Hi all,

tonight, the clouds vanished for some hours so I set up the Dobsonian on the terrace and did a lunar sketch again.

 

20170203_Rima_Hyginus_small.JPG

 

Telescope: Martini 10" f/5 Truss tube Dobsonian
Eyepiece: Skywatcher 5mm UWA 58°
Date & Time: Feb 3rd, 1800-1900 CET
Location: home terrace, Dusseldorf region, Germany
Technique: chalk and charcoal pens on black sketching paper
Size: 11"x11"
Literature: Craters of the Nearside Moon, Features of the Nearside Moon (both by John Moore)

Right in the center of the 200km Rima Hyginus, there's Hyginus itself which - as per Moore -- is assumed to be a volcanic caldera instead of an impact crater. Southwest of it there is the crater Hyginus A. Further to the west and south, Rimae Triesnecker lead to the crater Triesnecker whose northwestern rim wasn't illuminated yet.

Clear skies!

Achim

      So ... I've been playing peek a boo with the moon this morning as I found there was a possibility of it being visible in the  lovely bits of blue morning sky .... and it was... periodically But then found I had no idea what my camera settings ought to be for daylight shots once i'd got myself setup on my scope..😂
       
      Can someone give me some pointers? Pleasey 🤩
       
      I'm using Backyard nikon on my laptop
       
      EDIT
      OK I had a bit of (non moon ) blue sky to play with so I tried to work it out for myself.  The attached photo is of what I THINK is going to be getting something useful when/if the moon comes back  from its hiding place.. So the settings were Shutter 1/1600, Aperture f14, ISO 1600...  To my untrained eye that looks to be a reasonable starting place.. but 
      What do you think?
       
      Is this me being on the right track ?🤔
       
      I've saved these settings in the app to recall them next the moon pops up in daylight  (maybe tomoz)
       
      Would you believe there's a whole window full of blue sky -just where the moon isn't...  Where the moon is is just a white out of bulbous spoil sports..😤 - I bet you would believe it!🤣

      Hello
      A mosaïc of two pictures on Clavius.
      When the sky is cooperative we have a lot of fun. But it never lasts long.

      Just Rutherfurd alone because with its internal relief I find it very interesting.

      Clear skies.
