The enigmatic Cartwheel Galaxy is a tough enough object to observe let alone sketch.
During a nice clear night in December I made an attempt to sketch it as accurately as possible to the actual eyepiece view, and I was reasonably pleased with the end result.

The trouble with the Cartwheel is that it is quite faint and ill defined in most amateur telescopes, as averted vision is required to capture glimpses of the more subtle features of the object.

To sum up the galaxy is visible as a soft oval glow some 2.0′ x 2.0′ in size, with the two unusual companion galaxies around 1.3′ to the left as can be seen in the sketch.
Another galaxy some 2.0′ above and slightly to the left of the companions was also visible, this galaxy has no relationship with the Cartwheel.

Sculptor was getting a bit low in the west whilst I was doing this sketch, but it was possible during moments of steady seeing and using averted vision to just barely make out the ring structure, but it was very faint.

I could not detect any hint of the “spokes” as seen in the Hubble image, but with a larger scope and steadier seeing they could quite possibly be a chance.

The brighter more active star forming region of the galaxy was discernible as a slightly mottled curved patch some 1.6′ x 0.4′ in size, as can be seen slightly off center to the lower right.

I have included a duplicate reference sketch for those unfamiliar with this elusive and very rare object.

Part of Basin Schiller – Zucchius
Sketch and Details by Frank McCabe

After 12 cloudy days and nights I was anxious to get out under a clear sky to make an attempt at sketching a lunar target of opportunity. Before selecting a target I noticed the moon was moving through the Pleiades and created a very interesting binocular target. With the moon at 12.5 days into the lunation, the waxing gibbous phase was showing me the Schiller – Zucchius basin very nicely. I centered on two craters to one side of this 3 ringed basin. First the young Copernican period crater Zucchius (65 km.) with its terraced inner walls and shadowed floor looked deeper than its 3.3 km. measured depth because of the light and shadow. Sharing a common wall with this crater is the ancient and similar sized Segner (68 km.). This pre-Nectarian crater looked old and worn. Its rim was low and had nothing in the way of central peaks just a small nearly centered crater Segner H. Extending from the north side of crater Segner’s outer rim is a ridge which is a short wall segment of the second basin ring. What looks much like a shallow depression and measures about the same size as these two craters is the central ring of the basin and can be seen at the lower left (Northeast) in the sketch.
A photo of this entire basin credited to Gary Seronik can be seen on LPOD for October 17, 2004

I found myself sketching quickly in the cold air which was rapidly dropping in temperature as I sketched. After about an hour I considered the sketch finished and returned to the indoor warmth to thaw out.

Observing site: Hoshinomura
Transparency/seeing/sky darkness: 2/4/2
Instruments: 30×125 binoculars
Width of field: 1.6‹
This is the brightest and most interesting diffuse nebula among those that are visible from Japan. It shows very complex structures and extremely difficult to draw. North of this nebula a diffuse nebula called NGC 1977 is clearly visible.
NGC 1999: This nebula is relatively bright with complex structures. If this nebula was a separate object, it could attract more attention of observers.
M42: Even at this magnification the four stars of the Trapezium are resolved and a dark band intruding the bright nebulosity from the east is noticeable. There are three stars along this dark band. There is also a dark band south of the Trapezium.
M43: The star at the center stands out and the southeast side of the nebulosity is sharply defined by dark areas.

Sketches and Details by Dale Holt

I have assembled three sketches made at my hand over the Christmas holiday. The first caught my eye because of its shape under the illumination on the evening of observation. It struck me how it looks like a ‘love heart’ I later researched and found that this worn and likely flooded feature? Was Wolf no longer a Wolf’s den! But in my sketch perhaps a Wolf’s heart?

The second of my sketches, and personal favourite of the three is of the magnificent mountain range, Montes Harbinger, I was drawn by the brightly illuminated peaks and anthracite black, jagged and far reaching shadows reminiscent of the angry wood hungry teeth of an old rip saw!

Finally for the of my trio, completed last night it depicts the giant foot print of Schiller, seeing was good and detail plentiful, a wonderful way to spend an hour.

I hope these trio find favour with you? Drawn using my 6″ refractor in all cases & rendered with pastel & watercolour pencils upon black artist paper.

Happy New Year, Dale

It had been a while since I visited the Bug Nebula.
As Sagittarius was getting a bit low in the west I thought I might catch it before it went behind the trees.
I was pleased with the eyepiece view and remembered the Hubble image of it.

While the Hubble image wins hands down with subtle detail, the view through a large aperture dob is certainly nothing to be ashamed of.

I have made numerous attempts at sketching this remarkable globular cluster over the years, mostly in small telescopes at low power where it is just a bright ball. At higher magnification in my 56cm dob it is a vastly different object.

I had a dose of the Flu while I was away observing, but the sky was clear so I spent a solid two hours at the eyepiece sketching this globular, and it nearly done my head in. Every time I looked in the 8mm Ethos there seemed to be more and more stars to add, plus the 100deg FOV of this eyepiece was almost to much to handle.

The following night was clear again so I spent another 40mins just dabbling with the sketch to try and get as accurate eyepiece view as possible.

I have never been 100% satisfied with the sketches I have done previously of NGC 104 and most made the bin. This one however came out fairly good, it is certainly the best I could do with 47 Tuc.

I do not like to overdo eyepiece sketches, especially with size and brightness as one can be tempted to get a bit carried away, and detract from the visual perspective.

There has been no processing done with the sketch.

I do not think I will be doing NGC 104 again any time soon.
Too many stars!

Crater Euclides and Montes Riphaeus

Crater Euclides and Montes Riphaeus

Crater Euclides and Montes Riphaeus
Sketch and details by Frank McCabe

In southern Oceanus Procellarum not far from mare Cognitum you can locate a bright little Copernican era crater that formed after the last of the dark lava had solidified. This little 12 kilometer crater wearing the bright ejecta blanket is Euclides. The bright ejecta makes it easy to pick out at high sun and with a little bit of shadow and high magnification the nearby Riphaeus mountains also show some fine relief. In the upper left of the sketch note the front range of these mountains which date back 4 billion years. These mountains are likely the remains of a very large crater rim that was not completely buried in the lava flooding. Other similar sized and smaller craters in the region also reveal some bright ejecta betraying their young ages. To learn more read the LPOD caption for May 24, 2006.

The Will to Sketch: Trifid and Eagle

Emission/Reflection nebulae M-20
Sketch and Details by Serge Viellard, translation by Frank McCabe

Superb stay organized by the astronomy club in La Palma from the 9th to the 18th of October, 2009. We spent 3 nights at the top of the volcano (2400 m), next to the professional domes in a universe under a very good sky, well above the seas of clouds. This stay will remain marked by the will to carry out the portrait of the nebulas known as the Trifid and the Eagle. Both were marvelous to observe so well in the 16 inch scope, the vision abounds in details, differently highlighted according to filters used which allows these colorized drawings L, R (H-beta), V (OIII). I was encouraged to remake the drawings of the first night on pre-drawn star fields made during the next two nights, that in order to gain more precision. I appreciate in the Trifid the incredible complexity of the various dark channels, noting their particular forms, the meanders and their notches. I would have spend more time on the lower parts of nebula but the object was visible only a little of time at the beginning of night. Then comes the time to observe the Eagle with its notable and significant “pillars of creation” and incredible detail. Their perception varies according to the magnification employed and filters used. They are well highlighted with the UHC-S filter and a magnification of 220x.

Mars Glides Past the “Beehive”

Mars Glides Past the “Beehive”

Mars and “The Beehive Cluster”
Sketch and Details by Michael Rosolina

The clouds parted over West Virginia the other night allowing me to view Mars shortly after it passed in front of Messier 44, the Beehive.

I made this widefield sketch in order to capture the star cluster and its two attendants, Asellus Borealis–the Northern Ass and Asellus Australis, the Southern Ass. In Galileo’s time (about 180 years before Charles Messier catalogued it), M44 was known as Praesepe, the manger, where the Aselli ate their hay.

Praesepe was one of the objects that Galileo scrutinized with his new telescopes, discovering that it was a star cluster and not a nebula or cloud as previously thought. One of his scopes had about 15x, although he didn’t enjoy nearly the field of view that I had with my modern binoculars.

I made this sketch in the field with color pencils on black paper. I couldn’t give Mars the luminous appearance that I observed using color pencils on black paper, so I tweaked it a little digitally.

I am dedicating this drawing to a friend who passed away not long ago. Eric realized his dreams of astronomy by becoming an operator of the 100 meter radio telescope at Green Bank, West Virginia.

Best regards,

Michael Rosolina

Comet Hale-Bopp
Sketch and Details by Per-Jonny Bremseth

Hey!
I send you comet Hale-Bopp, “a great visitor!”

I dont know if you like older sketches, but to me the comet
was so splended and great, that I never can forget it!
Well, I made this observation with 10 x 50 binocular when the
comet was near brightest.
I used crayons (watercolour) on black paper only.
Location: outside Trondheim city, Norway.
More info on my sketch.
