Okay, so I've set out on a bit of a weird endeavour. The below Apollo 11 photograph (AS11-37-5445) was taken over Craters Taruntius K, Taruntius P, and Dorsum Cayeux (in Mare Fecunditatis) with craters Anvil and Taruntius H being partially visible.

Essentially what I am trying to do is:

  1. Find the position of this site on a lunar map (high def image, ideally 300dpi) so I can pinpoint where the photo was taken.

  2. Find the direction of the orbit in which the Apollo CM was travelling at the time.

  3. Find out exactly which orbit this was when the photo was taken (I'm not sure how many times the CM orbited above while Armstrong and Aldrin were below).
I would appreciate the help!

Position is between 49E and 52E on Descent Chart. Flight path is from bottom of photo towards top (E to W). Don't know orbit number. [Original of this segment of flown Apollo 11 Descent Chart is in my collection].

Thank you, that answers part of my question! I don't suppose you know where I can find a copy of a complete Apollo 11 descent chart?

AS11-37-5445 was taken by Neil Armstrong on revolution 13 at approximately 100:33:20. This was roughly 6 minutes prior to the CSM performing the RCS separation manuever. The CSM attitude was nose down pointing at the centre of the Moon.

I have a location map which I can send if you could provide your email address.

Hope this helps. Intrigued what you need this info for?

That is perfect, thank you! My email address is moonandmars@hotmail.co.uk

I can't reveal the exact reason why I need it (yet), but essentially I'm creating a type of storyboard for this part of the mission and I am trying to gather as much relevant data as I can.

This photo is one of 4 taken in sequence, so I'm trying to map each one but felt it would be easier to start with one.

The sequence is:

AS11-37-5443
AS11-37-5444
AS11-37-5445
AS11-37-5446

Give me a few minutes and I will provide maps for all of these.

Are you referring to the lunar module here? The path of the CSM seems to be different from the position you're referencing. I've superimposed the photographs directly onto the chart as part of my efforts and I "think" it takes the CSM on a different path?

Yes, reference is from LM Descent Chart which shows position over this site at 3.5-2.5 min before PDI, undoubtedly on a later orbit.
