Altitude/Azimuth pgm, Part 1 for35S « Next Oldest | Next Newest »

 ▼ Howard Lazerson Member Posts: 55 Threads: 12 Joined: Aug 2007 08-20-2007, 06:59 PM pgm converts RA & DEC of celestial objects to Altitude & Azimuth. I use it for a small scope I take on vacation. Each command is seperated by a comma below. lbl H,fix 2, input U,input D, input L, 6.619 , rcl D,0.0657, * , +, rcl U, 1.0027, *, +, rcl L, 15, /, -, 24, X exchange Y, X less equals Y, -, STO W, input R, rcl W, rcl R, -, 15, *, sto X, rcl X, sin, stoY, input C, sin, rcl T, sin, *, rcl C, cos, rcl T, cos, rcl X, cos, *, *, +, asin, sto V, rcl V, sin, rcl C, sin, rcl T , sin , rcl V, sin, *, -, enter, rcl T, cos, rcl V, cos, *, /, acos, rcl Y, X greater or equal 0 ?, xeq Eoo1, Roll down, xeq foo1, lbl E, roll down, 360, X exchange, -, sto W, lbl F , sto Z, view Z, rcl V, view V, rtn , Z=azimuth in decimal degrees, V= altitude in dec degrees, U= GMT in decimal minutes, ie 4hours 15 minutes=4.25, D = day number, L = longitude of observor,T = latitude of observor, R= RA, C = declination-both in decimal degrees. In part 2 I will explain how to use pgm. I am not an engineer etc so I am sure people will come up with shorter/faster changes- also I cant actually label the various names like I CAN IN MY 42S , HOPEFULLY someone can show us how to do this on the 35s?! I have used this pgm for past 3 weeks and it gets me within a few degrees of the object.

HO12 should read 1.0027, EOO4 should read X exchange Y , every thing else OK, thanks for your help, Howard ▼ Gerson W.
