What are the chances to have 3 concentric circles drawn around the cursor position. If the circles were at 0.5, 2 and 4 degrees, it would help to see what you might see through a Telrad spotting scope. Also if an object was selected and the space bar pressed, have the circles use the locked position as their center.
You seem to have CSS turned off.

I have often thought about something like that because it is annoying not to see the oculars FOV. Circles around the cursor are not easily possible, perhaps around the selected object, or, even better,
around the telescope marker.
Missing field of view circles, are the only reason, I have to use Sky Chart
instead of Stellarium.
Telrad circles in Stellarium 0.11.2 - http://astro.uni-
altai.ru/~aw/stellarium/stellarium-telrad.png - why many argue that they
are not exist?
Yes, the Oculars plug-in can display a Telrad reticle in the center of the
screen. If you enable the control panel GUI from the Oculars configuration
window, you can have a button for toggling it.
Another option is to use the Telescope Control plug-in to simulate a telescope
and set FOV circles around the reticle.
I worked that one out...
I literally measured the diameter of the telescope view on my monitor.
Then created a graticule.png in paintshop.
Printed it onto a transparency.
Laminated it to keep it safe.
Cut it to sit exactly over the telescope view.
Just resize this to fit your needs:- www.squeaky.org.uk/temp.graticule.png
