Jupiter and Saturn April 6/7 new
      #5784184 - 04/07/13 04:08 PM Attachment (54 downloads)

Here's a couple of sketches of Jupiter and Saturn from last night, with decent seeing (about III). I observed Jupiter with the 10" Clark refractor at Bethany (CT), 335x,08:35pm Eastern Time; Saturn from my front yard in New Haven a few hours later, Newton 10" f/7, 300x, 04:25am. Still without AR drive so it was a bit tricky.

These are the sketches I made right at the telescope, at times I like to leave them "raw". The dark spot is Ganymede's shadow.

Clear skies,

Ivano

Ivano,
Beautiful work. The Clark must provide great views.

Ivano,

Two truly excellent captures of these gas giants.
The Clark scope gives a fine look at Jupiter based on your sketch.

Well, as a matter of fact optics would need a good check up... Contrast is not as good as it could be, so it takes some attention to pull out the details. Seeing makes a lot of a difference, it is truly great when it's good.

hi all,

Ivano:
great sketches !

The Saturn stencil is interesting, because the background is white too.
Do You draw it at homework or can I find it via www. ?
Are there several variations for the changing pol tilt ?

Bye
Christian

I love the raw Jupiter sketch, I sometimes prefer my raw pencil sketches to the final colour versions...oh well!

Christian, Google Saturn Viewer. you can enter any observation date and fov you want and then print a diagram of Saturn.

Hi Christian,

I use templates from the website of the Italian Astronomical Union: http://pianeti.uai.it/index.php/Convenzioni_per_le_osservazioni_visuali. Scroll down until you arrive at Saturn, click to download the template with the right tilt. The page is in Italian but should be easy.

Most templates are for negative tilts, these years I just turn the sheet when I draw. Not a big deal when you digitize everything anyway. A white background is good to render the C ring, satellites or whatever lies outside the ball and the main rings.

You sketched lots of interesting details at both planets.
