gcardona, were you able to find workaround for this?
I have the same request. I have QHY695A camera and I also need to leave overscan area in my frames to calibrate bias drift. I need to be able to specify actual center of useful image area on my frame so I will not loose signal when I do meridian flips. basically exactly same reason as described above by gcardona.
please add this feature - it would help to have an option in framing & mosaic wizard to specify center of the frame, which then should be used to center scope on the object.
to illustrate problem, this is how my frame looks like:
black area is overscan area, green area is useful signal area
then after meridian flip and stacking/aligning images - I end up with something like this
parts of data on the edges is unusable because it exists only on certain set of frames.
my full frame with overscan area is 3072x2240 , actual image is 2752x2160
so after I align and stack I loose 320px horizontally and 80px vertically.
so instead of my full camera resolution of 2752x2160; after I align and stack I end up with images of around 2400x2080. it would be really great to get a fix for that
i believe this is relatively easy to implement, one way I can think of
- add optional parameters to define effective imaging area coordinates relative to full frame in the form : top x left, bottom x right. think this should be on camera tab of equipment profile/sequence control panel.
- then with simple math it should be possible to determine actual center of effective imaging area in relation to full frame and use that point to center image
- then it would be nice if when you define your frame in “framing and mosaic wizard” the rectangles would represent effective imaging area of sensor if thats defined on camera tab, or just entire sensor size if effective imaging area settings left blank.
also this is not some kind of device specific request - I believe many cameras have overscan regions and quite many of them experience bias drift, so I believe this will be valued addition to SGP
