• Starnet++ is a small but powerful software, created by amateur astrophotographer Mikita (Nikita) Misiura who changed forever the way of post-processing deep sky images. The mighty program removes the stars while retaining the underlying structure and details of the image. Starnet++ can easily add as a plugin in various programs as Adobe Photoshop, Pixinsight, Siril, etc. but there is also a stand-alone version.

Russell Croman, an amateur astrophotographer, created a variety of plugins for astrophotography designed to work with popular image processing software like Adobe Photoshop and Affinity Photo, as well as specialized software like PixInsight. The plugins automate and simplify some of the most complex tasks involved in astrophotography.

• BlurXTerminator is a powerful deconvolution tool that uses artificial intelligence to sharpen and enhance astronomical images. It recovers as much detail as possible based on low-contrast information actually present in an image, without fabricating detail that does not in fact exist.

• NoiseXTerminator is a fast and easy-to-use AI-powered noise reduction tool specifically for astrophotography. It can perform natural detail enhancement without boosting noise or inventing nonexistent structures.

• StarXTerminator is a tool to remove stars from astronomical images that work in Photoshop and PixInsight. This allows separate processing of stars and background objects.

• GradientXTerminator is a gradient removal plug-in for Photoshop and Affinity Photo that is fast and easy to use. It can process 16-bit or 8-bit images, grayscale, or RGB color. It easily removes light pollution, vignetting, and circular gradients.

• StarShrink is a plugin made for Photoshop that shrinks fuzzy, bloated stars.

Planetary imaging is one of the most satisfying aspects of astrophotography mainly because you get to practise so often. Light Pollution? No problem! Full moon? No problem! But also needs a lot of patience and persistence, as it can take time and practice to capture the best possible images. Large focal length telescopes, good and fast cameras and also the most powerfull laptop available are essential parts of Planetary imaging. Here is the best software for imaging planets and post processing your hard earned photons.

Registax is a popular image processing software for planetary and lunar imaging. It is designed to align and stack multiple images of celestial objects, such as the Moon, planets, and the Sun, to create a high-quality final image with improved detail, contrast, and sharpness. Registax offers a wide range of features and tools for image processing, including:

• Alignment: The software aligns multiple images by analyzing the positions of specific features in each frame, such as craters or other landmarks.

• Stacking: Registax stacks the aligned images to improve signal-to-noise ratio and reduce noise.

• Wavelet filtering: This feature allows users to enhance fine details and sharpen the image by applying wavelet filters at different scales.

• RGB processing: Users can adjust color balance and saturation to create vivid and realistic images.

• De-rotation: This feature compensates for the rotation of the planet during the imaging session, resulting in a sharper and more detailed final image.

• Comet alignment: Registax can align images of moving objects, such as comets, to create a final image with improved detail.

• Post-processing: Users can further enhance the final image by adjusting contrast, brightness, gamma, and other parameters.

• Batch processing: Registax can process multiple image sequences in a batch mode, saving time and increasing productivity.
