I recently started using a Orion Skyglow Astrophotography broadband light pollution filter on an unmodded DSLR and I'm having trouble with the color balance. Here is a link to a pic of M42, but I feel like it should have more red. I use PixInsight's Dynamic Background Extraction, Background Neutralization, and Color Calibration and that left me with a washed out image. M42 I did try to pump up the saturation and that helped some but the emission nebula area is more orange than red. Has anyone else had color issues with a LPR and DSLR combination? If so, how did you solve it? Comments and critique are appreciated. Thanks, Nathan |

Your background still has a small blue/red color cast. You can try this to balance the color before DBE: - Open the stacked file - Extract the RGB channels - Open statistics and check the 'median' value of each channel and note which channel has the lowest value - Open the LinearFit tool and select the channel with the lowest median as the reference - Apply this to the other two channels - Open the ChannelCombination tool and select all three channels - Click the ApplyGlobal (circle) button to create a new, channel-matched image. |

Thank you Victor! I'll give that a try. |

I took Victor's advice about extracting RGB above and also was very careful using ColorCalibration to only use an area with unsaturated stars for the white reference. Those two things helped. I also tried splitting out the L and processing it separately from RGB an then recombining it. I think I brought out a few more details that way. Here is the new version: M42 |
