Setting Up A New System

- Meade-Telescope
  Daytime
    align viewfinder
    train drive
  Nighttime
    basic alignment
    SMT
    PEC
  measure f-ratio (by way of pixel-scale) on test field without prizm (Jo uses M7)
   pc = (180*3600/PI) * ps / (f_ratio * D)
  pixscale = (0.206265*pixsize) / (0.254*f_ratio)  = 0.812067*pixsize/f_ratio 
  f_ratio  = (0.206265*pixsize) / (0.254*pixscale) = 0.812067*pixsize/pixscale
   pixsize [um], pixscale [arcsec/pix]

- DIMM
  pa-offset

how-to change prizm
 - align (ST5,ST7)
 - focus
 - measure separation in pixels
 - convert to arcsec -> telesocpe.ini
