Hubble Space Telescope (HST):

  • Hubble Space Telescope (HST):

  • HST NICMOS:

    • 189 x FoV,
    • 38 x better sensitivity at K band, 8 x at H band
  • Spitzer:

    • 8 x Spitzer diameter
    • Diffraction limited at 2 microns vs. 6 microns
    • 8 to 24 x better angular resolution
    • 10 x lower dark current supports R ~ 1000 at high redshift
  • Ground:

    • JWST and GSMT are complementary where capabilities overlap:
    • HST: Keck diameter ratio ~ JWST:GSMT
    • Background ~1,000,000 x larger on ground at 5 microns
