The great star forming region NGC 1333 in the Perseus Molecular Cloud

About this object

This image has a great story behind it. I recently posted an image of NGC 1333 taken from home with my 152mm refractor. A friend of mine and also a WM Keck Astronomer in Hawaii, wrote me that he liked the image and he had high resolution data of NGC 1333 taken with the 4 m Mayall reflector on Kitt Peak that had not been combined into a color image. The data was used in a research paper published in 2005 in the astronomical journal. The authors found 72 new HERBIG-HARO objects within a larger field and many within the field of this image. I've also included a link to an annotated image which shows the new HERBIG_HARO discoveries. The resolution of the image is 0.28 arcsec/pixel. Please check out the higher res image links above for incredible resolution of nebula details.

Processing: The image is a false color composite assigning SII and Ha to the Red channel, Ha and I band to the Green channel and I band to the Blue channel using pixelmath. A synthetic luminance image was created from the three masters and 40 iterations of deconvolution were run sharpening the luminance. This was combined with the color composite creating the image above. A starless mask was generated using the luminance image and Starnet ++. This mask was used to perform several iterations of local histogram equalization. Saturation was increased also using the starless mask. No noise reduction was performed on the image.
