Star factory, the Orion Nebula

    Newer Older

    M42 is a glorious mix of diffuse nebula and one of the the brightest nebulae in the sky. It's a wonderful target for novice to experienced imagers as there's always more data and detail to find. It's easy to capture - but difficult to master. This is my 5th go at imaging M42, it feels like l I'm coming full circle as this was the target that inspired me to purchase by current Officina Stellare APO.

    Previous attempts:

    www.flickr.com/photos/astro-tanja/8103642749/ (comparisons since my 1st ever imaging of the target)

    The choice of 2 exposure settings was to capture more feint outer detail with the longer exposure, and shorter exposures to maintain the inner core. After calibration the 2 masters were integrated using the HDRcomposition function in PixInsight. It's an easy method, making me wish I shot even more data for longer subs to get more detail in the surrounding feint nebulosity.

    This target was imaged from the Johannesburg light polluted suburbs, with no light pollution filter. I spent 2 nights on this to acquire more data so that I can keep ISO lower.

    Excited to see if next season will bring more improvements.

      I'm rarely surprised by a photo of Orion there days, but yours is extremely beautiful. You can see all the nebulosity and there's no discernible noise! Congrats!

      StormLV Thank you :) I took care to get a lot of light frames so noise wouldn't be so obvious. Thanks for the comment
