This proposal is submitted to continue the tradition of producing an impressive press release image for Hubble’s anniversary, the next one being in April 2018. It is primarily intended for outreach purposes. The goals of this proposal were discussed and tentatively approved at a meeting with Ken Sembach and the rest of the Leadership Team on 20 Dec 2017.

In further response to the CS review by Sylvia Baggett, I switched from F105W to F125W to completely avoid He 1.1 micron contamination. I also added FLASH=10 to the narrowband ACS parallel exposures. I tried to add a small dither offset to the IR mosaic, to improve the dithering of the ACS parallels, but APT didn't like it (broke the alignment or something) so I dropped it, since it is not essential. -- Max

I added FLASH to the narrowband filters but not the mediumband filter.
Optical and infrared imaging of the Lagoon Nebula (M8)
We propose mosaic imaging of the Lagoon Nebula, a large H II region also known as Messier 8 (M8) and NGC 6523, with WFC3 optical and infrared filters. We will also image a parallel field with ACS.
These UVIS and IR mosaics are designed to execute in Feb 2018 at the same orientation. Most of the exposure time is dedicated to narrowband filters, but we also obtain short broadband exposures for continuum subtraction and star colors.
