Images obtained during the 1974–1975 Mariner 10 flybys of Mercury revealed nearly 50% of the surface of the planet at very high spatial resolutions. Since then, Mercury's close proximity to the Sun has foiled nearly all ground-based and space-based attempts to achieve high-resolution images of the remainder of the planet. We have used a novel technique to obtain nearly diffraction-limited images of Mercury using the Mount Wilson Observatory 60 inch (1.5 m) reflecting telescope. These images are… 
Earth-Based Visible and Near-IR Imaging of Mercury
Abstract New planned orbiter missions to Mercury have prompted renewed efforts to investigate the surface of Mercury via ground-based remote sensing. While the highest resolution instrumentation
Resolved images of an unknown sector on the surface of Mercury
We took electronic photographs of Mercury on the side of the planet that was not photographed from the Mariner-10 spacecraft in 1973–1975 by the millisecond-exposure method in ground-based
Study of the unknown hemisphere of mercury by ground-based astronomical facilities
The short exposure method proved to be very productive in ground-based observations of Mercury. Telescopic observations with short exposures, together with computer codes for the processing of data
A Digital High-Definition Imaging System for Spectral Studies of Extended Planetary Atmospheres. I. Initial Results in White Light Showing Features on the Hemisphere of Mercury Unimaged by Mariner 10
We present an instrumentation plan for spectral imaging of Mercury's extended atmosphere. The approach depends upon simultaneous short-exposure images in white light and sodium, with the former used
Vast dark regions in the northern hemisphere of Mercury
Images of the 280°–360°/0°–10° W longitude sector of Mercury’s surface produced from the results of recent ground-based astronomical observations are presented. This sector remained beyond the
A Side of Mercury Not Seen by Mariner 10
More than 60,000 images of Mercury were taken at ∼29° elevation during two sunrises, at 820 nm, and through a 1.35 m diameter off-axis aperture on the Southern Astrophysical Research telescope. The


Science with the ADOPT system on Mt. Wilson
The cassegrain adaptive optics system (ADOPT) on the Mount Wilson 100-inch telescope has been in operation now since June of 1995. This report chronicles the ongoing performance improvements, the
Optical Resolution Through a Randomly Inhomogeneous Medium for Very Long and Very Short Exposures
A theoretical foundation is developed for relating the statistics of wave distortion to optical resolution. The average resolution of very-long- and very-short-exposure images is studied in terms of
The image quality obtainable with shift-and-add (SAA) imaging for the recovery of diffraction-limited information is quantitatively investigated using data simulating an 8-m aperture at a site with
UnISIS: a laser-guided adaptive optics system for the Mt. Wilson 2.5-m telescope
Final design details are given for UnISIS, the University of Illinois Seeing Improvement System. The principle components include a 50 Watt Excimer laser working at 351 nm which produces a pulsed
