Moon/Jupiter Appulse sequence
Posted 22 January 2013 - 06:14 PM
I was fortunate to have clear skies with a decent temp of 40-45 F for viewing the appulse between Jupiter and the Moon.
The full report is here or you can see the CN link in the observing forum here.
All sketches were done at the eyepiece and then flipped horizontally for better comparison to a naked eye view. The sketches created with black Strathmore Artagain paper, white Conté pastel pencil and color pencil, black color pencil. I changed to monochrome in Photoshop because the photos of the sketches gave them a bluish hue that I didn't care for.

I'm really glad you had the conditions to follow the appulse. Way to cold and windy here--I took a few pics (one is posted in the General Observing forum) and then retreated indoors.

Very, very fine sketching. I stepped outside for 90 seconds to have a quick look but - 17 degrees C is too coooold for me to sketch. I am happy you did this. It makes a great animated sequence that I just looked at over at Chuck Wood's site LPOD. It will be there all day Wednesday for those that want to see it.

Anyhoo, your lunar sketches are as good as any I've ever seen. Truly remarkable illustrations, here. And you've captured the beauty of Jupiter the way I see it through my 15x85 binos. Congrats on being targeted for LPOD.

What a great and lovely sequence of sketches! And you sketch the moon from scratch on each sketch? You have my admiration for that! Outstanding reproducibility.
Here in Montreal, it was so darn cold (-20°C)that I did not even have the guts to take a photo!

Jean, yes, they are all from scratch at the eyepiece. As you can see, Mare Crisium wobbles up and down between the sketches. I used an eyepiece cap to trace around and then filled it in with Conte' and blended. The next step was to plot Jupiter, its moons and the star field, followed by filling in the details of the lunar surface. By that time, it was nearly time to begin the next sketch. I had about a 10 minute break in between sketches.
Normally, I plot stars near the edge of the drawing field first so that I don't run into position problems. I failed to do that with this series, which resulted in me having to include stars outside of my drawing field (that were in reality within my FOV) in their correct positions relative to the other stars. I was pretty disappointed in myself with that but it was a learning experience.

I joined the others to let you you it's a very interesting sequence. Beautiful.
