For what it is worth I have created a project on SourceForge
(http://sourceforge.net/projects/messier/) with my Astronomy Program.
It is a basic Observing Planning and Logging Program. It is of course
written in Lazarus (I converted it from Delphi) and got most of the
Algorithyms from "Practical Astronomy with Your Calculator" By Peter
Duffet-Smith.
There are two major things I would like to add to it:
1. Using a report generator instead of Printer.Canvas.TextOut
Statements.
2. I would like to merge it with Planetarium Program. I could do this
with Cartes Du Ciel 2.76, but not the newer SkyChart and since my
primary audience is going to be Linux Users, I really don't want to
use a Windows App.
You can always try lazreport. I have a cross-platform app working with
it.

Thanks for the suggestions.
I have looked at RTF when it was a Delphi App. I found it would loose a
couple lines of the report at page breaks, maybe the Lazarus Component
is better. I have also looked at Lazreport, but don't know enough about
how to do it. In the RiseAndSet Report, the select is exported into a
binary tree for update and then sorting. I had to do this for
performance and was unsure of how to import that into something like
LazReport. As far as supporting a Windows version, there are already
many apps that do this in Windows and a lot better then I can (Some for
the Mac too. ) Most of them have huge databases (1 million + records)
which I have no idea how to put together. The databases I have are
pulled out of Excel Spreadsheets and messaged in MySQL. As far as
importing into Excel/OO Calc, I have exported data to csv and then
imported that, but its a lot of trouble for the user. I do that though
for the standard report, which can be submitted to the Astronomical League.
