In general I have only a loose overall plan for my observing aims on a given night – but I often surprise myself with what I might ultimately end up doing.........

 

Such an outcome last night......by late evening Storm Brendan started to ease and a fair to good clear sky developed. Still a stiff wind by 10 p.m. but thought to check up on faded Betelgeuse (close to mag. 1.5 I reckoned).....and Orion’s stars not too flickering in spite of Brendan........!

 

Anyway I was sorely tempted to risk the wind and possible downpours and get a look at the Moon with a long delayed high power follow-up on crater Gutenberg which the VMA showed close to the terminator.

 

See this Link for why I wanted that, hoped for, better view...... https://www.cloudyni...-magnification/

 

The wind was from the SSW and that is about the best for the house to shield the observatory – and was indeed very still there; so set about that Gutenberg quest.  Finding it too far from the terminator for what I planned...but I was struck by the sunset shadowing in and around Goclenius.  My favourite Lunar/Solar lighting effects which lend very well to my stumping techniques.

 

Took me over an hour getting the sketch and as the seeing improved detail was getting pretty daunting – especially with being ever mindful of the weather situation.  As it turned out that poorer-seeing start allowed quicker laying in of the main feature outlines; so was not at that point too compromised by my fine-detail hunger (greed even!) with my usual planet observer’s mind-set! 

 

In the D-K such fine detail that the Moon offers in the best conditions is likely why I do so little with it – not inclined to miss anything for the sketch risks a burnout with me alas.....One reason I tend to concentrate on colours on planets is that it somewhat sates that fine-detail ‘greed’.

Wow! That is one of the best Lunar sketches I have ever seen. Well done!

Stunning technique! I can see it shimmering in the eyepiece.

Much appreciated John, James, Ivan,Tom, and those who Liked.......smile.gif

 

That is a fascinating area around Gutenberg........alas that crater likely too

deep in shadow tonight - but a clear sky unlikely it seems for any of it I fear.

 

Part of Gutenberg - the original objective - is included on the extreme left of

the sketch......Gutenberg E peeking in!

 

Dave.

David,

 

A most remarkable detailed sketch of crater Goclenus.

Thanks for posting it here.

 

Frank :)

Hi Dave,

 

I've always liked your sketches of planets, but this sketch of the moon is really something else. I am amazed by your skill. You have produced an image that would rival a photograph: The rilles in the sketch are incredible!

 

Very well done, and thank you for taking the time to produce this masterpiece, and to share it with us.

Darren.

Hi Dave,

thanks for sharing this excellent sketch! I like the rilles in the upper left part most.

Clear skies

Many Thanks Frank, Jef, Martijn, Darren, Achim.......

 

A deal too windy for further observing – even though no official storm announced currently...

....but looks promising come the weekend.

 

Cheers,
Dave.

That is awesome. I thought that it was a photo at first.

Truly outstanding Dave! Did you add a little Gaussian blur after the sketch? bow.gif waytogo.gif

Thanks Pedro, Clay..........Dave.....smile.gif

 

 

 

Truly outstanding Dave! Did you add a little Gaussian blur after the sketch? bow.gif waytogo.gif

Thanks.............but no Gaussian Blur......

 

Several factors as to why you might think that.  Firstly I’ve over-stumped some areas; not being used to the untried 50-yr old (!) paper (Goldline 200gsm cartridge) used, also seemingly ragging the fabric slightly. 

 

Then there is the increasingly vexing compression problem (Corel x7/Win 10 corrupting) for lo-res posting.  The soft edge to the sketch area is where I used an eraser (against a straight edge) to tidy/clean it.

 

Corel has many blur tools that I have come to avoid using anyway, thanks to the corrupting Win 10 updates: Smart Blur is still the least affected......

 

Even so would not have messed with the sketch in that regard anyway – the only direct computer work being adding the tint in Corel Photo Paint. That proceeds after desaturating the bluish tint of the camera shot (done in good daylight).  Apart from that what comes from the drawing board I want remaining inviolate as far as possible.....bad enough the lo-res issues.

 

Please bear with me folks: I’m still a Lunar-sketching virgin (maybe <dozen crater sketches in ~ 6 decades!).......but the encountered rendering issues will be a joy to deal with.....that is one technical-challenge part of it I enjoy over any arty stuff......tongue2.gif..........Dave.

 

Below is a mock-up of the sketching setup adapted from this Thread: https://www.cloudyni...-sketch-board/

This a photo-realistic sketch. I am impressed of the very different ways of sketching we have.

Honestly, it looks like a crop from an Apollo orbit photo!
