Hi everyone. New to Astro and imaged the moon with full frame mirrorless and stacked in autostakkert. during the processing in registax it’s leaving these faint lines as it goes through the process. I tried changing the process area which seemed to help but zoomed in there are still faint yellow lines in the image. Does anyone know what could cause this? I can see the lines appear in real time during the ‘do all’ sharpening. it’s full frame and 45mp so it’s a large file (not sure if that’s relevant)  |

Hi Vishal, I don't know that I see the lines you're talking about. The only faint lines visible in this fine image are the ejecta rays from Copernicus and Tycho, as well as other lines that exist on the Moon. Also, this image is a bit over-sharpened; whether or not this is producing something you're seeing is up to you, but for my money, this is a beautiful image. You might back down a bit on the first and second wavelet layers and see what happens. Beyond that, nice work, mate. - - Steve |

Hi everyone. New to Astro and imaged the moon with full frame mirrorless and stacked in autostakkert. Did you try changing the wavelet filter to default? |

Thank you both for the quick replies! I’ll check if the wavelet filter was set at default and will back down on the sharpening thanks! The lines appear at the bottom of processing area boxes as it goes through it’s sharpening. I’ve zoomed in here to show you.  |

Thank you both for the quick replies! I (sometimes) got this lines using Gaussian Wavelet filter, it disappears when set to default. It's actually a bug in the Registax software that was never fixed. The sharpness is quite fine but now you have a lot of noise. Some sort of noise reduction would help smoothen things out a bit. |

Hello folks, I use registax for sharpening the solar system images with the wavelet filters and have to deal with the same issue. First, use the filter carefully. When they appear I use the denoise function of the filter and ususally get rid of these artifacts. Second, use the wavelet filter with care. Less is sometimes more. i usually use the linked wavelets. It's more tricky, but when you get used to it the results are quite good. Greetings Nik |
