Finally was able to capture the S2 data to complete the SHO data. A very clear night but the moon was full.
Wasn't sure if the S2 would add anything, but, things turned out nicely. Overall the S2 data adds additional "fullness" to the image bringing out additional details on the interior of the NA nebula.
IMAGE DETAILS
WO Star71 telescope, iOptron CEM40 mount, ASI1600MM camera (-15C), Chroma 3 nm S2/
Ha/O3 filters, StarShoot Autoguider
Acquisition with
APT, Guiding with PHD2, Processing with PixInsight
Lights: 21 x 10 min S2, 28 x 10 min
Ha, 9 x 10 min O3 (Total Exposure time = 9
hr 40 min)
Used the conventional SHO processing to create the SHO image. Increased detail by using a sharpened version of the
Ha data as the Luminance for the LRGB process (hence the acronym HaRGB rather than LRGB). Removed Magenta from just the stars while leaving it in the remainder of the image. I pushed the Color Saturation a bit just to "spice up" the image. I know this isn't to everyone's liking.
I tried two versions, one where I left the Green in the final version (first image below then removed the Green with SCNR to create the second version. I prefer the first one, but, know that Green is usually removed from our images.
Version without SCNR
Version using SCNR
Thanks for viewing.
