A quantitative assessment is presented of diraction-limited stellar images with Strehl ratios of 0.25{0.30 obtained by selection of short-exposure CCD images of stars brighter than +6 m at 810 nm with the Nordic Optical Telescope.

Diffraction-limited CCD imaging with faint reference stars
By selecting short exposure images taken using a CCD with negligible readout noise we obtained essentially diffraction-limited 810 nm images of faint objects using nearby reference stars brighterExpand
“Lucky Imaging” with Adaptive Optics
We present a new hybrid image-sharpening approach, which combines adaptive optics and frame selection. Observations were carried out with the 3-m Shane telescope. The method is shown to perform bestExpand
Lucky Exposures:: Diffraction Limited Astronomical Imaging through the Atmosphere
Through selection of short exposure images we achieve diffraction-limited I-band imaging from well-figured ground-based telescopes as large as 2.5 m diameter. The faint limiting magnitude and largeExpand
GravityCam: higher resolution visible wide-field imaging
A new concept of ground-based imaging instrument called GravityCam capable of delivering significantly sharper images from the ground than is normally possible without adaptive optics, which will improve substantially the quality of weak shear studies of dark matter distribution in distant clusters of galaxies and provide a vast dataset for asteroseismology studies.

Diffraction-limited I band imaging with faint reference stars
The use of faint reference stars for the selection of good short exposure images has recently been demonstrated as a technique which can provide essentially diffraction-limited I band imaging fromExpand
GravityCam : higher resolution visible wide-field imaging Conference or Workshop Item
The limits to the angular resolution has, during the latest 70 years, been obtainable from the ground only through extremely expensive adaptive optics facilities at large telescopes, and coveringExpand
High-speed, photon-counting CCD cameras for astronomy
The design of electron multiplying CCD cameras require a very different approach from that appropriate for slow scan CCD operation. This paper describes the main problems in using electronExpand
Noise free detectors in the visible and infrared: implications for the design of next-generation AO systems and large telescopes
This paper is intended to discuss the impact of noiseless CCD detectors in three significant areas of the development of large telescopes and the instruments that go on them. These are (1) CCDs thatExpand
AstraLux - the Calar Alto 2.2-m telescope Lucky Imaging Camera
AstraLux is a Lucky Imaging camera for the Calar Alto 2.2-m telescope, based on an electron-multiplying high speed CCD. By selecting only the best 1-10% of several thousand short exposure frames,Expand

The JOSE atmospheric seeing monitor at the William Herschel Telescope
We have installed a Shack-Hartmann wavefront sensor at the William Herschel Telescope. The sensor has 8 x 8 subapertures and operates at frame rates up to 865 Hz. It is used to monitor those aspectsExpand
Ground-based High-Resolution Imaging of Mercury
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 SunExpand
Measurements of Binary Stars with the Starfire Optical Range Adaptive Optics Systems
To investigate the relative photometry produced by adaptive optics within the isoplanatic patch, we observed four binaries, 10 UMa, UMa, 81 Cnc, and κ UMa, with adaptive optics using natural guideExpand
First light for Hokupa'a: 36-element curvature AO system at UH
The University of Hawaii adaptive optics program has scaled its previously successful 13 elements AO system to 36 actuators and named it 'Hokupa'a', meaning 'immovable star' in Hawaiian. First lightExpand
Probability of getting a lucky short-exposure image through turbulence*
In short-exposure imaging through turbulence, there is some probability that the image will be nearly diffraction limited because the instantaneous wave-front distortion over the aperture wasExpand
Subelectron read noise at MHz pixel rates
The conclusion is that these new deices have radically changed the balance in the perpetual trade-off between read out noise and the speed of readout and will force a re- evaluation of camera technologies and imaging strategies to enable the maximum benefit to be gained form these high- speed, essentially noiseless readout devices.

Hipparcos and Tycho Catalogues
This chapter describes various aspects of the Hipparcos and Tycho Catalogues useful for understanding the scientific exploitation considered in subsequent chapters. It describes some of the satelliteExpand
