A large number of friends have contributed greatly to the project.
Larry Bell derived a formula to correct
coordinate conversion hysteresis when large values of Z1 and Z2 are
used.
Richard Berry suggested the 3 star initialization routine.
Renato Bonomini contributed the eyepiece and eyepiece focusing
code.
Jack Brindle and a small group are actively working on a
Mac port loosely based on the computerized dob project.
Doug
Brown contributed code and circuitry plans for 5 phase stepper
operation.
Tom Cathey worked with me on the encoders.
Marcello
Cucchi and friends contributed a program that generates a planetary
positions data file.
Gilles Cotes contributed NGC/IC data files.
Donald J. D'Egidio contributed the AL_DblSt.dat and AL_Urban.dat
data files (Astronomical League's double star and urban club object
lists).
Ben Davies contributed precession/nutation/annual
aberration formula and code.
Dale Eason contributed fast video
routines and interrupt timed slewing, in addition to the Messier and
stars to 5 mag data files.
Dave Ek contributed the altitude
offset algorithm.
Mark Ewert contributed code for site
configuration.
Bill Gray worked closely with me to integrate
"Guide" with scope.exe.
Berthold Hamburger designed a
PCB.
David Hutchinson contributed custom LX200 commands.
Rex
Kindell worked on most of the data files, checking the declination
minus situation; also contributed the solarsys.exe program..
Tom
Krajci helped with the pointing error corrections, homemade worm
gears, and contributed the bright stars catalogs.
Jerry Pinter
contributed many of the object data files and worked with me
developing backlash routines.
David Lane helped me integrate his
MGIII encoder project with my system.
Bob Norgard contributed the
NTE1857 replacement of the SAA1042 chip: its wiring and notes.
Vicent Peris contributed the Hickson Compact Galaxies, Palomar
Globulars, Arp's Peculiar Galaxies, Catalog of Planetary Nebulae, and
SAC60 by constellation data files.
Jon Rock showed how to use the
mouse encoders.
Chris Rowland for source code on unique PWM
values for the 2nd motor, and for many additional scroll commands.
Bob Segrest developed a microprocessor based encoder interface of
great speed.
Chuck Shaw helped develop the field de-rotation
system, spent time debugging the autogeneration of PEC routines, and
has worked to develop a set of configuring instructions.
Pat
Sweeney developed a PCB for the project.
Dave Sopchak contributed
the iterative altitude offset algorithm.
Jean-Charles Vachon
contributed the current limiting circuit.
Don Ware contributred
the Flamsteed data sets along with NGC and IC1-5 data sets; and
source code to read forwards/backwards through the data files; and
the user defined hotkeys; and the polar alignment method for
equatorial mounts; and more.
Mark Williams contributed the
autosynchronization of PEC idea and code.
Members of the
scope-drive@yahoogroups.com
list have contributed many ideas including hardware circuitry and
operation suggestions.
Many other amateurs have made suggestions
and worked with me to perfect parts of the system.
