Moon, 2 days past full July 20th 2008 Midnight ~ 2 AM, observed through Nexstar 5i with 32mm Plossl and 12mm Plossl for close-up inset image in detail.
*Sky clear, calm; seeing estimated as 9/10.
*Temperature 63 deg F dropping to 58 with dew point rising fast.
Observed through a Nexstar 5i at low and medium magnification, my original intention was to render this sketch as the whole moon.
Canson Mi Tientes medium tooth Blue Indigo paper of 20” X 24”.
Old antique pastel chalk sticks in square sticks and round include Sargeant, Grumbacher, Eagle Prismapastel, and various carbon greys as Swan Stbilo CarbOthello brand; I have purchased a few new ones as small square sticks. These are NuPastel. I have never used a blending stick. Only cotton swabs, Q-Tips and occasionally my bare fingers although I abstain from that as I know that it destroys the paper surface. I have never used a fixative on any of my works so they are vulnerable to smearing, thus kept stored until determination of whot to do with them in many requested prints now. Occasionally but not too often I accidentally smear some chalk in the void blank areas. I will lightly clean off or erase those areas with a dampened cotton swab before photographing the work with a 5.1 megapixel Sony Cybershot under north daylight or photoflash at night. If exposure is insufficient, I will drop brightness in Photoshop by a fer points and raise the contrast an equal amount. Color balancing is done with the camera settings per the ambient light- True north UV daylight or photoflash.
This was the first time I also used new chalk pencils by Faber Castell in snow white and a Swan Stabilo in cream white.
Much of the color on the whole moon was left as unblended with the exception of some small portions as you can see. That image is to be somewhat impressionistic yet I have rendered the actual craters and maria as accurate in position and placement as I could in under 2 hours (25 ~ 30 minutes of that time was spent on the close-up inset detail which actually became the final work for this forum.) Finally my left hand was omitted from the lower potion of the work with Photoshop erasure so as to not clutter the subject matter, hence the vignetting in the lower edges of the blank blue indigo paper.

...here is my submission of the King of the Planets, Jupiter
Posted 10 October 2008 - 06:22 AM
I would hope to see others lunar sketches in the monthly contest so perhaps this may inspire. It is the largest work that I have attempted as free-hand of the moon yet. Thanks to seeing Rich Handy's tutorials. This is on a fine textured Strathmore paper in Stygian Black in 19" X 25" that I found to be flawed with vertically parallel embossed lines through it after I began the work.
The moons disc was created with a home-made extended string fashioned compass and chalk pencil from another small compass hinge pin. The lunar disc is drawn at 14" diameter. The size did not allow to finish details on the first night in early September 2008 (moon date at 8.5 days), so I continued the central maria regions on the second night at 9.5 days, but left the terminator untouched. While finishing the details on the second night, I added the quick close-up sketch of Mare Imbrium on 9" X 12" Artagain paper if only to represent the feature of the fading light at the terminator edge at bottom. Some surface details in the mare area were left out or omitted due to time allowance. Pastels included new Rembrandt, antique Sargeants, and Prismacolor in various white and off-white, Swan Stabillo antique chalks in various greys. Faber Castell white chalk pencil. Minimal blending was done with cotton swabs.
*The two pastel sketched images were photographed with a digital camera under natural daylight, then sized and joined as a single theme and effort with use of Photoshop for online display here.
Observed through a 10.1" f/4.5 Coulter Dobsonian with a 32mm eyepiece. Seeing was considerably good at approximately 8 ~ 9/10. Temp 60 deg F, dropping to 57 F with still air on both nights.

The November 30th 2008 Great Conjunction. The scene so talked about at the beginning of December 2008 which became the most photographed lunar planetary conjunction in in photographic history. As I drove through evening fog heading west in east Portland Oregon, I witnessed a scene of the new crescent moon setting in the western sky with Jupiter and Venus above. I raced home to grab my portable Nexstar 5i and to a hilltop where I could observe the moon above the fog to render the surface details at the terminator. The street scene was added later at home from the memory of driving.
Sketched on Strathmore 19" X 25" Artagain Paper with various pastel chalks.

Moonrise with Saturn - Pastel Sketch on 19" X 25" format-
Tuesday night January 13th in very still air at 33 degrees F, yet poor seeing conditions, I decided to observe the moons spectacular terminator line with my 10.1" f/4.5 Newtonian and render this impressionistic and somewhat accurate pastel of the moons terminator line and as it was low and ‘warmed in color’ by the atmosphere. A 32mm Plossl was used for the general whole moon and a 12mm and 9.7mm for medium close-up details although the bad seeing (5/10 ?)did not allow much magnification.
A spectacular phase it was! I spent about an hour from Jan 13th 11:45 PM PDT till 1 AM Jan 14th roughing in the terminator and other key details, then retreated to indoors with use of a several digital photos I took through the eyepiece with a 9.7mm Plossl for close-up and 32mm for wide field for reference to recheck positions of and fill in the mare and other general surface features.
As Saturn was a few degrees above left of the moon I decided to add it in here, albeit a little out of distance scale from the moon yet showing the poor seeing conditions, I could barely make out Titan to the planets left, it is to accurate scale in apparent size to the live observation of the moon with a 32mm plossl at low power.
The paper was not what I would have preferred, a 19" X 25" Strathmore in rich blue with embossed ridge, my last available sheet. An undesired ridge-line shows through the surface. The moon was sketched at 15 inches diameter with various pastel chalks and mostly kept in the warm golden range of colors due to the appearance of it rising low in the atmosphere. I photographed the pastel image today in daylight for accurate pastel color representation.

This was done entirely at the eyepiece. The collage was put together in Photoshop after photographing my sketch (rather than scanning).

Solar prominences in h-alpha, western limb
PCW Memorial Observatory, Zanesville, Ohio USA
DS 60mm Maxscope, LXD75, 21-7mm Zhumell
Sketch created scopeside with black Strathmore Artagain paper, white Conte’ crayon and pencil, white Prang watercolor pencil.
Temp: 3° C, Humidity 60%
Seeing: Wilson 3, Transparency: poor
Scattered, winds 7mph from NNW
Alt: 34.4, Az: 159.2
Approximately 30° inward from the eastern limb, a crescent-shaped plage was seen with a dark dot during my h-alpha observation. No AR was noted in white light. There were a few proms scattered about to the north and south, but the prominences on the western limb really stood out. At first glance it looked like two detached proms, but adjusting the outer etalon and increasing magnification, that section of limb came alive with prominence structure.

I observed the moon with the public on ISAN April 4 and 5 2009 with use of a Nexstar 5i. I returned home for solitary observation through my 10.1" Newtonian; 32mm Plossl and 9.7mm Super Plossl eyepieces with medium ~ good seeing conditions; light breeze at 51 degrees F, from 6 UT ~ 8 UT April 5 to produce this large 22" X 30" multiple pastel impression on black Stonehenge paper with various off-white, blue and grey dry pastel chalks. Several areas of the terminator and surface areas were rendered in detail with medium high magnification at 180X; finally adding the artists conception from the surface of the moon at bottom. -Mark

For the last 2 nights I have made some deep sky sketches with my home build 60 mm F/6,9 achromatic refractor. It's made out of a 20-year-old Novalux 60/415 lens and some spare parts from various other scopes. The chromatic abberation is horrific om Moon and planets, but this tiny telescopes does give me surprisingly pleasant views of some of the brighter deep sky objects. It made me so enthousiastic I want to sketch evering I see through it! I also have a 12,5" Dobsonian but sometimes, when time is short and weather is unpredictable, bigger is not always better!
All sketches are made under a suburban sky. M8 was only 15 degrees above the southern horizon when I made the drawing.

M52 and NGC7635 (the bubble nebula region) in Cassiopea.
Sketched with graphite pencil on white paper.
Location and conditions: Negev Desert in Israel, ~6.3m sky, mediocre seeing.
Instrument: Orion Skyview Pro EQ Newtonian, Sirius Plossl 25mm Eyepiece, with Orion Ultrablock filter. 40x magnification, at 1.25 degrees FOV.
Date and time: 23.05.2009, 04:00
M52: Open cluster, 7.3m
NGC7625: emission nebula ("The Bubble Nebula"), 10m
Notes: Only the brightest part of the "bubble" was visble. However in one FOV with the M52 open cluster it forms quite a nice view.

Well, due to weather, I guess I'll have to go with a recent seasonal image from the not so far past again.
This was the largest pastel of the near full moon I have produced as yet. It was done over two nights for a total work time of approximately 4 1/2 hours through the eyepiece of my 10.1 inch Newtonain last July 8 ~ 9, 2009. It was sketched onto 22" X 30" black Stonehenge 100% cold pressed cotton pastel paper. The moons disc was rendered at 16 inches in diameter.

Crater Maurolycus was an excellent object to sketch with a small refractor. I worked on a grater scale than I'm used to (20x20cm). It makes it more easy to put small features on paper. But on the other side, it makes it more difficult to keep on eye on the total sketch. So are the small craters (in crater Maurolycus) drawn to small and not allways on the right possition. The smallest of the craters is only 6 km big! I thinks that's not bad for a small telescope (7cm). This is my most beautiful moonsketch yet.

I made a sketch of the nice solitairy crater Hercules (69km wide). I used my old 4" Polarex Unitron for this sketch. Magnification was 300x (5mm Plossl).
This is the raw sketch, made behind the eyepiece. HB Pencil on white paper. Original size of the sketch is 4" by 2".

On November the 16th, the mag.5 star 19 PSC was occulted by the Moon from the Netherlands. I've made a sketch of the Moon in the hour before the occultation. A few minutes before the star was obscured by the Moon I drew the tiny dot in place. Actually the star looked a bit "smaller" through the eyepiece, but I found it pretty difficult to render the brightness and keep the dot small at the same time. Never thougt a star would be more difficult to sketch than a full disk Moon! The orange color however, is pretty accurate.
