Environmental Data

Date: June 13, 2026     Start Time: 10:43 PM    End Time: 2:39 AM    SQM: 17.0

Moon Age: 27.5 days     Moonrise: 2:42 AM     Moon Illumination: 4.6%

Temperature: 77.9 degrees F    Humidity: 54%    Dew Point: 59.9 degrees F

Location: Westport, Massachusetts 02790    Sky Condition: Clear

Comment: I started around 9:30PM however using Sequence Generator Pro I did not select 'Mechanical Angle' for rotator so I had to start over. I use Mechanical Angle since I am also capturing 'flats'.

Imaging Processing

Imaging Processing Software: PixInsight

Processes utilized: Linear - calibration/integration: For each of the LUM, RED, GREEN, and BLUE lights: Flats ImageCalibration with Master Bias, Flat ImageIntegration, Images ImageCalibration with Flat Master & Dark Master, SubFrameSelector
StarAlign all calibrated lights using best LUM image as reference, ImageIntegration of each of the LUM, RED, GREEN, BLUE sets

Linear - Background extraction, Color correction, deconvolution, noise reduction:
LUM DynamicCrop to trim, GraXpert, BlurXTerminator, NoiseXterminator
RED/GREEN/BLUE DynamicCrop to trim, GraXpert, ChannelCombine to create color image using only Red/Green/Blue, BlurXTerminator, NoiseXterminator, Image Solver script, SpectroPhotometricColorCalibration

Non-Linear: LUM: MultiscaleAdaptiveStretch
Color:MultiscaleAdaptiveStretch
ImageBlend script to combine LUM and COLOR masters, GAME script to create mask of galaxy, CurvesTransformation to increase color saturation, LocalHistogramEqualize, HDRmultiscaleTransform to increase dynamic range, DynamicCrop
