NGC 1499 (North Up, East Left)
NGC 1499, also known as the "California Nebula", is an emission nebula in the constellation of Perseus that lies at a distance of ~1,000 light-years. Its fluorescence is due to excitation of the Hß line in the nebula by the nearby O7 star, Xi Persei (also known as Menkib) which shines at magnitude 4. This image shows only the brightest portion of the nebula. It comprises 6 x Ha, OIII and SII (300 seconds each), 0.5m f/2.9 ASA Astrograph with FLI ML3200 camera at an altitude of 80 degrees on 11 October 2018. It follows the CFHT convention (Ha-OIII-SII mapped to RGB). The field of view is 34' x 23'.
