Description

Hydrogen data from early 2020 with the original goal of capturing a SHO render, but Central American weather then the pandemic shut this project down and I haven't had the opportunity to return to complete it (so far!).

---Updated with color image revision

My preferred final image (so far!) remains the monochrome Ha one taken with the 350mm optic; I like the detail and the tonal range of this image. After searching my NAS server I located an earlier set of SHO data and used these to make the color revision in ForaxX palette with the mono 350mm image providing the detailed "luminance" channel.

The original trouble with this SHO data was that the Nikon zoom lens I used at that time proved a disappointing choice for astrophotography, producing poor quality stars especially toward the corners. But it's an acceptable source of color data in starless form. The SHO image did not cover the mono's entire FOV, hence the crop.

SHO data acquired Jan-2019:

2019-01-07 SQM 21.96 20C ambient
2019-01-08 SQM 22.01 19C

ASI1600MM Gain 139 -10C using Optolong 36mm NB Filters in a Starizona filter drawer.

Nikon Lens 70-200 mm AF-S VR-Nikkor 70-200mm 1:2.8G set to FL=200mm. The f/2.8 exposures were with the Nikon lens wide open. The f/3.6 were with a set of external filter-size adapter rings down to 55mm.

SII f/3.6 144x30sec Optolong 36mm filter 6.5nm

Ha f/2.8 108x30sec Optolong 36mm filter 7nm
      f/3.6 31x30sec f/3.6 18x60sec

OIII f/3.6 126x30sec Optolong 36mm filter 6.5nm
