Jagged Planet offers a range of software products for music, audio and electronics enthusiasts with an interest in generating and processing sound and images. Also on offer are instructions for making your own high-sensitivity long-exposure astronomical CCD camera.

J-scope dual trace


J-Scope is a full-featured VST 2.4 Oscilloscope plugin. A good oscilloscope is an essential tool for developing synthesiser or sound-effects, allowing you to visualise and measure waveforms in an easy and intuitive manner.
J-Scope displays mono or stereo signals, in dual-trace or x/y modes. It has a versatile array of triggering options, a freeze facility, and the expected range of timebase and signal level controls.

IIR Explorer

The IIR Filter Explorer is a tool enabling the rapid interactive design of basic Infinite Impulse Response digital filters. At present, the tool supports Butterworth, Chebyshev (type I and II) and Elliptic filters up to 20th order, in low-pass, high-pass, band-pass and notch configurations.
As well as the visual display, there is an option to audition the effect of the filter on a variety of waveforms. An example 'C' implementation of the selected filter is output, for copying to your own project.

Nebula M27 procesed with iMerge


iMerge is an image-stacking and mosaicing utility. Using an intelligent averaging algorithm, the software uses overlapping regions to provide effective noise reduction. Image tiles can be 'feathered' into each other to avoid visible seams between images.
iMerge is aimed primarily at astronomical imaging - either stacking for noise-reduction, mosaic-making for wide-field imaging, or anything in between.

1004x CCTV module

Sony ExView CCTV module for Astronomy

The 1004x is a small low-cost CCTV camera module, featuring a Sony ExView HAD sensor. This device has excellent light sensitivity in visible and near infrared, making it suitable for budget astrophotography.
For deep-sky imaging however it is necessary to extend the exposure time, and this project describes a technique for modifying the 1004x board camera so that, when used with suitable software, it can take true full-resolution long exposures.

planet image generated by Terrapin


Terrapin is a highly optimised, near-realtime, raytracing fractal landscape generator. It can be used to create images of alien terrains, with mountains, seas, and a wide range of atmospheric effects. It can also generate images of entire planets floating in space, and these planets can be used as a backdrop in a landscape image.
Rendered images can be oversampled for antialiasing, and saved as lossless bitmaps or jpegs.
