the eyepiece to get a
picture of the Moon. For other things it is best to have a camera where
you can set the exposure manually. The Lumix LZ35 has only auto exposure,
which can be fooled by the dark background of the sky into overexposing
pictures of Jupiter or Saturn. You can use the exposure compensation settings
to improve the exposure.

Basically you focus the camera on infinity, focus the Galileoscope as well as
you can, and hold the camera steadily to the eyepiece. Some people put the
camera on a tripod. I've tried that, but getting the camera tripod in just
the right position was too frustrating.

You can do manual anything on the LZ35, including manual focus.

Here are some pictures I took of the moon using the LZ35 and some
(possibly ill-chosen) manual exposure parameters:

From what folks are saying here, I probably can't do better with
the galileoscope than I did with the 18x zoom and 1.7x teleconverter.
I had foolishly hoped to be able to zoom the camera at least part way
AND hook it up to the galileoscope.

I'd relied on an on-line review of the LZ35, which didn't mention manual
exposure at all. The Moon picture on the left looks pretty good. I think
that is about as good as you can do. I assume your Galileoscope is the 50
mm refractor that was sold as part of the International Year of Astronomy.
I've got one that I put on an old photo tripod and take to public star
parties for the kids to look through. They enjoy looking through the
little scope as much as the big ones. It wouldn't hurt to try the Lumix
with the Galileoscope. You might surprise yourself. It's just for fun.
Noone is handing out school marks.
