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. Howard

No offense, but this very hard to read.

Howard, Please don't reply this post. Just try to edit it. When you'll get to the editing window copy from the first pre on, then paste it to your own post. Make the necessary corrections and changes you like. When you're done, I'll delete this. Regards,
Gerson.

site would not accept my edit, only a few corrections are necessary following your numbering of pgm steps. HO12 should read 1.0027, EOO4 should read X exchange Y , every thing else OK, thanks for your help, Howard ▼

Fixed! You might want to take a look at advanced formatting techniques. Regards,
