Mosaics of the Carina Nebula ("CARINA")

In early February 2010, mosaic images of the Herbig-Haro 901 and 902 (hereafter just HH 901) star formation sites were obtained using both the visible (UVIS) and infrared (IR) channels of the new Wide Field camera 3 (WFC3). The new WFC3 observations include four pointings in a 2x2 mosaic pattern, with small dithers within each pointing to fill the gaps between the two CCD chips, and allow for the rejection of cosmic rays and detector artifacts. A mosaic image was also obtained for a parallel field, using the Advanced Camera for Surveys. In 2005, a 43-orbit investment of Hubble observing time was awarded (HST proposals 10241 and 10475), to study the Carina Nebula in the light of Hydrogen-alpha. Although these observations cover only a small central part of the entire nebula, it resulted in one of the largest contiguous ACS images ever collected. Most of the observations are part of a large mosaic, centered on the star clusters Trumpler 14 and Trumpler 16. Many smaller nearby fields were also imaged, including the spectacular Herbig-Haro object HH666 and the nearby NGC 3324. In 2008, the Hubble Heritage Team also obtained WFPC2 mosaic data for NGC 3324 (HST proposal 11800) with the [O III] and [S II] filters (F502N and F673N).
