Calibrate images

See FocusMax Tutorials to setup image calibration


CCD Central Region

The CCD Central Region is used to limit the target star detection to a user defined central region on the CCD which reduces the influence of optical aberrations that may be present in the optical system. SCT and fast Newtonian users with large CCD chips may want to set this to 50% in order to minimize the influence of astigmatism, curvature of field, coma, etc. The default setting is 75%, if you have a large ship, then you setting this to 50% or smaller will reduce the download time and increase the speed the star detection routine. The CCD Central Region is drawn with a box on the CCD chip diagram found on the lower left corner of the FocusMax Focus window.


Flush Camera

This setting will initiate user defined number of exposure to flush the chip following the autofocus run to help prevent ghost image of the target star.


Image border

Specify the number of pixels to remove around the image border (default = 3) which may help with star detection with some systems.


Link delay

This setting will initiate a delay before the camera link is performed. This is useful if camera autoconnect is enabled were the imaging software is loaded then a connection is made to the camera.

Pre-exposure delay

Specifies the number of wait seconds before an image will be taken


Post exposure delay

Specifies the number of wait seconds after an image is taken.


Seeing Simulator

Specify variation the that will be used on calculating the HFD when operating FocusMax in Simulator mode. A setting of 0 will introduce no seeing variation, a setting of 5 is maximum variation, default = 3.
