NGC1499_BiColour_16_12_22_V2

**Version 2, increased detail and contrast**

 

Well I know some of our friends across the pond wouldn’t think so but it was bloody cold that night at -7°C. Thankfully there was not any problems to talk about so most of my time was spent indoors, one of the reasons why Astro photography rules.

This is the second time I’ve imaged NGC 1499 in just over a year and it’s not a lot different to my original image except this was taken with the Explore Scientific 102mm F7 APO Carbon giving me an increased field of view of just over 2°.

 

Note:

I removed all the stars after the initial processing using StarNet++ and then added the Ha Combined with the Oiii stars back in at the end.

 

NGC 1499 also commonly known as the “California Nebula” is an emission nebula located in the constellation Perseus. It’s almost 2.5 deg in length and is approximately 1000 Light Years from earth with an apparent magnitude of about 6.
