For Photoshop users like me, you can just use the application on its own, and simply drag-and-drop your images into the tool to remove the stars. The software is very simple to install and run on a PC.
The image must be a Bit TIF file. I think a few other file types work, but stick with this exact format for now. You can check the status bar to see the progress of your image. This is a copy of your original image, but without the stars! The starless version of your image will populate in the StarNet directory. Once you have run the software on all RGB channels, you can build the full-color image without the stars. In my experience, this technique produces a better overall result because the tool can better isolate the stars in each color channel.
It does take a little longer, however. Here is an example of the results achieved using this method on the Lagoon Nebula. You may also find it useful to create a starless version of your image during the star minimizing stage of your workflow. Minimizing stars is one of the last edits I make in Photoshop. Said star mask with a little tweaking can then be used with Morph. Transformation and MLT to erode stars away in your linear images.
Blending the two images can be tricky, and the process involves using star masks to do it properly the Select and Mask tool is perfect for this. This can be a very time-consuming process, especially when there are bright areas of your subject such as the core of the Orion Nebula that glow at the same brightness as the stars.
Another challenge is dealing with the halos surrounding bright stars in the field. I recommend copying and pasting your original image as a layer on top of the starless version as shown below.
Separate your starless version into a new layer in Photoshop. However, it will dim all of the stars in a very unnatural way. We need to make a precise selection around the stars to control their brightness and overall impact to the image. To do this, I recommend creating a star mask using the color range tool in Photoshop. Then, use the Select and Mask tool to refine your star mask as shown in the example below. The original star mask that you created by selecting the highlights of the image will likely include the brightest areas of your nebula or galaxy.
For complete control over your image, create a star mask that allows you to copy just the stars in the image to a new layer. Then, you are able to adjust both the brightness and size of the stars independently from the rest of the image. Of course, this technique can have varying degrees of success, depending on the type of object you use it on, and the precision of the star mask you create.
It allows you to manipulate the color and detail of your subject without worrying about increasing the size and brightness of the stars in the field. I have found it to be a fantastic way to create a luminance layer. We have dedicated team of designers who take cares of every person taste and requirements.
