Celestron NexImage Solar System Imager

Celestron NexImage Solar System Imager Review

Celestron NexImage Solar System Imager Feature

  • Complete CCD solar system imager produces high-quality planetary images
  • View and capture live video on your computer screen
  • Software automatically filters out fuzzy frames for sharper image
  • Easy to install and use
  • Manually control gain, contrast, exposure time, and much more from your PC
Amazon.com Review Celestron's NexImage combines a sensitive CCD imaging device with powerful image processing software in one affordable package. Now anyone with a telescope can take pictures that are simply amazing.

Image of Jupiter taken with NexImage system
An image of Jupiter taken with the Celestron NexImage Solar System Imager

Amateur astronomers have been taking great pictures of the moon and planets by using modified Webcams. The favored Webcams for astro-imaging have been the hard-to-find Philips ToUCam and Vesta models because of their high-performance CCD chips. Now Celestron's Neximage puts the same CCD technology in a package that's ready to use with any telescope that accepts 1.25-inch eyepieces. The NexImage includes an anodized metal nosepiece that fits in a 1.25-inch eyepiece holder. When I installed the Windows based software, I also updated my Windows Media Player files. Then I simply plugged the NexImage into my computers' USB port, and I was ready to start taking pictures.

The NexImage CCD is sensitive enough that I can take "snapshots" of the Moon or Sunspots (always use a safe Solar filter, of course!) even without a motor-driven telescope. The real power of the NexImage package, however, comes from its included Registax software which automatically aligns and stacks hundreds of individual AVI video frames into one sharp, highly detailed picture.

I used my 8-inch Celestron Schmidt-Cassegrain telescope (similar to the Nexstar 8 GPS ) and my 2x Ultima Barlow lens to capture some beautiful pictures of Jupiter and Saturn. The sensitive Sony CCD chip in the NexImage easily shows color and detail on Jupiter that just doesn't show up when I use CMOS-based Webcams.

The fine performance of the NexImage package is limited somewhat by its included video capture software. The AmCap software doesn't give me the precise control of exposure times I'd like; I wasn't able to photograph the moon Callisto next to Jupiter, for instance, without overexposing the planet. Celestron doesn't mention the other little drawback in its ads. You'll have so much fun that your hard drive will start filling up with pictures and AVIs! --Jeff Phillips

Pros:

  • Sensitive CCD chip
  • Fits any telescope that takes 1.25-inch eyepieces
  • Powerful image processing software
Cons:
  • Takes practice to get the exposure time just right
  • Software is Windows only
  • You'll fill up your hard drive with pictures
The Celestron® NexImage astronomy is a complete CCD solar system imager capable of producing high quality planetary images with greater light sensitivity and color fidelity. The 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.

Celestron NexStar 4 GT Compatible Flexible Dew Shield

Celestron NexStar 4 GT Compatible Flexible Dew Shield Review


See more picture


Celestron NexStar 4 GT Compatible Flexible Dew Shield Feature

  • 100% compatible with Celestron Dew Shields.
  • Flexible dew shields are made of non-reflective, flexible, light weight foam rubber sheeting.
  • dew shields will not crack or dent like rigid (metal or hard plastic) dew shields.
  • Flexible dew shields can be stored easily rolled up, lay flat or stay on the telescope.
  • Flexible dew shields work better than rigid dew shield because foam rubber insulates better.
Dew Shields (dew caps) trap stagnated air in the front of the telescope. The temperature of the stagnated air is slightly higher and is enough to prevent dew from forming. Dew shields can be use as a shade to block stray light from entering the telescope or during daylight torrential viewing. Stay light lowers image contrast. ATOZstars Flexible dew shields are made of black close-cell light weight foam rubber sheeting, which is non-reflective and a good insulation material. The foam rubber sheeting forms the cylindrical shape with Velcro. The dew shield rubber sheeting is slightly elastic which allows a snug fit on the telescope tube. The dew shield can slide forward as dew shield or slide back onto the telescope tube on most telescopes to protect the telescope from accidental scratching of the telescope tube. The flexible dew shield can be store away easily by roll up tight, lay flat or stays on the telescope. Rigid dew shields are difficult to store especially large ones.

Sky-Watcher 8" DOB - Join the Ranks of Serious Observers ...Corresponding to the escalating "aperture fever" that has gripped amateur astronomy for several decades, an 8" diameter is now generally regarded as the minimum entry-level aperture for serious observing.The low cost, large diameter, and fast focal ratio of the 8" Sky-Watcher Dobsonian make it an ideal dedicated telescope for wide-field, deep-space observation of faint galaxies, nebulae, and star clusters.The low-power dramatically captures wide swaths of sky in a single view. Galaxies and nebula appear to pop out of the heavens as bright, expansive masses of stars, gas, and dust.Observing with the 8" Sky-Watcher DobsonianIf you have never before observed through a high-quality, wide-field Dobsonian, like the SW 8" DOB, you are in for one of the sweetest experiences in amateur astronomy. Imagine the exhilaration of opening a clam and discovering a pearl.The sky is full of pearls, astronomical pearls. While they won't make you rich in the financial sense, for amateur astronomers at least, observing the fabled pearls of deep-space is a rich and even exhilarating pastime. A catharsis for the soul that renders the mundane insignificant, and reconnects us with the inner child who revels in awe and wonderment.A night observing with the SW 8" Dob can leave you with a lingering sense of contentment long after the evening's viewing is over.

Celestron EdgeHD 925 CGE Pro Schmidt-Cassegrain Telescope

Celestron EdgeHD 925 CGE Pro Schmidt-Cassegrain Telescope Review


See more picture


Celestron EdgeHD 925 CGE Pro Schmidt-Cassegrain Telescope Feature

  • This Celestron 9.25" aperture aplanatic Schmidt-Cassegrain telescope produces astrograph-quality flat focal plane
  • Celestron's EdgeHD coma-free optics and a built-in field flattener ensures sharp focus all the way to the edge of the telescope field of view
  • Flexible tension clutches hold the mirror in place and reduce image shift when rotating the telescope tube around the CGE Pro equatorial mount
  • Cooling vents located on the telescope rear cell allow hot air to be released from behind the primary mirror
  • All EdgeHD telescope optical tubes are Fastar compatible for imaging down to f/2 with optional accessories
Celestron's innovative new EdgeHD telescopes are aplanatic Schmidt Cassegrain models designed to produce aberration-free images across a wide visual and photographic field of view. Celestron EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt Cassegrain telescope. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Superior edge performance not only creates rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron's High Definition optics you will be able to capture the faintest of galaxies all the way to the corner of your full frame camera chip. Coupled with Celestron's XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. The EdgeHD tube has been redesigned with top-notch features to make sure you get the most from your optics each and every night. Mirror locks hold the mirror in place and reduce image shift when rotating the tube around the mount. Flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror, keeping the image centered in the eyepiece (or chip). Cooling tube vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 60 micron mesh filter guaranteed to let warm air out without letting dust in.
