NGC 1499, The California Nebula from a city

[Bluecloudyeagle]

This is my best image of this target yet, with 31+ hours shot on this target and the best 24 hours stacked to get this vibrant result! The much fainter Sii sulphur data provided the yellowish-orange colour as opposed to the traditional red associated with this target. It’s hard to believe such an image can be shot from a light polluted city, but it just shows the power of narrowband filters and long integration times. It took my 15 nights to shoot this target, the longest I’ve done by far. This is a 2 panel mosaic, which was needed to fit the large nebula at my FL of 360mm. With the help of NINA’s platesolving, the mosaic alignment and capture was a breeze.

That is remarkable from the Agra pollution conditions (both light & particulate matter)!👍🏾
