I want to use long lenses to take pictures of the sun. 600 to 1200mm lenses, at mid-day. What are my filter options?
I've been able to shoot the sun at sunset or an hour before; caught Venus transiting the sun and got a few sunspots, but that's obviously been heavily filtered by the earth's grungy atmosphere.
I recall dropping a ND filter in the slot near the rear of the lens, and I remember the filter getting pretty warm. Last thing I want is for a filter to shatter inside the lens.
Amazon and B&H are not much help, and I want excellent optical quality.
Any suggestions?
Thanks in advance!
