Description
:
Whether you currently own a
telescope or are contemplating a purchase, our new NexImage Solar System
Imaging Kit is a MUST HAVE!
NexImage is a complete CCD solar
system imager capable of producing high quality planetary images with
greater light sensitivity and color fidelity than comparable CMOS imagers.
Combined with the NexImage software package, NexImage can bring out
tremendous detail and reveal a final image that will rival those taken with
astronomical CCD cameras costing thousands of dollars more.
-
View and capture live video on
your computer screen
-
Software automatically filters
out video frames most affected by poor atmospheric "seeing" leaving only
the sharpest, clearest frames to be stacked and aligned into one high
quality image
-
Easy to follow quick start
instructions and tutorial with sample video file that will have you
producing quality images your first night out
-
Camera control software allows
you to manually change the gain, contrast, exposure time, frame rate and
color saturation using your PC

REDUCER LENS
Item #94178, NexImage
Reducer Lens.
Increase your field of view by over two times
for wide field lunar and filtered solar imaging. The
NexImage Reducer Lens replaces the 1.25" barrel and
threads directly into the NexImage housing.
FILTERS
Item #94125, UV/IR cutoff
filter 1.25"
This high transmission filter prevent IR
wavelengths from blurring fine detail in your images.
Made with a Ultra-Hard Ionbeam hardened coatings, this
filter has an extremely sharp cutoff at 690nm yet
leaves all the visible red, including the important
656nm H-alpha emission line.
BARLOW LENSES
Double your effective focal
length using a barlow lens with your NexImage for
higher magnification and greater image scale!
Barlow lenses offer an easy, economical way to
increase the magnification range of your eyepieces,
and Celestron carries two of these highly useful
lenses. A Barlow lens doubles the magnifying power of
your eyepiece by doubling its effective focal length.
For example, an 18mm eyepiece used with a 2x Barlow
lens would have the magnifying power of a 9mm
eyepiece. It’s like having two eyepieces in one!
Barlow lenses mount into either your telescope’s
focuser or visual back.
Item #
93326, 2x 1-1/4" Omni
This is a high quality 2x Barlow that doubles the
magnification of all 1.25" eyepieces. This
economically priced Barlow has great features like,
low profile, 2-element fully-multicoated optical
design and blacked lens edges.
Item #
93506, 2x 1-1/4" Ultima
This Ultima Barlow lens is,
without doubt, the #1 choice among amateur astronomers
who want the best performance from their optics. The
Ultima Series Barlow (2x - 1-1/4") is an air-spaced,
3-element apochromatic design with a 27mm clear
aperture. This lens features a very high quality,
fully multicoated design. Amazingly compact and
lightweight, it’s just 5 ounces and 2.75" in length.
Features :
Compatibility - threaded on 1.25"
adapter barrel makes NexImage compatible with most any
telescope.
Versatility – 1.25"adapter is
threaded for standard eyepiece filters and can be
removed and replaced with optional focal reducer lens.
Tutorial - step-by-step Quick start
and tutorial complete with sample video file that will
have you producing quality images your first night
out.
Power - NexImage uses a 1/4" format
color CCD chip that gives the same approximate
magnification as a 5mm 50 degree field of view
eyepiece.
Camera control software:
Full camera control – allows you to
manually change the gain, contrast, exposure time,
frame rate and color saturation.
Preview mode – shows a live feed of
your image making focusing as easy as focusing an
eyepiece.
Video recording – capture streaming
video of solar system object used to generate the
final high quality image.
Image processing software:
Frame Lists – automatically allows
you to view individual frames of your video stream.
Quality cutoff filter – filter out
low quality images based on individual frame quality
and alignment differences.
Wavelet Filter – separates image into
a series of unsharp mask layer that can be
individually controlled to bring out all the hidden
detail of the image.
Image Processing Control – maximize
your image with the most powerful image processing
controls like, contrast, brightness, gamma curve, RGB
histogram and many more.
NexImage comes with the following:
How the NexImage works:
NexImage is a
complete solar system imager that is compatible with
most any telescope and gives users all the light
sensitivity and color fidelity needed for the highest
quality planetary images that only a true CCD chip can
provide.
NexImage utilizes a
CCD imaging chip to capture streaming video of any
solar system object. This video can easily be viewed
as hundreds of individual images (frames) that can be
digitally stacked to significantly reduce the electric
“noise” inherent in video chips and bring out the
unseen fine detail (signal) hidden with in your image.
The NexImage camera
takes advantage of the fact that the signal to noise
ratio of your stacked composite image is proportional
to the square root of the number of frames combined.
This means that stacking as few as 16 frames will
reduce the grainy noise of the composite image by 4
times. While stacking as many 1600 frames will improve
the image by 40 times! However, stacking the
individual frames is only half the power of the
NexImage imager.
With the included
software package, each individual frame is analyzed
for quality to filter out those frames most affected
(blurred) by poor atmospheric “seeing”. This form of
after-the-fact adaptive optics, leaves only the
sharpest, clearest frames to be stacked and aligned
into a high quality image.
Finally, powerful
processing features automatically break the image up
into individual unsharp mask layers that can be used
to bring out tremendous detail and reveal final images
that will rival those taken with astronomical CCD
cameras costing thousands of dollars.
