Enhanced Vision
What is Enhanced Vision ?
Enhanced Vision is a system that uses its low-light sensor to accumulate light
continuously through the live accumulation (stacking) of a series of short exposure
frames. Enhanced Vision improves the objects you see with time.
Depending on observing conditions (light pollution, moon phase, weather, etc.) and
the objects you are pointing at, it can take a few seconds to a few minutes to see their
colors and shapes using Enhanced Vision while using.
Software
The eVscope 2 software uses its on-board computer to stack and process frames (dark
and background removal, shift adding and stacking). It produces an improved image
and projects it in real time with a derivation algorithm that compensates for the earth
movement / rotation. This allows long exposures of objects the user is viewing.
Image Overlay
You can save images with or without an overlay by selecting your
preference in the Settings of the User tab. The overlay shows the
name of the object, coordinates, date and time.
Gain
What does the gain do ?
Gain electronically increases the signal in Live View mode. The lower the gain, the better
your images ; the higher the gain, the brighter the image. When you increase the gain,
you also increase the noise: you will see fainter objects, but they will be more noisy.
Exposure Time
What is exposure time ?
Exposure time is the length of time the sensor is exposed to light (between 1ms and 4s
for a single exposure in Enhanced Vision mode).
Magnifi cation
What does magnifi cation do ?
Magnifi cation is fi xed at 50x but can be increased it up to 8x. You can therefore zoom
up to 400x max.
How to change the magnifi cation ?
A double tap on your screen will zoom to 150x. You can adjust it by sliding two fi ngers
on your screen. Saving an image, in Live View or Enhanced Vision while the zoom is
applied will not save the zoomed image, it will save the original one.
The eVscope stacks images every 4 seconds
