Oculus handbook Issue 2 January 2013

If this is an initial setting up session, set the ‘Autosave’ to off and select ‘Continuous’ mode. The

exposure time for a dark sky can be 20 seconds, or more, but for initial alignment and testing, set 5

seconds and press ‘Take Photo(s)’. You should see a sequence of images on the display and you can

experiment with the Oculus orientation and location to get the best views. The focus should be good, as

supplied, but if necessary it may be adjusted by unscrewing the large outer ring and lifting off the

dome. Loosen the small lock screw on the lens and gently rotate the top lens ring to refine the focus.

Re-lock the lens when satisfactory and replace the dome.

You can greatly improve the image brightness and contrast by setting up the ‘Max palette stretch’

option in the ‘View’ menu. I recommend using the ‘Linear’ stretch and adjusting the black and white

levels for the best view.
