Description

Rosette Nebula in narrowband taken 10 Feb. 4 hours of exposure in 600s images.

Lucky with no moon and quite clear skies but window of visibility also coincides with the street lights being on. For teh short about of data it seems to come out well. Not sure it's the final rendition of the data...

Pre-Processing:

WBPP for calibration

Batch format conversion of calibrated images with output with "compression-codec lz4hc+sh"

SubFrame Selection

Registration of all against best Ha Frame, output with "no-compression"

Integration of SHO channels with Automatic Normalisation

Linear Stage:

All S, H, O channels:

Dynamic crop of all to suit trim of combined data edges

ABE of each chn (Interpol function = 1, subtract, no normilization)

Ha data only:

EzDecon (Itt=59, Pixmath=10, defaults for rest of settings)

EzDenoise (defaults)
