"Big moon day June 23"

I know nothing about astrophotography, but understand that the moon will be closest to the earth on June 23. Perhaps this means nothing, but could one expect it to appear closer as well?

Hi William,

On June 23, the apparent diameter of the moon will be 33' (arc-minutes). The typical minimum diameter is about 29-30', so the moon will be about 10% larger in apparent diameter than it is when furthest from the earth.

I don't think it looks visually larger to the unaided eye. And it is confused by a psychological effect that makes any moon close to the horizon appear much larger than it looks high in the sky.

Photographically it is like a free 10% focal length boost . It is interesting to shoot a "large" moon like the June 23 moon, and a moon at 29-30' apparent diameter, at the same focal length and with the same camera, and compare comparable crops.

Alas, the forecast here for the evening of the 23rd is "Mostly Cloudy."

I always wondered how that differs from "Partly Sunny".

Anyway, it's expected to be raining here (surprise )

Well, it's an evening/night forecast, so "Partly Sunny" would qualify as quite a surprise!

"partly sunny" - an optimist

"mostly cloudy" - a pessimist

Decided to try to catch the moon on the horizon at the airport with the telescope (~1000mm f/8). But, the murk was too thick on the horizon, and by the time we could see the moon, 1000mm was already too long to make an interesting shot. And, even in this shot, the moon was really dim.

D600, 5" refractor, 1000mm, f/8, 1/20 sec, ISO 3200
