Delphinus is a freeware 16-bit image processing software with many powerful filtering algorithms. It also allows you to control your camera exposure time through RS-232 (serial) and LPT (parallel) port. Program was made as a part of "Pi of the Sky" project which has been realized by Institute of Nuclear Studies, Center for Theoretical Physics of the Polish Academy of Sciences, Institute of Electronic Systems and The Faculty of Physics of the Warsaw University.

Delphinus software consists of four parts
1. Camera control - controlling camera through RS-232 or LPT port (to use this function you have to make a special cable described in a separate tutorial called "Description of Serial and Parallel Port Control Cables" which is available on our website).
2. Converter - which allows you to convert CR2,CRWand RAW les to FITS,TIFF,PPM and BMP.
3. Editor - image processing module which basic functions are described in this tutorial
4. Batch - module designed for compounding images and making animated GIF les.

To control the camera using Delphinus software you need:
1. a computer with LPT or RS-232 port
2. appropriate cable with some electronics in it (a full description you can nd in a separate tutorial called Description of Serial and Parallel Port Control Cables which is available on our website).
3. DSLR camera with remote control port.

Important: Cables that are needed are not typical RS-232/LPT to micro-jack (2.5mm) cables. They have some special electronics in it so DO NOT try to plug any cables you can find. Even if the plugs fit into the sockets it does not mean it will work!

Delphinus Features:

How to plug the cable
Step 1: Turn OFF your camera and your computer.
Step 2: Insert the LPT/RS-232 plug to the computer's port.
Step 3: Insert the mini-jack/N3 plug to the camera's remote port.
Step 4: Turn ON the computer and the camera.

Important: DO NOT try to insert the plugs on running computer or camera. Always make sure that both devices are turned OFF! Inserting plugs on running devices may efect in the permanent damage of the computer or/and the camera.

How to con gure the program?
First of all open Delpihnus software and click Camera control in the Launcher window. At rst you have to choose the appropriate interface: LPT (parallel) or RS-232 (serial). Then you have to select appropriate port number to which you have inserted the plug.

The license of this software is Freeware, you can free download and free use this image processing software.
