Hello everyone,

 

Some of you might recall that I failed to sketch the Moon during August. Meaning, I'd need to sketch the Moon twice in a month to have completed 12 Lunar sketches by the end of December. So, with tonight providing some decent skies I decided to go for number 11. Slim pickings tonight though as the Moon is at 99.7% illumination. In saying that, three craters did catch my eye pretty much straight away.

First up was la Perouse. It was very close to the terminator, and had several interesting features to the North. From my observation, this crater seemed to have a some sort of rocky feature on its central floor that was slightly closer to its eastern wall.

 

Next up were Kapteyn, and Barkla. Unlike la Perouse, Kapleyn's floor appeared rather smooth, and its walls were fairly well defined. For me Barkla was the most interesting of the three craters though as there is a very pretty crater in close proximity to it; Rukl names it Langrenus M.

 

Other details from tonight's session include:

 

Location: Dundrum - Bortle 8
Instrument: f/5 250mm Newtonian Reflector on a Dobsonian base
Seeing: 4pk
Transparency: 3 (Moon was directly over a neighbour's house, and another neighbour had their heater blowing hot air into the atmosphere)
Time: 20:36 - 21:11 UT

 

As always many thanks for taking the time to read the above, and your comments and feedback are always welcomed.

 

Clear skies to all,
Darren.

Darren,

 

Very fine sketch of all  three and the bonus is you included  little Langrenus M at 17km. diameter.

this is a very fine looking sketch.

You did a very fine job in sketching details, but the sketch looks very dark on my screen. Maybe you can make it lighter.

Hello Frank, Michael, Tom and Jef.

Very many thanks for you nice words and feedback. You're right: it is too dark. I was playing around with some of the colour tools in GIMP...always trying something out!

I'll try to lighten it, and we'll see what it looks like. Something tells me it'll be better.

Again very many thanks for the feedback gents, and thanks to all those who liked the sketch.

Clear skies,

Darren.
