<p>Our daughter set her alarm for 5:30 am to catch the eclipse this morning, and we awoke to the sounds of her crashing into things in the dark house. So, we all got up, threw on our heavy jackets, and drove away from the moon-blocking mass of Mt. Elden. We watched the moon slip into shadow as dawn gradually hid it from view. The belt of venus solidified along the western horizon to top off a beautiful eclipse.</p>]]>

        <![CDATA[<p>If you've been keeping up with <i>Astronomy Now</i> over the last few months, you've probably noticed that Peter Grego contributed two articles on sketching techniques for Jupiter and its moons. And now in the new December issue you will find an article by Erika Rix on lunar crater sketching.</p>

<p>I'm excited that they have both joined in to add their expertise to these and future articles. They will bring some great, new perspectives to the column, and a much appreciated raising of the bar on techniques for planetary, lunar and solar sketching. I hope you enjoy and learn from their contributions as much as I do!</p>

<p>If you haven't subscribed or picked up a copy of <i>Astronomy Now</i> before, they have made a free copy of the January 2011 issue available for download here: <a href="http://www.astronomynow.com/magazine.shtml" target="_blank"><i>Astronomy Now Online</i></a> (Click the link in the right column that says "Free PDF")  Be sure to check it out!</p>

<p><b>Observation Notes:</b><br /></p>
<p>I enjoyed a very nice view of C/2009 P1 (Garradd) tonight. It's been too long since I've gotten out for a recreational observation. The coma was moderately condensed with distinct elongation to the southeast. Further scrutiny revealed a prominent tail about 10 arc seconds in length pointed to the southeast at a PA of 115&deg;. The south edge of this tail had a more abrupt spine while the north edge was softer. At a northeast PA 67&deg;, a shorter, more delicate tail drifted about 5 arc seconds from the central condensation. Overall, there was an impression of a diffuse hood draped across the northwest side of the coma.</p>

<p>At times, I thought I detected the slightest hint of green in the coma, but I wasn't certain enough to include it in the sketch. The warmly colored, ninth magnitude glow of TYC1559-1174-1 decorated the north edge of the view. I looked for evidence of the comet's motion 90 minutes later, and there appeared to be some slight drift to the northwest. However, I hadn't plotted the star field with enough density close to the coma to estimate the apparently slow motion with enough accuracy. </p>

<p><b>OCT 31, 2011 UPDATE:</b> I re-observed the comet the following night (NOV 1, 2011, 0330 UT) and noted motion of about 8 arc minutes to the west-northwest at a PA of about 287&deg;.</p>

<p><b>Observation Notes:</b></p> 
<p>Iota Leonis was ridiculously difficult in poor seeing--only resolving for moments as a dim fuzzball that was fainter than the primary's flickering diffraction pattern. They both appeared colorless. Smyth saw pale yellow and light blue while Hartung saw deep yellow and whitish.</p>

<p><b>Observation Notes:</b></p> 
<p>AG 342 is an orange-yellow/dull-orange pair, located at the thruster end of a star-destroyer asterism. The diffraction pattern was faint and difficult to pin down. This is a high proper motion pair (190 mas/yr) of K3V stars.</p>

<p>The excellent sketch of the Eta Carina Nebula Complex above was created by Alexander Massey, of Sydney, Australia, using Scott Mellish&#8217;s technique. The stunning host of nebulae were observed with a 17.5-inch f/4.5 Dobsonian, 35 mm Masuyama eyepiece at 57X, and OIII filter. Alexander met with Scott in late 2010, where they discussed the techniques that allowed Alexander to prepare the detailed tutorial found at <a href="www.iceinspace.com.au/63-614-0-0-1-0.html" target="_blank">www.iceinspace.com.au/63-614-0-0-1-0.html</a>. </p>

<p>The highly detailed sketch above was contributed by Erika Rix of Ohio, USA. The full disc H-Alpha sketch was prepared scopeside using black Strathmore Artagain paper, white Conte&#8217; crayon and pencil, Derwent charcoal pencil, and black oil pencil. One of the benefits of sketching white on black is that the entire image is displayed in positive format. Erika also notes that the black stock is much easier on the eyes when switching between eyepiece and sketch. More of Erika&#8217;s sketches, and discussion of her sketching techniques can be found at <a href="http://pcwobservatory.com" target="_blank">http://pcwobservatory.com</a>.</p>]]>

<p>The above sketch by Chris Nuttall was included in the article as an example of a sketch created in color with traditional media. Chris describes his sketching method and includes observing notes below:</p>

<p><b>Drawing method</b></p>
<p>The drawing was originally done as a very faint hb pencil sketch on white velour paper.
Next I carefully added the grooved look to the B ring again using an hb pencil, taking care to leave the edge bright white. Then the A ring was shaded using a blunt 2b pencil, and the C ring was shaded usind a 4b pencil. The A ring was smoothed with a paper blending stump, and the B ring was shaded slighly blue with a conte pencil (because I haven't yet bought a pale blue pastel pencil!). The dark detail on the left side of the B ring was added last with a 2b pencil.</p>

<p>The disc was then shaded using pastel pencils, I have a variety of different makes in my collection. A broad background tone was laid down using a cream and a pale yellow to achieve the correct hue, except for the storm area as I wanted this to have a white background. The Southern hemishpere was darkened with greys and a little blue.
The NEB was coloured brown over the yellow base, and then terracotta was added in three different strengths to make it warmer. I took care to make the centre of the belt richer and darker than the edges, which were also left slightly uneven. The SPR was darkended using browns and greys. Achieving the right look in the storm zone was simply a case of shading using a couple of different greys and letting the white paper show through in the correct places.</p>

<p>The limb darkening was added using three shades of grey pastel pencil, and smoothed using a scrap of velour paper. Finally the image was cut out using a scalpel and mounted on black heavy weight paper using a spray adhesive.</p>

 
 
<p><b>Observing Notes:</b></p>
<p>The drawing of Saturn was made at 23:30 on the 18th March 2011.</p>

<p>It was the first time I have used my Binoviewer, a Baader Maxbright, with a Multimag OCA by Harry Siebert giving me x1.25, x2, or x3.5. The only pair of eyepieces I have is two 15mm Japanese Meade 5-element Plossls. Based on this observation I am going to buy more pairs as I am a bino-convert!</p>

<p>Seeing started at AntII, but became AntIII around midnight. I am getting over the 'Flu and I was pretty tired, my mirrors desperately need cleaning, but despite all this I had one of my best views of Saturn in a decade of Observing it, up in the top 5% I would say, simply because of the ease and comfort delivered by using two eyes. The image with one eye through the bino was slightly dimmer than normal but with both eyes it was just gorgeous, I quite literally stared and stared with my mouth hanging open for nearly two hours! Saturn truly looked 3D and the dimmer moons were easy, also eye-floaters which I do suffer with were almost negligible. </p>

<p>Ring A showed subtle dark minima at both ansae, something I have never observed before.</p>

<p>Cassini was very broad and dark black.</p>

<p>Ring B was bright white at the outer edge and steely grey across the rest of its surface, looking slightly grooved in better moments. On the Left hand side I saw subtle irregular dark shading, which I suppose are the elusive spokes, but I did not see them clearly enough to render them as such, again this is a feature I have not observed before.</p>

<p>Ring C was dusky, and easy to see at the ansae, becoming darker and harder to confirm nearer the disc, it was evident across the disc.</p>

<p>The southern hemisphere was a smooth cool grey with no belts seen.</p>

<p>The EZ was bright creamy yellow.</p>

<p>The NEB was a warm brown colour, with a stronger tone along its centre line, and paler edges, the Northern edge was slightly irregular where it bordered the storm.</p>

<p>The tropical region was neutral grey, the colour of cement powder, with a slightly mottled texture and a darker horizontal line towards the left hand half of the disc which divided the storm-belt in two. There was a bright white region to the right hand side, which must be spots, but I was unable to see distinct sharp structure in it.</p>

<p>The polar region was a warm grey.</p>

<p>If I were reading this post I probably would have given up by now and skipped straight to the drawing so it must be time to finish.</p>

<p>As you can tell I had a great session!</p>]]>
