Also, make sure the subs are long enough. Improve the Signal-to-Noise ratio (SNR) of the original image - by taking more subs.Use the 'Before'/'After' button to see the effect of the module.try reducing the larger scale settings (e.g.try reducing Brightness Detail Loss - and Color Detail Loss if that doesn't work.make sure the Grain Size (Screen 1) is no higher than needed.Look out for any reductions in the detail - if found:.Look out for any remaining noise blotches - if found go back and check the Grain Dispersion settings.Background noise should be greatly reduced or eliminated without affecting detail significantly.Press Keep to exit, keeping the results.If you make a mistake, the 'Reset' button discards all the changes since you started using the module.

However, if further adjustment is needed then experiment with the following controls: In many cases the remaining parameters can be left at their default values.Select an area to sample to speed up the processing while you adjust the parameters.Click 'Next' - StarTools will do its initial attempt using that grain size with other settings at their default values.Structures larger than the Grain Size are considered detail, not noise. Select Grain Size so the noise grain and clumps can no longer be seen - as described below.(v1.7.416+) Set Walking Noise Size and Angle parameters as necessary so as to eliminate any Walking noise in the image.(1.7.416+) Click the 'Track/NR' module button and select the option for 'Grain removal'.(before 1.7.416) Turning 'Track' off and select the option to 'Grain removal'.This is a way of using the module which should give good results in most cases: Watch out for halos around the stars though.ĪutoDev. Also, try using the Super Structure (Life) modules' 'Isolate' preset with no mask set just before using the Color module then final Denoise module - this will help to push back the noise.It can show you need to go back and redo a step, or do further noise-reduction steps, prior to turning Tracking off and final Denoise. It can show when you have overdone something (like the final Develop/AutoDev module stretch was too aggressive) and too much noise will remain visible even after applying the Denoise module. This allows you to see the effect the Denoise module will have when Tracking is switched off based on the current image. (before 1.7.416) The Denoise module can also be used in 'Preview Only' mode at any time when Tracking is on.
Final Denoise is usually done after the Color module.This relates to v1.5 but is still relevant for this module. The processing video M8 in Color with modest data has a demonstration of the Denoise module between 8m16s and 9m43s. The StarTools video tutorial A simple processing workflow tutorial with imperfect real-world data includes the use of the Denoise module. This allows a high level of control over noise - with extra control over areas of detail. Scale Correlation techniques are used to identify detail.Tracking identifies the areas of higher noise.
The Denoise module uses the following methods to separate detail from noise:
Here are some notes relating to using the Denoise module.
