PIPP is a lunar and planetary image pre-processing tool, its primary use is to help speed up image stacking of large video files obtained when capturing images of the Moon or planets.

The main functions of PIPP include:

• Cropping frames to an area of interest, removing all the empty black space.
• Centralising an object such as a planet or the Moon in case of tracking drift.
• Quality estimation and reordering of each frame to ensure only the best frames are included in the final image stack. The number of frames that should be kept can be specified by the user.

PIPP does not output a final stacked image but helps prepare a video file or set of images for planetary or lunar image stacking software.

Support for PIPP has now been withdrawn by the developers and the original website is no longer available. However, there is still a large user base and archived links to the last released version are still available and are linked below. 

As PIPP is still a popular tool there are numerous how-tos and tutorials available online for you to find.

Archived details and links to the last downloadable version are available at the following website.
