(Moved to f-stop to make it a photographic discussion.)

For non-usual moon photographers, here are some typical exposure settings for
a FULL Moon (where slightly more exposure is needed for non-full phases):

ISO: 200
Aperture: f/8
Exposure time: 1/250sec to 1/400sec

Tripod: Not needed if you have good lens stabilisation and can brace yourself against something.

Focal length to use: as long as you can for detail. 400-600mm is useful.
That yields an image about 1/5 to 1/4 of an APSC frame.

What PP?: A full moon has no shadows from craters and mountains except at the very edges.
You'll try to record the difference in tones between the brighter lunar mountains and the darker
lunar "seas". You may need to enhance contrast in PP.

If you want to record an "observation" rather than a "snapshot", make sure your camera's date and
time are right, and add where it was taken from.

Thanks Am - now can you please get rid of the horizon-to-horizon cloud cover...;)

[ameerat42]

Priddy clowdy:eek: here too, Dennis. Lots of breaks, so will see for tonight...

[mudman]

my ephermeris for Canberra, and probably most of the East coast, is moon rise 19.28

Close for Sydney, too: https://www.timeanddate.com/moon/australia/sydney

The heavens have just opened up here with heavy rain forecast - so I guess no chance for me.

[Claire M]

No chance over here in the West either, as it's an overcast sky. :(

[ameerat42]

Darrt! Blarrst! And all the omens! Guess what has also happened here?!!!
Will check it out during the night...

Why does this supermoon thing excite people? :confused013
Just learn how to expose any full moon well and crop a bit closer??

[ameerat42]

Well, I managed a few shots, some through light cloud (not posted) and some in a break.

1. Supermoon, per se...
133628

2. A comparison with the last lunation (with some rough calcs)...
133629

:D What you've suggested Mark, makes a lot of sense, and with no moon out tonight over here, that's what I'll be doing in the future, (when I can see the full moon again).

Why do some people only take photographs of birds :confused013. :D

Sorry Mark – that is unlikely to work due to a phenomenon called “Libration” where the Moon appears to perform a weird rocking and tilting motion in its orbit.;)

Have a look at this YouTube video for a fascinating animation based on real data.

You may have a 5-sec ad before you can skip to the animation.

Or this if the above does not work:

Ah, troo! Not to mention nutation (so duly stuck out), precession of the orbit, and
of salient significance for togs, the real (if ever so slight) change in perspective
with changing subject distance:nod:

[Bear Dale]

Nice moon shot.

[Mary Anne]

Why do some people only take photographs of birds :confused013. :D

I wonder... I would rather know a lot about shooting a few Genres, than a lot about shooting one Genre :nod:

[Mary Anne]

Am that's great work and a very interesting read with lots of info from you and Dennis.
So Thanks for Sharing :th3:
