The moon two weeks ago - 1 image attached

[William Bottaci]

The moon two weeks ago; it's taken this long to get around to processing it.
Waning gibbous, 2½ days after full moon.
  Age            2½ days after Full
  Altitude      37½º above horizon
  Diameter   32º 58'

Canon R7 with RF 100-500mm L IS lens with x1.4 tele-extender (set to 700mm, f/10, 1/200 sec, ISO 1000) hand-held stabilised.
A provisionally processed single jpeg image.

Given the weather I was lucky to get this in; sandwiched between wanting the moon to rise higher but all forecasts showing cloud rolling in. I've been caught out before when I waited too long. On the plus side the air was much steadier than average, but this was because of the murk in the low wind, which explains why I needed to go to 1000 ISO (and it shows), much higher than I would have liked.
Another plus, the moon has a range of visible size between 29.4 and 33.5 arcminutes, about a ½ degree, depending on how far away it is, and this was on the closer/larger side.

At this time of year the First Quarter is low in the sky, which means Last/Third Quarter is high - except you need to get up before dawn...
Thank you for looking.
William

That's a very nice image William. I'm amazed how well the image stabilisation works with a hand held camera.

Same here.  The focus is spot on.  I particularly like the bright spots on the dark side of the terminator showing the highest tips of crater walls and mountains.

Thank you all; comments much appreciated.
Canon, as with other manufacturers, have improved their image stabilisation and the extra steadiness means I can use a lower ISO sensitivity value. Practice helps, even in daylight on any object, and all the more so if a tree, lamppost, or telegraph pole to lean an arm against.
The focus is a challenge as it's a low contrast object and not easily recognised by the camera. Took me a while and lots of shots before I got something consistent.
So, trial, error, practice; the invisible ingredients.

Thank you for looking.

Once again, needs to be viewed at 100% size, 1600 px, when downloaded for the extra detail; most if not all browsers show a 'quick' degraded image otherwise.
