Image acquisition program for Quantum Scientific Imaging, Inc. 500/600-series CCD cameras.
Provides control of camera exposure parameters including filter selection (if camera is equipped with a filter wheel).
Provides graphical subframe selection.
Provides visual focusing capability augmented with FWHM (Full-Width, Half Maximum) and HFR (Half-Flux Radius) measurements.
An unlimited number of exposure requests can be submitted for automatic processing.
Image data can be saved in FITS (Flexible Image Transfer System) or TIFF formats.
What's New in Version 1.2
Note: As a result of sandboxing requirements this new version of QSEye no longer has a default location in which acquired image data is saved. You will be required to specify a save folder in order to enqueue processing requests.
Moved from a single window to separate windows for different settings/controls
Alerts & Temperature
"Alerts & Temperature" and "Imaging" windows
Any changes made (with the exception of the subframe settings in the "Imaging" window) are persisted and re-instantiated on subsequent camera connection.
The "Imaging" window subframe setting is always set to its full frame value which is then adjusted by the first filter binning settings which are persisted.
Settings are maintained per-camera based on model and serial number.
"Camera Connect" window will automatically miniaturize when a successful connection to a camera is established.
"Alerts & Temperature" window
Added tracing views for for CCD and heatsink temperatures as well as power consumption.
Added a fast readout option to the subframe selection; enabled based on camera support.
This option is independent of the same option in the "Exposures" window.
Added a set of exposure duration controls for subframing.
These controls are independent of those in the "Exposures" window.
Added a fast readout option; enabled based on camera support.
This option is independent of the same option in the "Imaging" window.
A new FITS keyword (QREADOUT) is used in images saved as FITS files representing the readout mode selected for the exposure.
Value is either QUALITY or SPEED.
Added a total exposure time field to let you know the amount of time required by the exposures you're adding.
Changed to utilize the maximum binning values the camera supports.
The area of the CCD to use is controlled by the subframe settings in the "Imaging" window.
Added elapsed and remaining time fields for the current exposure.
Added remaining time field for all exposures.
Added an estimated completion field as to date and time the exposures will finish.
In addition to displaying the FITS metadata keywords, QSEye will also display the image (if any) the FITS file contains. This is contingent on the metadata describing the image being consistent (particularly for a multi-HDU file having consistent image dimensions and pixel depth).
All windows displaying an image now incorporate black and white level adjustment sliders.
When the window is displayed (or re-displayed) the values of the sliders are continually updated from the image being displayed.
Once a manual adjustment to either slider is made any new images displayed in the window are displayed according to the set black and white levels.
On-line help has been updated per the above.
Good idea but it needs a lot of improvement
I was hoping to be able to run my QSI CCD with this app and my MacBook Air. The app does not give obvious feedback so it's difficult to know what it's doing. Being used to other sequencing software the frame and focus routing is clunky to say the least. If I understand it well, opening the frame and focus window automatically makes the camera start taking exposures. That is a really annoying feature. i would prefer to have separate buttons to take one shot or a series, as desired.
The app responds very slowly to commands and sometimes it hangs making me fear that something bad is going to happen to my 5,000 dollar camera.
I was also hoping for a more intuitive way to define filter sequences and rotation through filters. The app only lets select two types of binning. One for the first filter, the other for the rest of them. I would like to have the option of selecting binning type for each filter. It would be nice to have the ability to cleadly define a sequence as a list of events that are listed in a time sequence top to bottom and numbered. Seems like an obvious layout to me.
Furthermore the zoon feature in the image preview did not work for me. It's great that someone has started a mac app for QSI cameras and that it costs only 20 bucks, however it doesn't seem ready for prime time. I don't feel bad about buying this app as I hope that the funds will help further developing it, however - alas - for the time being I am forced to keep using some more complete windows based sequencing software.
In essence I would love to have a better organized, easier to utilize, user interface. I suggest looking ad Backyard EOS as en example of elegant design and good user interface.
