Eta Carina Nebula 2021 – BillD's corner of the net

Eta Carina Nebula with QHY 268 camera

The Carina Nebula or Eta Carinae Nebula is a large, complex area of bright and dark nebulosity in the constellation Carina, and is located in the Carina–Sagittarius Arm. The nebula is approximately 8,500 light-years from Earth and is 230 light years across.

This is image is from 1 hour of 2 minute exposures using the Esprit 120mm Refractor and the QHY 268c Colour camera.

I have imaged this nebula several times before, but I like trying it out whenever I get a new camera. In this case is is a one shot colour image.

Note that the stars lack the deep colours as I was using an extreme narrowband filter to defeat the bright city lights and the bright moon. The L-Extreme filter cancels out a lot of the starlight while capturing the Oxygen and Hydrogen in bright nebula. The colours come from processing the image using HOO (Hydrogen,Oxygen,Oxygen) which extracts colour using similar to those used for Hubble images.
