The Tolansky Crater...

Professor Samuel Tolansky was Head of the Royal Holloway Physics Department from 1947 to 1973. He was one of the Principal Investigators who studied the moon dust brought back from the Apollo missions, and a 13 km diameter crater not far from the Apollo 14 landing site was named in his honour.

...Photo Contest!!!

The moon is 383000 km from earth, so a 13 km crater subtends 7 arc seconds. Given that this is well within the reach of a small telescope, John Underdown has proposed that we have a contest to see who can take the best picture of the Tolansky Crater.

The competition is open to all RHUL students and staff. Please submit your entry to Professor John Strong, Head of the Physics Department, by 24 May, 2002.

The prize???

Good question. Somebody please suggest a prize.

My entry...

So here is my photo of the Tolansky Crater, taken 22 February 2002 using the Physics Department's LX200 and QuickCam CCD, here is a line drawing of the area, and here is a photo of the entire lunar surface (by Lick Observatory) showing where this is located. And here's another attempt at Tolansky from 22 May 2002, a fairly windy night.
