Hello, i am new to this group - although i have spent a fair bit of time over with the Large Format Crew. I am on a business trip to the USA in a couple of weeks time and I plan, once I have been to B&H to collect a new Gorillapod focus, to attach my RRS Ballhead and RB67 to it, and try to take decent timed exposure at night from the observatory of the Empire State. I know...The picture has been done before, a million times probably...but not by me!! I know there is a restriction on Tripods in the observatory however... 1) is there any form of rail up there i might get a gorilla pod wrapped around? (i was there about ten years ago so i can't remember) 2) am i gonna get carted off to Cuba for attaching something to the building? 3) am i mad considering this approach 4) is the shot likeley to be ruined by (i seem to remember) the fence? Thanks!!!
