Processing Tips & Tricks

When during processing new tools or techniques are used, this is explained in the ‘Processing’ section of the image details page. But remembering what was applied for what image is not so easy. So below is a listing of such Tips & Tricks, with reference to the image where the technique was described.

Correcting imperfections and artefacts

• Remove background imperfections using Synthetic Flats (link)

• Rescuing stacking artefacts (link)

• Rescuing stacking artefacts 2 (link)

• Remove collar blips and aberrations from OSC images (link)

• Remove Magenta halo around stars (link)

• Removing ‘Diffraction donuts’ using an Adam Block technique (link)

• Correction for atmospheric dispersion in OSC image (link)

• Correcting StarXTerminator (SXT) errors (link)

• Remove Single pixel noise (link)

• Comparison Pixel Rejection algorithms (link)

Image Processing

• Noise-reduction without NoiseXTerminator; the MMT method (link)

• Noise-reduction without NoiseXTerminator; the MureDenoise method (link)

• Remove chromatic noise using Convolution (link)

• High Dynamic Range options (link)

• Old data processed with new tools (link)

• Prevent galaxy cores to blow out (link)

• Enhancing the blues (link)

• Finding the right Colour Balance (link)

• Using the iHDR script from Uri Darom (link)
