MOAO). • ELT pathfinder. • Needs to know the altitude of the dominant turbulent layer above the 4.2m William Herschel Telescope (WHT) in real time. • pt5m: SLOpe Detection And Ranging (SLODAR). • 0.5m robotic telescope on WHT roof, with Shack-Hartmann wavefront sensor; PI: Richard Wilson (Durham).
a priority. • Small, fast, high-quality telescope at an excellent site. • “Cheap” telescope time c.f. LT, so good for pointing at more marginal or brighter transients. • Good for multi-colour, long-term monitoring observations once a transient has been discovered.
Doi Inthanon (2,457m). • High quality telescope (EOS), with 5- port Nasmyth focus. • Dark site (in a national park) with excellent seeing (0.8”-0.9” median). • Mainly use in 7-month dry season (Nov- May). • Permanently mount ULTRASPEC on TNT in exchange for 30 nights per year.
Warwick/UKATC. • Used on EFOSC2 spectrograph on ESO3.6m and 3.5m NTT for 43 nights in 2007-2009. • Shares data acquisition system with ULTRACAM. • Uses a frame-transfer EMCCD, giving up to 100 Hz frame rates with zero readout noise.
”/pixel platescale. • 6-position wheel with u’g’r’i’z’ and clear filters. • MoU signed with Thailand in 2011. Commissioning Autumn 2012. • We would like to make follow-up of LOFAR transients a priority. • Good for deep, high-speed photometry of faint transients. • Not robotic, but manual overrides in our 30 night p.a. allocation (and DDT in the remaining time) possible.
