Sky - Watcher 200mm
Eye Piece 8mm TVP
Pencils Steadtler Softlead 8B & B
Winson & Newton Cartridge A5 Pad
Humidity 47%
Wind Calm
Temp 20 degrees
Seeing 3
I had only one opportunity to try out my new 8mm T V P eyepiece that was on July 1st when I sketched Mare Nectaris. I was keen to have another go but cloud etc and the waning moon left me longing for another chance.
As we are in the middle of a heat wave and the humidity has been half its usual wet self.
I decided to employ the Brain Clock method formerly used by Rich, and get up at an ungodly hour to gaze at our lovely Luna..
I heaved the Sky Watcher out at 03:00 UT the moon was stunning, Venus blazed away like a mini sun low in the North East, it was warm and still.
I scanned the terminator in search of an attractive target, so much on offer, a smorgasbord of treats. The darkness of the terminator was so so stark to the light sunlit moon; I saw what looked to me like a pair white eyes looking back at me from the blackness, two high points catching the sunlight in a black pool, and another shape that looked like a guy in a cap.
So of I went sketching away lots of dark shapes and drama, started sketching at 03:20 UT finished at 04:02 UT July 19 2006. Clavius and her craterlets were up above to the right (S is Up) and Rupes Recta was down below to the right so I think I sketched the area around Walter ?I was so carried away with the blackness I did not put enough into the lighter areas.
Got a bit sleepy then, said to myself I will ID this tomorrow, tomorrow came and VMA terminator is very grey not black, not defined and I found it very difficult to settle on what I had done in the early hours. So a failed sketch, because I should have made a positive ID on some little feature so I knew where I was.. So lesson learnt, choose targets when you are awake, only draw when you know what you are looking at and perhaps do not choose to draw because the shapes are great.

Excellent! I loved the whole observation report and you've got a great sketch to show for it too. Don't worry, we'll see if we can get this ID'd for you.
On the VMA program, make sure you have the date and time correct and press compute, and then go to 'Setup' on the right hand side of your screen. Make sure penumbra lighting is set all the way to the left, diffuse all the way to the right, and then adjust specular until you have the best contrast. That will help remove the gray and make the terminator darker and with more contrast.

Ok, from what I can see, it looks like you were observing in the Southern region. Does this look like the right location?

Thanks I have made the Setup adjustments and Clavius is indeed above to the right of the now blacker terminator but Rupes Recta is hiding in the darkness so I will have to study it all again.
Thanks

I see you had your image as maybe Walter. Walter would have been hidden in darkeness after July 17th, so it couldnt' have been that. My guess is it could be Wurzelbauer at the bottom and a hint of Heinsius at the top. Sometimes the lighting plays tricks on us and it can be a little difficult to ID your target without identifying key features around that area such as where was your target compared to Copernicus or Bullialdus?
Here is why I think it could be the two features I've named:

Hmm that's possible, the lower crater that you have the yellow arrow to had very defined black rays heading toward the terminator on a mid - grey background, it stuck in my head because, I noted the way it was but did not spend the time, have to take smaller chunks and pay more attention, I wonder what the two peeks of sunkissed luna were ? Thanks for trying to ID it .

The two bright areas could be any number of the parts of the ridge between Gauricus and Gauricus A.
The black rays that you refer to are most likely shadows of the ridges within Wurzelbauer.

Dee, I'm going to put a link to this thread in the Lunar forum so the rest of lunies can help out.

OK after looking at what you think Erix, that would give me the rim of Tycho at the top of the sketch just glinting in the sunlight. The peaked cap shape could come from the Wilhelm D Heinsius C, and Heinsius combo if they were filled with blackness.
That would give me Wurzelbauer below and Wurzelbauer M below right, possibly giving me Wurzelbauer opposite the perhaps sun kissed rims of *Word deleted by the CN gnaughties gnomes* C and *Word deleted by the CN gnaughties gnomes* A
It’s a bit like a who don’t it, we know who done it we just do not know what it is.. :-)

I see the word for my possible sunkissed craters has been cleaned up, its a very hot place that is allegedly , where some people go if they are bad in life.

Hi Dee! I got here from Erika's link (thanks Erika!).
Erika is correct, it cannot be Walter, and it is probably the area adjacent to Wurzelbauer. It's a little easier to see on Hatfield 9b than Rukl 65. From your description it seems you may have been on the very southern shore of M. Nubium.
A very difficult area to target, and you've made a nice sketch. Along with the usual data you recorded, here's a little trick I've used that might help you in the future. If there's no time to properly I.D. the target at the time, I make a map with my EP cap and point to the area as closely as I can with a little arrow. That, together with all the usual data (scope orientation, time, date, mag), lets me get to the right spot on the charts later.
Anyway, nice sketch. I haven't been in the sketching foum for a loooong time. Lots of great stuff going on around here!

Dee on the contrary, congratulations on a wonderfully successful sketch!  It's just my take, but I think you've caught the area between Wurzburger D at the very top of your sketch and the big craters Wilhelm and Montanari at the bottom. That interesting little "V" you drew to the right of Wurzburger D looks like Haidinger M. Heinsius, mostly cloaked in shadow, hides Heinsius A and T in darkness, but B,C and D are exposed in the bright sunlight. Below that Wilhelm O, M and Tycho Y. The whole sketch is very beautifully drawn and quite accurate. 
Dee, just remember not to wind that brain clock too tightly, I know I've broken a spring or two!

Hi Dee,
I can help on the ID part, but that's an excellent rendering.
The style is all your own, and I love your marks. That
drawing has so much spirit, unique and expressive!
Thanks,
Matt

Thanks Erica and Rich and everybody else who helped to ID my sketch, looking at it again this morning what is convincing me is the shape of Heinsius, the position of Wurzelbaurer D, the gap between Wurzelbaurer D and that V of Haidinger M.
Thanks for giving it your attention, and time, I will forever more take more care and ID something to flag my sketches as I do them no matter what time of the night it is.

Rich, Wurzburger D at the very top of your sketch and the big craters Wilhelm and Montanari at the bottom can't be true because that would put the orientation with North at the top and in Dee's view, South is at the top.
Dee, I'm still wondering how you were able to view Rupes Recta was down below to the right on the date and time posted. Could you have the date incorrect? At July 18th, at the 4am UT, with your positioning for Long and lat, Rupes Recta and Clavius would have been exactly where you described it. And have a look at this!!! It matches perfectly!
PURBACH is the crater with the yellow arrow. Lexell has the pink circle around it. The three pink dots at the top right of your sketch is actually Pictet E above Sasserides A. And both of those are to the right of a roundish slope that looks like a big crater, but isn't.
Soooo, could you have accidently put down the wrong date and it was the 18th at 3-4am?

Gosh Erica that's spooky, just as I was thinking it was solved this happens :-) and yes it is possible I wrote the wrong date, and I do remember Rupes Recta being below right at the time I sketched, but got confused looking a VMA next morning as I did indeed have some settings incorrect and have adjusted them since. Looking at what you have presented explains more features in my sketch .
It's amazing trying to fit the shapes in the previous scenario into my sketch, and I was thinking that my other sketches were accurate and I just could not get my head around this one , if you are right and it really looks like you are , then I was really daft with the date.
Looking closer and closer still
Thank You that is amazing

I couldn't believe the comparison between the last scenario compared to your sketch, either. It would make perfect sense and your sketch is very accurate to it.
A lot of times I make mistakes like the date and time on my observations and normally someone else catches it or I do after I've posted the reports. I used to get really embarrassed about it, but I've just resigned myself into the fact that I'm usually either in a hurry or very fatigued when I record that kind of data.  It happens to me especially when I'm converting to UT with the dates or am observing after midnight.
You're great with your observations and sketches, Dee. I'm looking forward to seeing more!

Oops  that's what I get for winding my brain clock too tightly! Sorry about the confusion!

Bingo Erika! The wrong date (or mis-calculating U.T. in the wee hours as I often do) would answer that nicely. Excellent work!
