Technical aspects of the new AAO / UKST H interference lterQuentin
نویسنده
چکیده
We brieey describe technical aspects and speciications of the new UKST H interference lter which is probably the largest of its kind available in astronomy. Preliminary exposures show that the lter gives excellent imaging with high overall transmission and uniformity at H wavelengths. This is achieved over a circular area of about 305 mm diameter or about 5.7 degrees (the so called`clear aperture'). The prospects for the new UKST H survey of the Southern Milky Way with this new lter are excellent.

MASH-II: More Planetary Nebulae from the AAO/UKST Hα Survey
We present a supplement to the Macquarie/AAO/Strasbourg Hα planetary nebulae (PNe) catalogue (MASH), which we denote MASH-II. The supplement consists of over 300 true, likely and possible new Galactic PNe found after re-examination of the entire AAO/UKST Hα survey of the southern Galactic Plane in digital form. We have spectroscopically confirmed over 240 of these new candidates as bona-fide PN...
متن کاملFive WC9 stars discovered in the AAO/UKST Hα survey
We report the discovery of 5 massive Wolf-Rayet (WR) stars resulting from a programme of follow-up spectroscopy of candidate emission line stars in the AAO/UKST Southern Galactic Plane Hα survey. The 6195-6775 Å spectra of the stars are presented and discussed. A WC9 class is assigned to all 5 stars through comparison of their spectra with those of known latetype WC stars, bringing the known to...
متن کاملA New Wolf - Rayet Star and its Ring Nebula : PCG 11
In a search for new Galactic planetary nebulae from our systematic scans of the AngloAustralian Observatory/United Kingdom Schmidt Telescope (AAO/UKST) Hα survey of the Southern Galactic Plane, we have identified a Population I Wolf-Rayet star of type WN7h associated with an unusual ring nebula that has a fractured rim. We present imagery in Hα, the 843-MHz continuum from the Molonglo Observato...
متن کاملFilamentary shell structures from the AAO/UKST Ha survey
Here we present the first results of a search for new optical supernova remnant candidates and other filamentary objects on films produced by the Anglo-Australian Observatory/UK Schmidt Telescope Há Survey. Sixty-one fields, or 26% of the Galactic plane survey fields, have been visually examined. This has resulted in the detection of four newlarge diameter filamentary structures, and the discov...
متن کاملTTF: A Flexible Approach to Narrowband Imaging
The Taurus Tunable Filter (TTF) is a tunable narrowband interference filter covering wavelengths from 6300Å to the sensitivity drop-off of conventional CCDs (∼ 9600 Å), although a blue ‘arm’ (3700−6500Å) is to be added by the end of 1997. The TTF offers monochromatic imaging at the cassegrain foci of both the Anglo-Australian and William Herschel Telescopes, with an adjustable passband of betwe...
