TL;DR: In this article, the optimal wavelength for detecting high-redshift distant galaxies is the 3 micron window in the zodiacal light, where the sky at 1 micron is very dark above the OH nightglow.
Abstract: Observations using space telescopes should be optimized for conditions that prevail in space. Since the sky at 1 micron is very dark above the OH nightglow, and because distant galaxies are brightest at wavelength greater than 1 micron, the Hubble space telescope should be very good at detecting and measuring faint, distant galaxies in the R and I bands. For later-generation space telescopes the optimal wavelength for detecting high-redshift faint galaxies is the 3 micron window in the zodiacal light. Observations of faint galaxies in the 1-3 micron region will be less affected by evolution than optical observations, leading to a better determination of q0.
