Aloha!

This was one of those nights things just fall together. Excellent seeing and light enough from the Moon that I could see the paper well. After finishing my sketch at the eyepiece I went inside to clean it up and was pleasantly surprised that I liked it pretty much the way it was.

110km wide Gassendi Crater showed some excellent roughened floor details with hummocks casting shadows as well as floor rilles illuminated as bright & dark lines. Rima Mersenius is brilliantly lit on the terminator and the bright scarp of Rupes Liebig can be seen at the base of the wall.

Surprise Libration

The lunar crater Gauss and environs seen in different librations on January 16, 2014 and December 8, 2014
The lunar crater Gauss and environs seen in different librations on January 16, 2014 and December 8, 2014

Last night I made a sketch of Lunar crater Gauss and its surroundings. While archiving the sketch this morning I realised I already sketched this part of the Moon almost a year ago, so I got the idea of a side by side comparison to show the effect of lunation. To my surprise I found out these sketches were made at the exact same lunation: 15.5 days. The difference in lighting therefore had to be caused mainly by the Moon’s libration; the slow wobbling of the Moon in its orbit. A pleasant suprise to find out I sketched this phenomenon totally unintentionally!

Both sketches were made using a 3″ Polarex Unitron refractor at 171x, with a white pastel pencil on black paper. Orientation and size were matched using Photoshop.

H-alpha Solar Observation

A solar observation including prominences, a large active region with sunspots and filaments - October 26, 2014
An H-alpha solar observation including prominences, a large active region with sunspots and filaments – October 26, 2014

Aloha!

This week has been fascinating observing the giant sunspot region 2192 making its way across the solar disc. I was working today to demonstrate the details of the intricate swirls of magnetic activity around the sunspot and filament regions. I utilized the Tilting Sun graphic again for this observation though it is reversed from a standard view to demonstrate my view through the eyepiece.

Pastel on Black Paper, white pencil for the stars

Conditions on December 26th, 2011 made it so that my friend Mat and I went observing for the night in the West Desert of Utah. Conditions were clear, cold, about 15 degrees F at the time. While we were setting up there was a wonderful Sun Dog in the Western Sky which we took as a good omen and sure enough, we had a wonderful evening. I would rate the sky at an Antoniadi II this night when I sketched this object. I used my Orion XX14i, a 14 inch truss dob, a 27mm Panoptic as a finder and a 10mm Pentax XW to sketch the object. This galaxy has a very stellar nucleus with a bright inner core that is surrounded by diffusion. Nice star to the west of the galaxy and the southwest end of the galaxy tappers and thus had more detail located there. Not a particularly well known or observed galaxy, but one in the Eridanus cluster and worthy of a look if one is there. Who says winter isn’t galaxy season?

Seeing: Wilson 4.7-4, Transparency: 4/6, 50x, Alt: 72.7, Az: 175.3

Sketch created at the eyepiece with black Strathmore Artagain paper, white Conte’ pencil and crayon, and white color pencil.

NOAA 11543 had very bright plage. The sunspots within it weren’t quite as pronounced as the other day. There was a very large filament going east to west in the SE quadrant of the solar disk. More plage located to the SW and the E-NE quadrants.

The brightest, largest prominence that I spotted was located on the NW limb and resembled two dancers joined by their outreached hands with their other hands stretched out behind them. More prominences were scattered about the limb, but to the SW, a very short, bright set of prominences were apparent.

Hello friends artists,
this is my sketch of the Panstarrs, one of the comet of 2013. The tail of the comet was long enough and the head was very light. This is my first comet and I liked it so much. I observed it with a 100 mm telescope, at 7,30 p.m. It was visible with naked eye like a 2 magnitude star. Moreover I observed it with a 20×80 binocular, and it appeared equal, more or less.

Hope you like this sketch! And I hope you understand my english!

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.

Partial Annular Eclipse

H-Alpha Eclipse Diagram - May 20, 2012

Knowing that we fell within a good band to view a partial portion of the annular eclipse, Paul and I scoped out the local county roads earlier in the day for optimal horizons. The partial eclipse for our location was due to start at 1932 ST (0032 UT) which would only give about 50 minutes of eclipse viewing before sunset. The skies cleared up and we were fortunate to have perfect viewing conditions that evening.

I started off drawing the full solar disk in h-alpha. Four active regions lined up east to west with two more to the south (depicted to the top of the first sketch in the animation). I then made a quick second sketch to use for recording the times and placements of the Moon as it passed between Earth and the Sun.

First contact was at 0032 UT. The first marking was at 0035 UT. I set my iPhone’s timer to go off every five minutes until sunset, marking the Moon’s progress each increment with my oil pencil along with the times. In between, Paul and I would alternate using a pair of solar glasses from solarastronomy.org and the views from my double-stacked Coronado Maxscope 60mm h-alpha telescope.

The first image of the animation shows the original sketch in its entirety. Later, I used the second solar disk sketch as a reference to recreate the eclipse on the original sketch with a cut out circular piece of black Strathmore paper. This animation is the result.

As the solar disk became too dim to view (represented in the last couple frames of the animation), I was forced to leave the eyepiece and enjoy the last several minutes with the solar glasses and my camera.

Two original sketches created at the eyepiece with black Strathmore Artagain paper, white Conte’ crayon and pencil, white Prang color pencil, Derwent charcoal pencil, black oil pencil.

Link to gallery of individual sketches within the sequence.

During the time I observed, a very large prominence off the northeast limb was enlarging and in the process of ejecting as it broke free from the magnetic fields supporting it. I’ve never visually witnessed that large of a prominence breaking away from the Sun before. What really stunned me was how bright it remained over several hours that far off the limb. I grabbed an 8-sketch sequence spanning over 6 hours of the event, not including the full disk rendering I recorded earlier in the day. The last 35 minutes of my session, the prominence became very faint and diffuse. I stopped seeing any connection from the limb after 1717 UT. Of course, that doesn’t necessarily mean there wasn’t, but was perhaps too faint for my tired eyes to see.

Object Name: NGC4038 and NGC4039
Object Type: The Antennae Galaxies (Corvus)
Location: Roque de Los Muchachos, La Palma
Date: 30. June 2011, 11:50 PM
Media: Chalk pencil on black paper
Observer: Christian Rausch
Telescope: 12inch/F5 Dobson (Hofheim Instruments)

Conditions:
– SQML = 21,65 mag/arcsec*2, seeing ok, Temp. +12C
– 165x (Nagler 9mm)

The Roque de los Muchachos is one of the best places to observe the night sky and main base of the European Northern Observatory.

It was impressive experience to spend the night on the top of the 2450m high Volcano and in between observatories like Galileo Galilel, William Herschel, Isaac Newton or the GTC.
