A faint nebula in Cassiopeia

 Hello,

This object was brought to my attention by Sue French (Celestial Sampler). While Cassiopeia dominated the zenithal region of the sky, I tried my luck. The nebula was visible at x15 as a small patch around the star Burnham 1. How nice! The nebula showed even more details at x36. It was a pleasing sight in my little scope. The associated star cluster, IC 1590 remained invisible with the used set-up. Here is my impression.

Pluto From Pluto

Pluto from Pluto

“Pluto from Pluto” after Mel Hunter
By Frank McCabe

  In the spring of 1963 I was a junior in high school and purchased for 75 cents a
Pyramid book titled “Nine Planets”. The author of the book, Dr. Alan E. Nourse
worked his way through medical school by writing magazine articles about science
fact and also science fiction. I found this author’s writing style riveting as a
young lad. Today most of the content of this book is quite outdated although in
1963 it was an exciting read. Planet Pluto, the “Mighty Midget” as the author
describes it is more unknown than known and will be explored. The author
speculates on the nature of this mysterious planet in the chapter titled, “Pluto
and the Outer Reaches”.
  So this chapter too will become part of the discarded speculation of the past
because in another 7 years new information about Pluto will be gathered by the New
Horizons spacecraft during the July 2015 close
encounter.(http://pluto.jhuapl.edu/) At that time the former planet Pluto will go
from unknown minor planet to known minor planet.
  The author had some wonderful assistance in writing and proof reading the book
from well known artist Mel Hunter. Eight of his beautiful paintings are shown in
black and white and can be found between pages 128 and 129. The last one “The
surface of Pluto, with the Sun in the distance” was the one I was looking at to
create this color crayon drawing that I made in the spring of 1963 some 45 years
ago.
  I requested and happily received permission from Mel Hunter’s widow sculptor Susan
Smith-Hunter to make this post.

Splendid encounter

Moon and Pleiades 

Hello astronomy’s lovers, this is my last sketches of Moon and Pleiades.The sky was
clear, but strong windy make many difficult for made the drawings. I stay in my
observation site in front of my home with bino 16×80 on the heavy wood’s tripod and
inox column, all very steady fortunely!!I make the first sketch at 8,25p.m.,second at
8,50p.m., last at 10p.m. What fantastic vision!
Title:”Splendid encounter”

A Fine Reflection

NGC 7023

NGC 7023 or Caldwell 4
By Rony De Laet

Here is an observation of an interesting nebula (aka Caldwell 4) in Cepheus. A nebula filter is of no help at all (and I tried ) because it’s a reflection nebula. I once was quite happy with the Baader Contrast Booster on this object, but this night no filter was able to enhance the view. The object was near zenith during the observation. The nebula kind of grows in the eye of the observer. First I see a halo around the central star (HD200775). Then with patience comes a bar of light running from N to S through the star. With a lot more patience and wiggling the scope, the nebula grows larger and reminds me of a face on galaxy with knots of nebulosity and dark lanes cutting the disk. A faint star is visible in the N part of the nebula.

Head of the Twin

Castor

Alpha Geminorum or Castor
By Wade V. Corbei

Geeze…I so enjoy the oncoming winter and the splendid objects and constellations that it offers. Below is a sketch of Castor, the double star that makes up one of the “heads” of Gemini, The Twins. In Arabic Castor is called Al-Ras al-Taum al-Muqadim, meaning “The Head of the Foremost Twin”.

Both stars seemed close to the same size and magnitude, being 2.8 and 2.0 respectively, with just a hint of a blue fringe around both. A close double that is easily split with higher magnifications.

One Neat Comet

Comet C/2001 Q4 NEAT

C/2001 Q4 NEAT on May 14th 2004
By Martin McKenna

C/2001 Q4 NEAT on May 14th 2004 at 23.43LT through the 16″ F/4.5 reflector. The comet was a naked eye magnitude 3.7 object with a coma diameter of 20′ and a tail over 50′ long pointing to the NE through broken cloud. It was located in Cancer below the ‘Beehive Cluster’ (M44) low in the SW evening twilight at 71 degrees elongation from the sun. Overall the comet was a slight green colour with a broad fan shaped dust tail.

The rapidly rotating Earth placed the comet behind a tall tree in my back garden so I had to observe it through the gaps in the branches causing the comet to fade then brighten as it passed natures foreground obstructions in the telescopic field of view. Conor was also with me during this observing session who tracked the comet using my 8″ S.Cass – this was his first bright comet. Later Q4 NEAT dropped from view and joined T7 LINEAR – a situation that provided southern hemisphere observers with two naked eye comets!

Lunar Sketching More Than a Century Ago

Historical Lunar Sketches

Historical Lunar sketches
By Dr. Ladislaus Weinek

More than a century ago at the Prague (Klementinum) Observatory Dr. Ladislaus
Weinek served as director of the observatory beginning in 1883.  Professor Weinek
lived from February 13, 1848 to November 2, 1913. He is best remembered for
combining images from Meudon Observatory in France and Lick Observatory in the
United States into the first photographic atlas of the moon in the 19th century.
On the surface of the moon to the southwest of Piccolomini a 32 kilometer crater
is named in his honor. The professor was also an accomplished lunar sketch artist.
The drawings above were made by him and appear in the work titled: The Amateur
Astronomer by Gideon Riegler with English translation by Geo. Aubourne Clarke,
1910, London, T.Fisher Unwin. These drawings can be seen in  chapter IX on pages
200, 201, 206 and 207. In this lunar chapter there is an interesting paragraph
that describes amateur astronomy at that time. It reads “… The amateur astronomer
who takes up the  observation of lunar details can, as we see, aid the professional
in many respects. The possible fields of observations on the lunar surface is so wide,
and contains so many interesting details, that a whole lifetime is scarcely sufficient to
enable one to make observations on every part of the moon’s surface, and even the
longest experienced investigator of the moon will scarcely find himself in any difficulty
as to which detail he will make the object of his observation.”

Ringed World With “Children” in Tow

Saturn

Saturn, March 3rd 2008
By Carlos E. Hernandez 

I made an observation of Saturn on March 3, 2008 (03:45 U.T.) using my 9-inch F/13.5 Maksutov-Cassegrain (163x). I noted a good amount of detail over the globe and rings. Both the South Equatorial Belt (SEB) and North Equatorial Belt (NEB) were visible as brownish-reddish bands. The South Polar region (SPR) appeared brownish with a dark center. The North Polar Region (NPR) was also brownish. The inner portion of Ring B was dusky (4/10). Rhea (9.8m) and Dione (10.2m) were visible north and following the planet. Titan (8.4m) was visible preceding and south of the planet.

Raised, Tilted and polygonal

Aristarchus Plateau

The Aristarchus Plateau
By Frank McCabe

The Aristarchus Plateau
  
  The 3.6 billion year old Aristarchus plateau is a raised, tilted polygonal block
of crust in the ocean of storms with a collection of interesting features that can
be seen with telescopes of all sizes. Crater Aristarchus left of center is a large
(41 km.) 3.2 km. deep crater that is bright, young (500 million years old) and
sits near the SE edge of the plateau.  Lunar Prospector spacecraft back in 1998-99
detected radon gas being released from this region. The Space Telescope Science
Institute along with Northwestern University and others conducted an ultraviolet
and visible light analysis using the Hubble telescope to detect the presence of
titanium oxide near crater Aristarchus. This could be a potential source of oxygen
on the lunar surface and also a source of titanium metal.
   I remember well my disappointment when Apollo 18, 19 and 20 were cancelled in
1970. Apollo 18 was scheduled to land on the Aristarchus plateau near Schroter
valley. Schroter valley is an old Imbrium (3.5 billion years old) volcanic
feature that begins at the famous cobra head 25 km. north of ancient crater
Herodotus. This feature meanders north then west then southwest for more than 150
km. The bend is nearly 170 degrees. It is also large enough to be seen in a 2
inch telescope under conditions of good seeing.
  The region surrounding the beginning of Schroter valley was carefully imaged March
3rd and April 27th in 1994 by Clementine spacecraft because of reported color
changes. Clementine confirmed these changes were real. This region of the moon
shows color visible to some observers. It is described as reddish or yellowish by
those that can see this color.
  Don’t think of the moon as an annoyance that spoils galaxy hunting as some deep
sky enthusiasts sometimes do, but embrace it as the beautiful satellite it is,
awaiting observation and exploration.
