M35 and NGC 2158 – Open Clusters In Gemini

Posted February 25, 2015 by rogerivester
Categories: Observers Challenge Reports

M35 and NGC 2158 have always been favorites of mine.  Years ago when using a 4.5-inch reflector, it could be difficult, especially from my light polluted backyard at that time.  I often used NGC 2158 to determine transparency. 

M35:  102 mm refractor is extremely bright with the most noticeable feature being a curving star chain crossing through the center of the cluster.  The cluster contains mostly bright bluish-white stars.  NGC 2158 appears as a faint, mostly round patch of light without resolution, however, one brighter star (requiring averted vision) can be seen on the western edge.  

NGC 2158:  10-inch reflector at 256x will resolve about 40 or so faint stars.  Excellent seeing and high magnification is required to resolve this beautiful, faint and small open cluster.

The following is a pencil sketch using a No. 2 pencil, blank 5 x 8 note card with a 10-inch reflector at 44x.  Color inverted via computer and standard color sketch…

Carbon Star Observing – The Astronomical League Brings It Back With 100 Of The Finest Carbon Stars In The Northern Hemisphere

Red Star observing was a very popular facet of amateur astronomy from the 1800’s until about the mid-60’s.  Unfortunately, observing Carbon Stars, better known as Red Stars are seldom observed by amateurs of today.

I became interested in Carbon Stars during the mid-70’s, but it would be twenty years until I gained a real passion, or became a serious student of these beautiful and fabulous gems of the night sky. 

In the very early 90’s, Tom English and I became very good friends.  At that time, Tom was a professor of Astronomy and Physics at a local university, very close to my home.

 Tom gave presentations concerning Carbon Stars at some of our astronomy club meetings.  He discussed not only the visual beauty, but also the (B-V) color index scale, explaining in precise detail…exactly what it meant.  I soaked it all in.

I have taken a 12 year hiatus with my observing of both Carbon Stars and Doubles.  A couple years ago the Astronomical League introduced a new observing program, complete with a good quality slick covered book, covering 100 of the finest Carbon Stars in the northern hemisphere.

Due to other amateur astronomy responsibilities, it was impossible for me to start on the Carbon Stars, but things have changed and I’m now ready to start on the list.

I plan on logging my observations and posting on this site.  

The great thing about Carbon Stars…they can be observed in highly light polluted locations and with a bright moon, which is the same for most double and multiples.  

Other than completing the AL Double Star List back in 1996, I’ve also observed and logged well over 200 other selected doubles over the years.  

Just recently, I put my 10-inch reflector into a closet….so it’s effectively in storage.  

I’m planning on observing far less faint galaxies, and nebulae this year, so my telescope of choice will be my 102 mm refractor.  A small to medium aperture telescope is best suited for doubles and red stars. 

My small refractor is also quite a bit easier to set up than my 10-inch reflector.

Celebrating the Universe! Promo

The very first work of its kind, Celebrating the Universe: The Spirituality & Science of Stargazing by James Mullaney is a guide to the wonders of the heavens visible to the unaided eye, binoculars and small telescopes with a focus on the “soul” of the night sky! This travel guide to the stars is written from a metaphysical and spiritual perspective in addition to a scientific one. The unique unifying theme throughout is the personal benefits of communing with celestial wonders firsthand—the joy and heady excitement of participating in the great cosmic drama unfolding nightly overhead. This involves such little-known aspects of stargazing as therapeutic relaxation, celestial meditation, expansion of consciousness, and spiritual upliftment. Based on his more than 60 years’ experience as an astronomy writer, speaker and stargazer, it’s available from HayHouse.com or Amazon.com.

My First and Second Telescopes From The 1970’s

The telescope to the right is my first serious telescope which I purchased in March of 1977, an Edmund Scientific 4.25-inch f/10 reflector.  Feeling the new for more aperture, I purchased the 6-inch Criterion RV-6 a year or so later.  My oldest son Roger Chadwick “Chad” is standing beside both telescopes, and will turn 43 years old this year.   Roger

NGC 627 and IC 1727 – Faint Galaxies in Triangulum

Please don’t be deceived by the cataloged magnitudes for these galaxies. They are much more difficult than you might think due to the very low-surface-brightness.

NGC 672 @ magnitude 10.8 

IC 1727 @ magnitude 11.5 

The following pencil sketch was made using a 10-inch reflector @ 104x, from my backyard with a 5.0 NELM.   Roger
