Starnet++

I think it is an invaluable tool to have when processing your images, and I personally use it all the time, starnet++. Starnet++ used it to remove the stars from his image of the Wizard Nebula, starnet++ it worked astonishingly well. Suddenly, I was seeing starless astrophotography images pop up on Instagram and Astrobin daily, starnet++.

Starnet++

In versions of Siril prior to 1. A python script was available and covered here in a previous tutorial now deleted , but it involved multiple additional dependencies, whereas the new integrated interface in 1. Both v1 and v2 are supported. They must therefore be converted. Unless the force 16 bit preference is set it will convert the output to 32 bit in order to be ready for increased precision calculations in subsequent processing. The output image. Note that in this case, if you have further linear processing to do you will need to note the values of the lo, mid and hi MTF sliders and apply the inverse stretch manually using the Siril console command invmtf. Note that the stride input control is only shown when Use custom stride is checked: it is unchecked by default. The starless image is loaded as the current working image in Siril. Introduced in 1. In theory it can be used to blend any two images together, but the primary design goal was to support workflows involving separate processing of the starless layer and the star mask. The dialog takes the form of two columns, each with a set of generalised hyperbolic stretch GHS controls and a mini histogram display. The mini histograms also show a graph of the transfer function of each stretch, and may be minimized by clicking the drop arrow next to their title.

A starless version of the Omega Nebula. A quick example of this would be to brighten the outer regions of starnet++ Andromeda Galaxy without making the surrounding stars brighter and overpowering, starnet++.

Forgot your password? There is a thread over on CN started by the developer with a link to download the files not entirely sure if linking to a 'rival' forum is allowed, but if you Google "starnet v2" it'll be one of the top results.

He has announced that he has released V2 of the software. The idea was to train a neural network that can remove stars in one simple step, avoiding time-consuming-thousand-steps procedures with dozens of parameters to tune. Since its debut, Misiura has been working with the amateur astronomy community to continuously improve on the software. For Photoshop users the software provides the ability easily drag-and-drop your images into the platform to remove the stars. It can be downloaded on Sourceforge. There is a Python version for more advanced users that is available on GitHub. The whole code is open-source and users need to have the ability to work with Python, Tensorflow, etc. The code provides the ability to train the neural network on your own data or modify the code for your needs. A quick example of this would be to brighten the outer regions of the Andromeda Galaxy without making the surrounding stars brighter and overpowering. It should show better performance across the board, including wide field images of the Milky.

Trying to strech the result of a starless image I see some star artifcats appearing, not sure that is the case with StarXterminator. Once you have run the software on all RGB channels, you can build the full-color image without the stars. Maybe you enjoy the look of a completely starless image on its own. You are using an out of date browser. Log in Register. It's easy! It's much better at identifying and removing larger stars and also leaves fewer and less obvious removal artefacts. The controls behave the same as in the single-image Generalised Hyperbolic Stretch Transformations tool, with 2 exceptions. WeTransfer maybe? I thought that's what I did at first when I installed it into the PI bin file. How did you find that! Get Started Toggle child menu Expand.

Certain subjects are better suited for a starless variation than others. I was hoping to test starnetv2 against StarXterminator but starnetv2 seems to have disappeared from the internet! Once you have run the software on all RGB channels, you can build the full-color image without the stars. Sorted now, thanks Martin! Note that in this case, if you have further linear processing to do you will need to note the values of the lo, mid and hi MTF sliders and apply the inverse stretch manually using the Siril console command invmtf. Maybe you enjoy the look of a completely starless image on its own. The brightest stars still have a background patch of blue behind them, but much better than with StarXterminator. The starless image is loaded as the current working image in Siril. A starless version of the Tadpoles Nebula. He used it to remove the stars from his image of the Wizard Nebula, and it worked astonishingly well. Another challenge is dealing with the halos surrounding bright stars in the field. Probably encodes image in 16 bit after stretch if it is still linear and then converts to 32bit before "unstretching" it.
