Clavius Crater

Hello friends artists,how are you? I sent you my last sketch of Moon
after some days of fog and humidity,the sky was opaque.
After this days ,finally,the sky was clear on zenit,some little light
fog on the horizon.I take my “old”refractor Kenko 80 1000 and with
surprise,i see the Moon very steady,incredible,the seeing perfect
and,thanks of this situation,i made the sketch of great crater
Clavius.Incredible the little particulars that i see….one thanks also
to my refractor,perfect for this observation.
I hope like you.
Ciao,Giorgio.

Monster Prominence

Solar Prominence - July 27, 2012
Solar Prominence - July 27, 2012

Object Name: Prominence
Object Type: Large plasma eruption on the solar surface
Location: Deventer, The Netherlands
Date: July 27, 2012
Media: White pastel pencil on black paper

This morning I aimed my 70mm solar telescope at the sun and I almost got blown away by what I saw. I GIANT prominence on the north eastern limb. I hovered above the surface like a huge dragon. I made a sketch with white pastels on black paper, color added and orientation-flip with Photoshop.

Clear skies!

Mercury Transit – 1970

Mercury Transit
Mercury Transit

Hey Artists!

As the time of the “last” transit of Venus is perhaps ended, I would like to show all an old
but spectacular observation of a transit of Mercury I made in 1970.
My sketch shows not only a solartransit, but the planet also passed over a close bipolar
sunspots!!
It was interesting to observ the absolute black Mercury with the umbra in the spots.
The umbra was easy seen brighter. My info on sketch is in norwegian!
This was a lucky observation, indeed!!
Location : Trondheim, Norway.
I used pen and pencil on this original sketch.

Thanks for nice comments on my sketches!!
Have a clear sky and nice time to all!

The Sun of november the 7th

H-Alpha Sun - November 7, 2012
H-Alpha Sun - November 7, 2012

Object Name (Sun)
Object Type (H alpha regio…)
Location (Rocbaron in Provence – France)
Date (2012 Nov 7th)
Media (graphite pencil for the prominences, pastel on white paper for the solar texture, Paint.net as digital tool)
Scope My new Lunt LS35THa/B600 on motorized EQ3 mount with 10mm eyepiece.

I made a pastel texture on CàGrain Canson white paper to imitate the solar surface, and I sketched the proeminences on another paper with graphite pencil. Then I combine both digitalized sketches via Paint.net respecting the 3 bright areas. I cheat a little bit regarding the color pushing my sketch to orange which is maybe more convenient for the contrasts.

Clear sky to you all !

Craters Lansberg and Reinhold

Craters Lansberg and Reinhold
Craters Lansberg and Reinhold

Both of these craters look similar when their floors are in shadow as was the case when I viewed them. Lansberg (40 km) is a walled plain crater sitting where Mare Insularum meets south Imbrium. This old impact dates back to the Upper Imbrian and is near the center of my sketch. Reinhold (49 km) is a prominent lunar impact crater of the Eratosthenian period and is also on Mare Insularum. It is below Lansberg near the bottom center of the sketch which by direction is north as per the inverted Newtonian telescope view. At the top of the sketch (south) I was able to catch the Riphaeus Mountains receiving first light during this waxing gibbous phase.

Sketching:

For this sketch I used: black Canson paper 9″x 10″, white and black Conte’ pastel pencils and blending stumps. Sketch was scanned
