Hey there,
to the forum! How did you find us?
You should see bright stars on the LCD display, but you won't see a lot.
Use a fast aperture (lowest f/number), high ISO (400+) and it might help see it on the LCD. When taking pictures, use a long shutter (15s to start with) until you have your barndoor tracking.
Good luck!
There's a few members who have made barndoor mounts, do a search and see some of their handywork!
