Astrophotos Taken Through A Meade ETX 90
|
|
This page presents lunar and planetary photographs taken with a Meade ETX90, using a modified Quickcam Express Webcam and a 2x Barlow. Most of the images are
single frame captures. Those made from stacked frames are so labeled.
These pictures are first time efforts with the Meade ETX, but give some
illustration of what can be easily accomplished. Most were taken with my Quickcam Express Web
Camera, and some with my newer Celestron NexImage web cam astrocamera. The
moon images are not representative of the best the telescope can do, but
are pretty close to that. The Jupiter photographs are not as good as I hoped,
but again, near the best this scope can do, at least with the
Quickcam.
Stacking planetary images would give far superior results, but on these
first outings I didn't get enough images to do that. The Saturn photo was taken
at prime focus because of the dimness of the planet, and then enlarged. To
learn more about how stacking images can give better results, check out the Celestron NexImage
review.

Personal Notes
Though the pictures on this web page were taken with a modified webcam, they
could have also been obtained with a digital camera mounted behind the
eyepiece. With a digital camera, you don't need to haul a computer out to the
telescope to control the camera. I've constructed a simple mount to hold my
Fuji behind the eyepiece, and will soon be adding photographs taken with that
method.
