Dr. Elara Vance stared at the data stream, her reflection ghosting over the cascading numbers. For eighteen months, the telescope had been pointing at a patch of sky that looked empty—a stellar graveyard where light went to die. But the spectrograph told a different story. It whispered of something vast, ancient, and non-luminous.

Since the exact phrase "Linear Link" is ambiguous, this essay will explore the most logical interpretation: within PixInsight. This is a critical technique for maintaining color fidelity during the early stages of processing. pixinsight lerar link

STF applies the exact same transformation to the Red, Green, and Blue channels. If your raw data has a heavy green or orange cast (common with light pollution or Bayer filters), a linked stretch will show that cast prominently. But the spectrograph told a different story

Apply a slight Pedestal (e.g., +100 ADU) to both your reference and lights before LN. In WBPP, under the “Light” tab, set “Pedestal” to 100 for all lights. This is a critical technique for maintaining color
