Last night we saw the new Apollo 11 film at the Waterloo Imax. While many of the pictures didn't really scale up very well to Imax it was still very impreesive. All the footage apart from a few graphics was original, not reconstructions. Less impressed withthe sound. The music they added IMO detracted from the film rather than enhancing it.

Then in the news they aanouced the sale of some original VT recordings of the landing: https://www.theguardian.com/science/2019...early-lost Looking at the tapes and their labels in other reports these are 525 line NTSC recordings made on an Ampex 2000 quadruplex machine.

" Apollo 11 tapes bought for $218 may sell for millions after nearly being lost

Tapes identified in 2008 as the only surviving original recording of the first moon landing in 1969 are to go up for auction in July"
On my 'to see' list!
I understand a lot of the original footage was shot on 70mm film so quality should be pretty good.

There's an interesting talk with Stan Lebar at the Early Television Foundation
in 2009,it's quite long and difficult to hear at times.The second half of the video has the most information relating to the camera.
Stan worked for Westinghouse and they developed the TV camera used on the Apollo missions.
Video incoming from the moon was 320 lines,10 frames a second transmitted in a 500KHz bandwidth (all Nasa had available).
Conversion to 525/60 was done at the ground stations before being sent on to NASA and Stan mentions this is where a lot of the degradation happened.
The original incoming 320 line video
was recorded on tape but got lost,mislaid or even wiped.
Stan sadly passed away a few months after this recording.
Mr Hoover, thanks for the info. I'll need to take a look. I know about the slow scan. Conversion to fast scan was optical. Camera pointed at monitor stuff. The first colour footage fom the moon was (I think) Apollo 12. The camera used a single tube and colour wheel. Like the short lived 1948 CBS system. A compact 3 tube camera just wasn't possible back then.

Alan, some of the material looked very good on the Imax screen.Some of it didn't. That's inevitable. Just good that we've got this footage at all.

I managed to bag a couple of (free) tickets for this event with James Burke.
It's possible that Ruth might not be able to come with me so if anyone is interested and available on the day please let me know by PM. Not making any promises. Getting in to these BBC events is a bit of a faff. The ticket doesn't guarantee admission. You have to turn up fairly early, wait in the queue and get processed. Never yet failed for me at things like the News Quiz recordings but did get turned away last year from BBC Maida Vale where they'd overbooked heavily.
Apollo 12 had the problem with the camera (Stan talks about that) 13 didn't land so it was probably 14 that had the colour one.RCA were involved later on in the Apollo missions camerawise I believe.
Stan mentions there was a still frame colour relative HD image facility in his camera using RGB filters via a timer but NASA never used it though it was a contract requirement.
Not TV related as such but a group is doing the
restoration of the Apollo Guidance Computer.
Quite a few videos now,here is the link to the first one.

Yes, I remember that very well. It looked as if the camera was pointed directly at the sun when it was on its way down the steps of the LEM.

That's instant destruction for a vidicon tube, even with 50 miles of the earth's atmosphere between tube and the sun, let alone unfiltered sunlight on the lunar surface.
Stan goes into that in some detail, there was only a few degrees of separation between the sun and the earth at the time and they were trying to point to the earth.
The astronauts had very little training on how to use the camera apparently,Stan was in an adjacent room to mission control,heard the beginning of the conversation about lining up on the earth,tried to stop it but was too late!
The original Mission Control room has been restored.
