NGC 1499 California Nebula

NGC 1499 California Nebula

NGC1499 - Mar. 2021
Televue 127is - AIS6200MM - NB(HSO)/RGB filters
The NGC1499 Nebula is a large, but faint collection of gases in Perseus. It gets its name from its resemblence to the shape of California, with LA somewhere near its brightest point. It is generally too faint to see visually. To enhance its appearance, this image was taken with narrow-band filters, which focus on the spectra of certain elements, particularly, in this case, Hydrogen. Since hydrogren (alpha) appears red, its presence was assigned to the red colour in this image making the California Nebula appear bright red. Hydrogen is also the element from which stars are created, and this nebula, in the next outer arm of the Milky way (about 1000 light years from here) is rich in both hydrogen and new stars.
The Nebula is re-emitting light energy thought to provided by the star ksi-Perseus (aka Menkib), which is the bright blue star located just below and to the right of the Nebula (appropriately located at Las Vegas, Nevada?).
One drawback to narrow-band images is that they tend to distort the colours of stars. In this image, I used an image taken using regular red, green, and blue broad spectrum filters to re-colour the stars to appear more natural. Is it worth it - taking two sets of images? I think the answer is "only sometimes".
