During the early part of the current lunation I was observing and sketching in Mesa, Arizona and caught the thin crescent Moon in the southwestern sky just after sunset. Venus was also visible much closer to the horizon but not close enough to the Moon to be included. Earthshine improved and brightened as the hour passed.
For this sketch I used dark blue sketching paper (8.5” x 11”), white, yellow and brown pastel pencils, blending stumps, white Pearl eraser.
Telescope 6”f/7.2 Dobsonian telescope, 28mm eyepiece 39x
Date and Time: 12-23-2014; 18:15 – 19:10 local time
Seeing: Antoniadi III
Transparency: clear 4/5
Temperature: 18 °C (65°F)
Lunation: 1.74 days
While observing our ever changing Sun today I was struck by a grouping of prominences on the western limb. All of them of high intensity and curving towards the same direction. They made me think of the story of Goldilocks & The 3 Bears!

Object Name Sun
Object Type Sunspot 1575 and crown
Location Néoules Provence France
Date 22 sept. 2012 – 13h TU
Media (graphite pencil for the spot, red pastel for the crown, two different white papers, Paint.net)
I made two separate sketches, one in H alpha via a classic PST for the crown, the second one through a 1000/102 refractor with solar continuum filter for the spot.
I used several eyepeaces.
The compilation was done with the freeware software : Paint.Net
Conditions were perfect, the sun was hot here… !
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.
At the last day of October I sketched a beautiful conjunction between the Moon, Jupiter and Aldebaran. The building in the foreground was my holiday-resort (illuminated by a streetlight), a renovated farm from 1669. By chance: in the first months of 1669 Jupiter was also next to Aldebaran in the sky. So the first inhabitants could have witnessed a similar conjunction. To add some more history: the location was less than 10 km from Middelburg, the town where the telescope was invented!

Object Type (open cluster)
Location ( iran,dergajen, 35.058548°N, 51.420321°E)

Explanation:The first step is enhancing the contrast then increasing the brightness. Making the image black & white requires going to image menu, select adjusments and clicking on the Black&White button. Finally I’m going to add a little sharpness to the image by selecting Sharpen button from the Filter menu.
When we sketch the sun, we sketch sunspots or H-alpha. But the most beautiful thing to sketch is a sunrise or sunset. During my 2 weeks holiday in France I observed every day the sky just after sunset. I missed only one day due to rain.
The sky and the trees were sketched with a set of 12 soft pastels. The farm was sketched with pastel pencils. The original drawings are all A4-format. I waited the sun to set behind the trees and started sketching as fast as I could. After 30 minutes I stopped because the sky changes very fast.
I had great difficulty in sketching the trees. The dark green pastel was to light, the black and brown to dark… The second week the result is much better than the first week.
