A man on a mission to photograph all of Nova Scotia's 175 lighthouses says the project is coming along, but it has its challenges.

Larry Peyton, from Waverley, N.S., set out last year to use his drone to document all of the province's lighthouses.

This week, he hit the 100 mark — which means there's just 75 left to go.

"The project isn't complete until I've captured every one of them," said Peyton.

"Some call me determined, though I reckon stubborn may be more appropriate."

He there have been challenges getting to some of the more remote locations.

"Sometimes things move very quickly, where a stretch of good weather matches an opening in my schedule. Other times, I am hindered by other factors," said Peyton.

"My biggest hurdle now is acquiring assistance with getting to the offshore lights; I really need help from local boat owners in the respective areas, but making contacts is not always easy."

Peyton received help from a young man in Abbotts Harbour, who took him in a zodiac boat to the lighthouses dotted around the Tusket Islands.

But in areas like Cape Breton, Peyton said he's still having difficulty tracking down people who are able to bring him to lighthouse locations.
