... The edge of the higher-resolution VTSS H-alpha coverage in marked in red ; H-alpha structure larger than ~ 1 o has been removed to highlight narrow filaments. ...
... widths obtained both from optical H-alpha rotation curves and from global HI line ... within the Sloan Survey area for which we already have H-alpha rotation curves ...

... the emission lines in M42 were bright enough enough to show up in the passband wings of the H-alpha and O[III] filters ... from different filters than mine: red is Nitrogen [II] at 6583 , green is H-alpha at 6563 , and blue is O [III] at 5007 ...
... the GB6 survey and the VTSS+WHAM H-alpha emission ( Finkbeiner 2003, ApJS, 146, 407 ... in U are reproduced in high-resolution (arcminute) VTSS H-alpha emission maps ... Combined analysis of H-alpha intensity (dependent on the ne and Te) and of ...
... The red color, though artificial, should approximate the 6575 wavelength of the filter and of the H-alpha light from the nebula ... I also have a composite image below which adds blue colors from a broadband filter to the red from H-alpha. ...

... The SMUDGES Survey will cover 134 square degrees of imaging in in BVI, plus optical spectroscopy of about 13,000 galaxies and H-alpha imaging for thousands of galaxies. ...
... These structures are best observed at somewhat high latitudes so that they can be compared with other datasets, such as IRAS and H-alpha, without contamination by unrelated gas along the line of sight. ...
