Date(s): 10/8/11 (for left field), 11/23/11 (for right field)
Media: Graphite pencils (varying hardness), black gel pen, blending stumps
Additional Information:
I used my 10″ Orion Intelliscope for these depictions, which were both sketches that were originally done separately, but then later combined into one stitched field.The seeing conditions for both depictions were extremely good, as well as transparency. In the future I may also add additional fields to further-expand the view and area. The nebulae also appeared to have a bluish-greenish tint, which was added in post-processing of the scanned image. The most exciting aspect of these observations were probably the fact that I was peering right into a stellar nursery, a place that stars are beginning their lives. I kept thinking to myself, “if only I had a larger telescope…”

This is my first sketch of the sun in H-alpha using my new solar scope Lunt LS60THa. The Lunt Zoom eyepiece, 7.2 – 21.5 mm, was used. Seeing was 3/5.

An exciting day under the Sun. Observing with both a Coronado PST h-alpha & white light 8” Dob fitted with a 3.5” solar filter. Sketches were made at the eyepiece(s).
Seeing was good to excellent. After sketching details of the 4 sunspot groups I could readily see with the PST, I noticed one of the plages (bright spots) on the 1513 sunspot brightening intensely. As it brightened the bottom portion (to the South) of the plage developed a greenish/blue hued widening irregularity. There was also a linear band that extended from the widening directly to the center of sunspot 1513. Above the sunspot there appeared a filament which I tried to capture as well in my sketch. Within 5 minutes the dark patch was gone. From some research and asking more experienced friends, I believe I witnessed a solar flare, probably a minor one but still very exciting. I have been observing with the PST for over a month now, but this was a first for me. The plages around all the major sunspots continued to brighten & fade during the observation period, but none to the intensity of 1513. The PST was loaned to me by a friend after my excitement over white light observing. It’s a wonderful instrument showing many features of the Sun not evident in white light solar filters.
Solar prominences on the limb were also detailed today with the larger one appearing as somewhat of a vortex shape, while another more north prominence appeared as a broken loop. I had observed yesterday & did not see this broken loop then.
I moved to white light observing & could see much greater detail in all the sunspots, including many that did not show up well with the PST.
White light filters are primarily for observing details of the photosphere (like sunspots, facule & granulation), where h-alpha narrow bandwidth shows detail in the chromosphere. The chromosphere or “sphere of color” is the second of the three main layers in the Suns atmosphere and is roughly 2,000 kilometers deep. It sits just above the photosphere, and below the corona.
I am in love with the ever changing face of the sun. I am sometimes tired at night by the time the sky clears but the morning is always mine!

During the beginning month of this year, I could concentrate hardly myself for observing the moon.
One clear winter night, I observed / sketched this landscape on the Lunar limb.
This Northern lunar place is located just above the crater [John Herschell]……..
[P.S]; For a previous lunar horizon sketch….. I had a grave mistake, the place just above [J. Herschell] was not [ Anaximander ], but “‘Here…..[unknown place] is right.
