Frame 66, made by ZOND 8, shows Vertregt just left of the grey-white rectangle near the frame's right margin. Vertregt is the large "half" walled plain just south-southwest ("to the right") of Aitken (which is the pronounced crater with dark floor and central peak).
The start sequence of Apollo 17's Fairchild camera magazine REV-36 shows the southern part of Vertregt (frames 1547 to 1554). Of those 8 frames, frame 1550 shows much of the interior of Vertregt K in shadow (local evening terminator).
AS17-150-22961 shows Concentric Crater "N° 20", east-southeast of Vertregt K (on the floor of Vertregt itself). This seems to be the only orbital Apollo photograph of a Concentric Crater mentioned in C.A.Wood's list of CCs, published in 1978.
AS15-P-8854 also shows the Concentric Crater E.S.E. of Vertregt K (near the frame's right margin; scroll all the way to the right).
AS17-P-1915 is another ITEK-panoramic frame which shows the Concentric Crater E.S.E. of Vertregt K.
Concentric Crater southwest of Aitken, also on the floor of Vertregt, see AS15-P-8859, and AS15-P-8861 (this CC is located near the right margins of both frames). See also AS17-150-22964 (because of the high solar illumination in this Hasselblad photograph, the "double walled" appearance of the Concentric Crater is not very distinct). Note that this Concentric Crater is not the same as N° 20 in C.A.Wood's list!

Concentric Crater (CC) slightly east-southeast of Vertregt K (on the floor of Vertregt itself). This is the 20th item in C.A.Wood's list of Concentric Craters (1978).
Concentric Crater southwest of Aitken (also on the floor of Vertregt). This Concentric Crater was not included in C.A.Wood's list.
