Sketch of Crater Clavius

[Nightjar]

Here's a sketch of crater Clavius on the moon's terminator, made on 8th October. I'll probably redraw it at some stage, to sharpen it up a bit. But this was made entirely at the eyepiece, with a dim red light in a very dark place, heavy dew on the paper, and the temperature dropping below zero.

The exposure time was about 45 minutes, where I'm using the word 'exposure' not to mean 'image capture time', but as in 'suffering from exposure'.

VERY nice! Clavius has a lot of details and you did a wonderful job. Two questions, though. Why use a red light for lunar sketching, and why re-draw your rendering later, it looks great as-is.

Btw, heavy dew used to plague me until I read about observing umbrellas (yes, you read that correctly ) in an article on the Sky and Telescope site:

"Then there's the observing umbrella, not a widely known accessory but one that works. A beach umbrella blocks the chill of outer space the same way it blocks the heat of the Sun. It can help shield all your gear and you too from the cosmic deep freeze. On a still night a thermometer under an umbrella can read more than 10° Fahrenheit (6° Celcius) higher than when it is exposed to the open sky." link

They really work!!

Hi,Thanks Talitha. I used a red light this time because there were several serious looking astro-photographers at the same site ...Never heard of the umbrella idea before. Definitely worth a try, I'll test next time I'm out in the back garden.

Nightjar that is a fine sketch showing very nice detail and nice to see another active sketcher i look forward to more of your work.

Very well done Mick.

Great sketch Nightjar

"heavy dew used to plague me until I read about observing umbrellas :"

I didn't know about the brolley either, nice one Caroline.....I'll take mine out with me next time the clouds clear.

Looks good

You have caught the crater chain really well.

Cheers
