Metrology of optical telescope components
Precision astronomic structures such as telescopes often require structural materials that possess ultra low coefficient of thermal expansion (CTE) and coefficient of moisture expansion (CME) so that strict dimensional stability requirements can be met. Composite materials such as carbon fiber …

Reinforcement learning for telescope optimisation
… the possible use of reinforcement learning for telescope target selection and scheduling in astronomy with the hope of effectively mimicking the choices made by professional astronomers. This is relevant as next-generation astronomy surveys will require near realtime decision making in response …

Gravitational Lensing and Telescope Aberrations
… and patterns imparted onto images by misaligned telescopes. As telescope aberrations will generally interfere with lensing measurements, it is important to be able to quantify and ultimately minimize them. The conclusions of this first part are (1) misaligned telescopes produce the same …

Robotic control of a photometric telescope
… of this project was to design and implement the telescope control software for the Alan Cousins Telescope (ACT), a robotic telescope at the Sutherland, South Africa, site of the South African Astronomical Observatory (SAAO). The approach adopted involved a high level of modularisation of the …

Queue scheduling the Alan Cousins Telescope
The Alan Cousins Telescope is a 0.75-m automatic photoelectric telescope situated at the South African Astronomical Observatory, in Sutherland. The telescope was designed and built to execute a range of photometry programmes, but is used mainly for the long-term monitoring of variable stars. In …

RFI monitoring for the MeerKAT Radio Telescope
… is currently building MeerKAT, a 64 dish radio telescope array, as a pre-cursor for the proposed Square Kilometre Array (SKA). Both telescopes will be located at a remote site in the Karoo with a low level of Radio Frequency Interference (RFI). It is important to maintain a low level of RFI to …

Imaging the sun with the Drao synthesis telescope
The Synthesis Telescope at the Dominion Radio Astrophysical Observatory in Penticton, British Columbia, has been modified to make full-disk continuum maps of the Sun at 1420 MHz. The hardware and software systems of the telescope were augmented for this purpose. The standard observing procedure was …

Optomechanical Design of a Space Telescope Primary Mirror
… is the most critical component of a space-borne telescope. The size of the primary mirror is the main driver for the resolution of the telescope. A high resolution telescope requires a larger primary mirror with the high-precision requirement of deformation due to space thermal loads, gravity …

Sparse Aperture Speckle Interferometry Telescope Active Optics Control System
<p>A conventional large aperture telescope required for binary star research is typically cost prohibitive. A prototype active optics system was created and fitted to a telescope frame using relatively low cost components. The active optics system was capable of tipping, tilting, and elevating the …

State Space Model of a Light Weight Flexible Telescope
The accuracy of optical telescope in the past was dominated by the construction of the telescope body and the precision of optical surface. This thesis fits into a larger project with a goal of controlling a flexible telescope in order to help a cheaper telescope achieve higher accuracy. In order …
