I wanted to compare the just now released beta1 release of SNR by NeuralCelestia with the well known and excellent StarXTerminator on a rather difficult target - SH2-136. It contains a lot of stars, one extremely large star, one hidden by the nebula and another large one in the nebula. Both SW did not perform their removal action to 100%, SNR did not remove one of the larger stars and left instead of the stars small blotches, SXT removed that very same star and left larger blotched. Both results need a larger amount of afterwork to make it usable - what is to be expected. My personal preference remains with SXT, but that is my opinion only. And to be fair - the new version is the very first beta release. Judge yourself.... :-) CS, Georg The upper screenshot is the new SNR software and the lower screenshot is SXT   |

Both are impressive results! But after how well sxt cleaned up my m33 shot (and you know how many stars there are there) I don't know if I'll ever need anything else. Unless, of course, Russell improves on it. Great comparison! And thanks for doing the legwork! Abundant clarity, Tom |

Thanks - my interest in testing that new SW is because if you eliminate stars from a stack, those residuals remain and they need quite some time to get rid off (more or less). If you eliminate the stars from a RGB image, those residuals usually have a somehow different color than the surrounding area which makes correction even more time consuming - if you go for a more or less perfect starless image. I was wondering if that new SW would do it better....nope, not at all, despite the claim - we use AI for removing all stars.... let´s see if the upcoming releases will improve it. But currently, I am very happy with the SXT... CS Georg |

Hi Georg Sorry if my post appears to be somewhat off-topic, but it seems that you are using a QHY camera (without a built-in UV/IR-Cut filter) and you haven't explicitly included such a filter in your imaging setup. I've come to this conclusion based on the noticeable microlensing artifacts around Theta Cepheus in your image. I'm sure that no star-removal tool will be able to handle this. I recommend trying out this filter. It took me a while to understand that this was also the case with my images (see also this topic) cs, michael |

| Looks to me to be very similar results to Starnet. Those splotchy leftovers are why I don't use starnet anymore. |
