Settings in Nebulosity 4 for colour images using QHY10 single shot colour camera

Taken me a while to come up with some settings that work – following appears to do so.

From FITS liberator on a FITS file taken with this camera, a test image had following headers:

Image #1
SIMPLE = T / file does conform to FITS standard
BITPIX = 16 / number of bits per data pixel
NAXIS = 2 / number of data axes
NAXIS1 = 3896 / length of data axis 1
NAXIS2 = 2612 / length of data axis 2
EXTEND = T / FITS dataset may contain extensions
COMMENT FITS (Flexible Image Transport System) format is defined in ‘Astronomy
COMMENT and Astrophysics’, volume 376, page 359; bibcode: 2001A&A…376..359H
BZERO = 32768 / offset data range to that of unsigned short
BSCALE = 1 / default scaling factor
CREATOR = ‘Nebulosity v4.1’ / program and version that created this file
INSTRUME= ‘QHY10 ‘ / instrument name
DATE = ‘2019-08-06T17:46:56’ / UTC date that FITS file was created
DATE-OBS= ‘2019-08-06T17:46:25’ / YYYY-MM-DDThh:mm:ss observation start, UT
XPIXSZ = 6.05 / X pixel size microns
YPIXSZ = 6.05 / Y pixel size microns
CCD-TEMP= 8.380482 / CCD temp in C
EXPOSURE= 0.005 / Exposure time [s]
GAIN = 0 / Camera gain
OFFSET = 130 / Camera offset
BIN_MODE= 1 / Camera binning mode
ARRAY_TY= 1 / CCD array type
XOFFSET = 1 / Debayer x offset
YOFFSET = 1 / Debayer y offset
XBINNING= 1 / Camera binning mode
YBINNING= 1 / Camera binning mode
EXPTIME = 0.005 / Exposure time [s]
FILTER = ‘No filter’ / Optical filter name

 

Nebulosity 4 settings for QHY10 single-shot colour camera 6/8/2019:

Important aspects are that Acquisition mode was changed to “Recon (RGB/square: Quality” & Desmosaic (debayer) method to “Color binning” options.

The inbuilt QHY10 driver was used in Nebulosity 4 to obtain this image.

After changing these settings, I clicked on <auto colour balance> under <image> tab.
