Hello Tony,
I agree with you that the dipleidoscope is "crude" but is simple and
effective.
About fixing position against the star I have all the hardware (maps,
atlas, bincoulars, telescopes) I need and I think to develop some skill
in a short time, but the problem is to manage the data.
In other words, I don't want to setup a tracking centre in my
backyard/office, but I'd like to develop some considerations using my data.
Let's stay in the period determination from tracking data.
I have read the King-Hele book you quote me - this in one reason why I
am so hooked with satellites ;-) - but it's not very technical.
On the other side it's a bit discouraging to get book of general
celestial mechanics and find my road there, I'd need probably years ...
I'd like to read something intended to taught people in that specifical
task, probably.
I am getting all the books I can find in the web but I have not found my
asnwer ... :-(
Any help will be welcomed.
Clear skies to all
