This can be synthesised very easily with stellarium.
Use the ocular plugin.
Set the telescope and eyepiece paramaters to suit your scope and eyepiece. (don't forget the X,Y settings if the image is on a newtonian.
To give calibration rings use the equatorial grid display.
Centre the display on the SCP .
Select the SCP and then ocular.
The display will show a view window of what the SCP will look like with that particular telescope set up.
If there are too many stars go to the main menu (F4) and reduce the absolute magnitude so only the brighter stars show.
By the way, the meade telescope at park will not park on the SCP. They will park at AZM 0 and Alt 0
The sample views are for an 80mm refractor, 500mm Focal length and 26mm plossl eyepiece (52deg FOV)

This particular configuration has a FOV of almost 3 degrees
Note that Sigma Octans is visible in the lower right. Time about 4
