Re: [APML] Sun filter: Venus transit
Chris, Nicola, thank you very much for the response.
Chris, I like your pictures of the mercury transit. Although there is
only in-transit images, not ingress nor egress. What can I expect to see
in these instants? I've read somewhere something about a "black drop"
effect but I didn't understand whether it was a visual effect or a
distortion produced by the lens or due to some physical phenomena.
Cheers,
Pere Sanz
