A wonderful photo thanks to 'Kete West Coast' and the Buller, Grey and Westland District Libraries. Just another example of the need to look far and wide, you never know where these treasures will turn up.
Caption: This image was possibly taken at Thames, and shows the telescope used to (hopefully) track Venus. Surnames include TYLER, WARD, VEITCH, SPENCER, GORRIE, those on the right-hand side of the image are illegible due to fading.A report - THE TRANSIT OF VENUS. - is in the newspaper - Thames Advertiser, Volume VII, Issue 1915, 10 December 1874, Page 2
There is some interesting discussion on the photo at the Kete West Coast site.
