 NexImage Features
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:
- NexImage Camera with 1.25” adapter and USB cable attached
- CD-ROM including:
- Image capture software – to capture streaming video of image
- Image processing software – to align and stack individual frame into one high quality image.
- Quick Setup and Tutorial – complete with sample images
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.
