With Gemini North coming on-line, US astronomers have an expanded range of imaging capability available through NOAO.

Articles in this issue describe new capabilities with three instruments in different areas of the resolution--field of view--wavelength domain. Counter-clockwise from upper right:

• 0.13" resolution with the Hokupa'a/ QUIRC adaptive optics camera at Gemini North.
• 7.3'-square field with the four-color IR camera SQIID at Kitt Peak.
• 0.8 x 1 degree field with the optical CCD camera Mosaic at Kitt Peak.
