Moon 12 August 2019 - Gassendi

Recommended Posts

Yesterday the Moon was  low in the sky (in Scorpius), but he seeing was good and allowed magnifications up to  257x.  Gassendi was the most prominent crater on the terminator. Here's a painting of the scene.

The small Moon image (Stellarium) shows the location of Gassendi.


Thank you for watching.

Very nice sketch! The red dot on the terminator is a move I haven't seen before, very illustrative! Something I will try to remember when sketching my first sunspot, believe it, that time will come 😉

Lovely sketch. Im just getting into sketching. Lovely to take the time to look and study.

What black paper and white pencils do you use ?
How do you get enough light to sketch without affecting night vision ?

Thanks people, for for your kind comments.

Hi Fraunhoffer, I make these on my computer with a wacom tablet, Corel Painter and Photoshop. I work from notes and partial sketches that have the details of the features I could see. From them, with the help of a reference, I make an underpainting in Corel Painter on the computer. Then with smearing and scratchy brushes, using pencil, oil paint, acrylic and charcoal (all mixed, whatever works) I make the painting. As I go along I compare the miniature version in the navigator window to the reference. Whenever I go seriously wrong I use undo.

Only the larger features in the result are realistic, but that's OK. I feel a sketch should be a personal interpretation and that's what I aim for. Photo realism is for the imagers. The observation takes half an hour or so, the work on the computer takes several more, but it's a nice thing to do. I listen to the radio and a podcast or two while I'm at it.

We also have real pencil and charcoal sketchers here and I hope they can provide you with a tip or two. My suggestion would be to draw a rough overview of the scene and several partial sketches at the telescope. After that I'd do the final sketch indoors with good light, sitting at a comfortable desk.

Think this nails it. The interpreting can vary, big scale realism. For me starting out with pencil sketching it's about not having too big expectations, it'll come to you. Good enough whatever it is, as long as trying to develop at some level.

      I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence.
      The telescope is out - of course - and I managed a session before dinner.
      I thought about sharing some photos taken with my phone and a couple of sketches.

      Hello stargazers, welcome. I had posted a picture yesterday of Uranus that had appeared to show its rings. I am using a Nexstar 4se, a 2x Barlow, and my Neximage Burst Color and capturing hundreds of photos and stacking them for my results. But still had me and others curious to if I were actually seeing the rings of Uranus or maybe just a glare of some sort.
      So I got back out there this morning, might I note I live in FL where the weather tends to stay hot so clear imaging during this time of year can be difficult, but not impossible as this image that I stacked 150 out of 300 images taken may show that statement holds true..............or I could just be mistaken the object in the image, but all in all I am feeling pretty confident that I have a decently clear image(stacked 150 images) of Uranus, its rings, and one of it's distant moons. It may be necessary to zoom in on my photo in order to see the moon it should be down and to the right of the planet a good distance in relation to the size of planet, I noticed that looking at Uranus in the photo helped bring the moon out just like stargazing in real-time. 
      If anyone can better distinguish what I might have done right or wrong here any help would be appreciated (also forgot to change format save for my images so I am stuck with .bmp and setting it as a download, sorry for any inconvenience.) - - - J47(JAY)

      Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. 
      Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. 
      Besf regards to everybody

      Hello Astronomers,
      On the 12th August, between 18:34 and 19:21 we had a occultation of Saturn by the moon.
      Of course I couldn't miss out of such a event so I took the day of work and setup my gear so that I could simultaneously capture the event as well as observe it.
      I had the SCT recording with the 618C while observing it in the dob... literally at high power it looked like a Saturn rise... massive lunar horizon filling the field of view with a big Saturn rising from under it, literally animated and visible slowly moving up... Looked amazing in the eyepiece... 
      Photos or videos don't even come close to how good that looks live in the ep.
      I had my eye on the eyepiece in the 14" Skywatcher during the occultation and recorded the start and finish times as soon as I noticed them:
      Occultation Start 18:35.51 AEST
      Reappearance Start: 19:19.37 AEST
      Occultation Finish: 19:21.20 AEST
      I stuffed up the first part video, the covering of Saturn because I still had iCap set to capturing a maximum of 5000 frames left from my planetary imaging, so at 25fps I barely got a 3.5 minute video that stopped just before the actual occultation started... yes I was kicking my self... but at least I watched it... I wasn't going to do the same mistake on the re appearance on the other side...
      Sharing with you my photos and the video of the event... video is sped up to 400%.
      Clear Skies.

      9 August was a good night for the Moon, so I studied the region from Ptolemaeus to Arzachel at 231x. Especially Alpertragius stood out, with its oversized central mound. It has been suggested that this is a volcanic feature. Herschel too was quite prominent.

      Thanks for watching.
