Catalog Setup: (I used USNO-A2.0, but you should set it to your catalog, such as GSC...)

Use stars from magnitude: -2.00 to 13

In order to use the "FITS scale" and "FITS center", you need to do the following:
- File > Settings > Site and Optics:
   - Main Telescope:
       - Focal length: [set it to your scopes focal length, including barlows or reducers. My TEC140 f/7.0 says 980mm, but because plate solves always show 985, I've changed it to that.  It has to do with all the stuff in my optical train]
       - Aperture: [set it to the diameter of your scope's primary objective lens or mirror. Mine is 140mm. A 10" f/10 SCT would be 254mm aperture and 2540mm focal length.]
- Observatory Control window > Setup tab > Telescope > Connect: [connect to your scope either directly or through an ASCOM hub.  I use Generic Hub > ACP hub > APV2 driver for my AP1200 mount]

When it is set up this way in Maxim, the FITS scale is stored in Maxim and the image center RA/DEC is also stored in maxim.
