Control
Description
V1
Vertical adjustment for the shorter wavelength image
V2
Vertical adjustment for the longer wavelength image
H2
Horizontal adjustment for the longer wavelength image
Split
Separates the two images horizontally.
Always turn ANTI-CLOCKWISE for optimal image separation
Component mounts
Drop-in positions used to insert a variety of different components into
the light path of either the shorter (reflected) wavelength or longer
(transmitted) wavelength image. These include:
•
Shutter plate: used to physically block one of the channels
when utilising ‘single-channel’ mode
•
Neutral density (ND) filter: useful when one image is dispropor-
tionately brighter than the other
•
Corrector lens: used to reduce chromatic aberration and en-
sure both pathways are focussed on the camera sensor
Trim
Corrects vignetting, which is characterised by one image appearing
darker towards one edge. See the ‘Image Optimisation’ section.
Longer (transmitted)
wavelength channel
Shorter (reflected)
wavelength channel
