Procyon@home.nl Psion series 5 Astronomy program
Latest update: October 3, 1999

Procyon X Pro

You may be currently using the Light version of Procyon. This version is Freeware.
You can use this version in it's present state for free for as long as you like and you do not need to register to keep using it.

However, it is your choice to consider this version as Shareware and register to receive a 5PROCYON.KEY file. This file switches the Freeware version to the Registered PRO version. You will also need the separately available Auxilary pack with additional databases.

Registration is a one-time process, once you receive your 5PROCYON.KEY file in your email (it's only a few bytes) you copy this to the same directory containing all the files. Every new version of Procyon X will detect this Key-file and switch to PRO mode. Therefore all future versions are free, once registered.
Of course you can also get all future Procyon X light versions for free.

Extra's in PRO

Extra's in PRO

Search for constellations

You can search for any constellation and the constellation will flash indicating all the stars which are part of it.

Is it visible yet?

Calculate if the Red Spot is visible and show it on the face of jupiter. You can adjust the Longitude of the Spot.

View any Lunar eclipse

You can find out when the next (or historical) Lunar Eclipse will occur and show the actual view of the face of the Earth hiding the Sun.

Real Messier objects

Actual pictures of all Messier-nebula instead of only a picture representing the type.

Massive NGC database

Search in the entire NGC catalogue (more then 7800+ items) instead of only the first 100.

Unreal precision

Precision is always within the planetary- disc and most of the time the High precision mode up is to an arc-second.
Actual data may vary, we're continually upgrading the precision.

Extended Zoom-in

Reference Stars in Zoom-window up to magnitude 7. So you'll always find what you want in your scope.
