Apollo 11, Houston. Our procedures guys are saying that the reticle does not have to be parallel. Over.
- Charlie Duke (CAPCOM)
-
Apollo 11, Houston. We would like you to accept this one and every mark thereafter. Over.
- Charlie Duke (CAPCOM)
-
Roger. We'd like six marks on star 45, Mike, and then we'll probably go back to star 2 again. Stand by. We'll have further word on that.
- Michael Collins (CMP)
-
They seem to be getting smaller, Charlie. Are you sure you wouldn't like some more?
- Michael Collins (CMP)
-
Okay, Charlie. There's your two more marks. Where do you want to go from here?
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11, Houston. We'd like you to go back to star number 2 with an attitude as follows: roll 1952, pitch 1239, yaw 3400. Mike, that'll give you a trunnion angle of about 31.4. Over.
- Michael Collins (CMP)
-
Okay. I understand star number 2 and roll 195.2, itch 123.9, and yaw 340.0. Over.
- Michael Collins (CMP)
-
Okay, Charlie. I'm there, and I've got a trunnion angle of 30.5 degrees. Again, misaligned considerably in roll and I do believe that's important to getting good marks.
- Michael Collins (CMP)
-
See, if my reticle's not parallel, then I'm not marking normal to the horizon and I'm not marking at the substellar point. I'm marking off somewhere else.
- Charlie Duke (CAPCOM)
-
Apollo 11, Houston. The ground-computed values for your shaft and trunnion are just what you're getting on the DSKY there, Mike. The horizon looks cocked off to you—You look like you're off in roll because the angles that we gave you to maneuver to, to prevent LM reflection from fouling up your optics, we feel like a—You should go ahead and mark on the stars just as is. Over.
- Charlie Duke (CAPCOM)
-
Apollo 11, Houston. We'd like to accept this one and give us two more and that will be enough. Over.
- Charlie Duke (CAPCOM)
-
Apollo 11, Houston. We see your termination on P23. Thank you very much. Mike, we'll have a—We're trying to work up a story here for you; we'll be with you momentarily on an explanation of what's happening. Over.
- Michael Collins (CMP)
-
Okay, Charlie. It just appears to me that you have to have a reticle tangent to the horizon at the point at which you mark or else you're not at the substellar point; you're off laterally, and therefore you're measuring a larger trunnion angle than you should.
- Charlie Duke (CAPCOM)
-
Seems so to me. Our procedures people are working on this, and we'll be back with you momentarily. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. We'd like you to go P00 in ACCEPT. We'll have a PTC REFSMMAT for you momentarily. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. We're through with the load. You can go back to BLOCK.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. We'd like you to do a P52, option 1 preferred, and establish PTC as listed in the flight plan at 12 hours. We'd like you to commence that right now, Mike. And we have some stars recommended for you. For stars 26, 30, and 24, when you get to attitude 000. Over.
- Neil Armstrong (CDR)
-
Okay, Charlie. He's off the wick right now. Understand you're ready for us to do a P52, option 1?
- Neil Armstrong (CDR)
-
Roger. And, let's see, that is Spica, Menkent, and what else?

Roger. Stars—Codes are stars 26, 30, and 24. Over.

Hello, Apollo 11. Houston. We notice your PROGRAM ALARM, Mike, was due to using these stars in the P23 attitude. If you'll go to 000, the stars we gave you will work. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. Prior to you starting your P52, we'd like to give you a new CSM state vector. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. You can do the VERB 66. The computer is yours, and then the P52, option 1 preferred. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. If you read, this attitude 000 is pretty bad for our COMM. In fact, we've lost all data with you, and unreadable on the voice. We recommend you do the P52, option 1 preferred …
- Michael Collins (CMP)
-
… not a very good attitude at all for COMM, and as soon as we finish our alignment, we'll maneuver it to a different attitude. Over.
- Charlie Duke (CAPCOM)
-
Roger, 11. We copy. Recommend you go to this P52, option 1 preferred, and then go to PTC attitude. Over. Then we'll get some COMM. When you get there to PTC attitude, it'll be pitch 90, yaw 0 on the high gain. Over.
- Michael Collins (CMP)
-
You're loud and clear, Charlie. We pitched down some to get a better COMM attitude.
- Charlie Duke (CAPCOM)
-
Roger. Did you copy our recommendation on proceeding with the P52, Mike? Over.
- Michael Collins (CMP)
-
Roger. The reason for delay, Charlie, is that—difficult to find two stars that are not occulted by the LM and also are not in the midst of a manmade star field up here with dumps.
- Michael Collins (CMP)
-
Okay, Houston. That completes the P52. We verified the third star with Antares, and AUTO optics are pointing at it pretty closely. How do our platform drift angles look so far, Charlie?
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. We didn't have a chance to get a good check for you. We're going to run a drift check from this alignment until the next one, approximately 12 hours, and we'll have something for you later. Over.
- Charlie Duke (CAPCOM)
-
Hello, Apollo 11. Houston. We'd like you to establish your PTC. We recommend you select quads Alfa and Delta. Over.
- Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Would you verify that the ATTITUDE SET switch is in GDC? Over.
