Applications Note
CCDOPS Version 3.6
March 4, 1997
This Application Notes describes the changes made to CCDOPS since version
3.5
Additions made to CCDOPS
* Added support for the VESA 1280x1024 by 256 color mode for photo mode.
* In guiding commands the software now forces the centroid of the guide star
to the center of the pixel for maximum S/N
* The adaptive dark subtract routine now makes sure there is enough image
statistics for the adaptive algorithm. Otherwise default coefficient
of 1 is used.
* Added a Spot focus mode to the ST-7, ST-8 and PixCel255 that follows
the brightest spot in the image around. It takes a full frame image in
the low res mode to find the bright spot and then tracks that spot around.
If you want to reacquire the bright spot within Focus mode reenter the
Spot mode by hitting the 'B' key or with the pull-down menu.
* Added a large version of the peak readout to the lower-left corner of
the Focus mode that makes reading this from across the room easier.
* Increased the maximum size of a HP laser printed image to 8 inches.
In the older software ST-7 images would print at 2.5 inch width and
now they print at 7.5 inch width.
* Added a Turbo update mode to the Focus command for the ST-7 and ST-8
that allows shorter image times and faster throughput by just leaving
the shutter open. You will notice steaking of bright objects with short
exposures when using this mode since these CCDs are not frame transfer
CCDS.
* Reduced the size of the tracking image in the ST-7/8 to exclude hot
pixels that showed up at the bottom of some units making the
Tracking Calibrate routine require brighter stars.
* Allow up to 9999 images in auto grab.
* An Auto Bias feature has been applied to ST-7/8 Imaging CCD images
such that short dark images will now show around 100 counts.
Also, the Display Parameters dialog has been updated to show whether
Auto Bias Level was used to capture ST-7/8 images by the addition
of the ABL field in the Readout State data.
* We added an option titled "Non-ABG Streak Removal" to the ST-7/8
Camera Setup Command. Users of non-ABG protected versions of these
cameras should enable this option to prevent horizontal streaking of
bloomed stars. This is only active in the Medium and Low Resolution
modes where the on-chip binning causes this effect. This slows down
the readout in these binned modes but removes the unsightly effect.
Note that this is applied in the Focus mode so as to not slow down
focusing unless you have enabled the Auto Grab mode of the Focus command.
Users with ABG protecte versions of these cameras should leave this
option disabled.
* We removed the artifical saturation limit of 16,384 counts when the
ST-7/8 were used in the high resolution mode. Now rather than limiting
the A/D at 16K we let the CCD's saturation limit the readout. This allows
users of the non-ABG versions of these cameras to realize the higher
full-well capacity of those cameras.
Bug Fixes made to CCDOPS
* Fixed a bug in the PARDRV driver that could cause ST-7/8 cameras
to have a slight horizontal streaking in low level light frames on
fast computers
* Fixed a bug that could cause Auto-dark subtracted images
to be corrupted when running under Windows and when
extended memory was low
* Fixed a memory leak that caused the software to hang on exiting to DOS
when used with an ST-7/8 and the active CCD was changed.
* Fixed a bug in the Dark Subtract command in the Utility menu that would
clip ST-7/ST-8 high-res pixels to 16383 counts.
* Fixed a bug in the VESA driver that caused the mouse cursor to show
stripes on some VESA displays and to move in increments of
4 pixels.
* Fixed a bug in the VESA driver that would leave images of the selection
box behind as it was moved on some VESA displays.
* Fixed a bug where taking an image thru midnight would report much time
left in the exposure.
* Fixed a bug in the Zoom 4X and Replicate commands where images that
had been previously Enlarged and then Zoomed would get corrupted.
* Fixed a bug that when a Color Grab sequence was taken with the Track
and Accumulate command the filter wheel would always try to use the
Blue filter on subsequent images.
