NGC 1579 – “The Northern Trifid” – Reflection Nebula in Perseus – February 19th 2013

December 19, 2015

NGC 1579 – “The Northern Trifid”  Reflection Nebula in Perseus 

Date: January 31st 2013 – Telescope: 10-inch f/4.5 reflector @ 104x – Location: Moderately light polluted Backyard in western North Carolina with a NELM 4.8 

Faint and very diffuse with a brighter oval shaped middle.  The texture is somewhat mottled and uneven, and at least two dark lanes can be seen with averted vision (see sketch).  The nebula has very uneven edges which fade very gradually outwards.  A 12M star lies just to the NE, and a group of four stars to the south make the shape of a dipper.  This is a most interesting object which seems to be overlooked by many amateurs.  The following sketch was made using a 5 x 8 blank notecard, a No. 2 pencil, and an eraser.  The color was inverted using a scanner…

Thank you for visiting my site and I’m hopeful you’ll find it interesting.  

      DSCF5178 

6-inch f/6 Newtonian which is now becoming my favorite telescope, due to the smaller size and weight.  

The following Celestron 4.5-inch Newtonian was a gift to me by a friend. Libby called me one afternoon and asked if I could find a new home for this telescope. So, I went to pick it up and did a serious evaluation, and decided that it would make a good edition to my current telescope inventory. The telescope was in pristine condition…how could I turn it down? And It’s compact, fairly light and very easy to set up on a Vixen GP mount. If I want to attempt to some very faint threshold deep-sky objects, I can use the following CGE-Pro Celestrom GoTo mount.

102 mm Vixen/Orion refractor. I purchased this telescope in 1997 and was a bit surprised how large and heavy this f/10 telescope was.

The following 80mm f/5 refractor was a gift to me by my son Brad, living in Las Vegas. My most portable telescope.

My other hobby: Still riding a bicycle as of current with about 135,000 miles since June 1979. However, it took me 29 years to log 100,000 miles in October 2009. I continue to ride even to this day, but not as fast or as many miles.

As following: A good illustration how faint the Helix Nebula appears via a 10-inch Newtonian with a nebulae filter. This planetary appears nothing like a beautiful time lapse, colorful, filter enhanced digital image. A chalk and black card stock sketch was best used to present the true appearance of an eyepiece view of the Helix.

I’ve never used a computer or any other electronic means to enhance or embellish my visual eyepiece sketches.

Orion nebula: I’ve always felt there is just too much fine detail to properly sketch this famous nebula. The following sketch was made pretty fast, attempted to only draw the most prominent features. Each and every time I’d turn my telescope(s) toward the nebulae to attempt my best ever sketch….I’d become overwhelmed, and would move on to other deep-sky objects.

Hale-Bopp with the anti-tail, gas and dust tails easily seen with a 10-inch Newtonian: Chalk on black card stock, worked best for the famous comet.

NGC 7789, Open Cluster in Cassiopeia

December 14, 2015

NOVEMBER 2015 OBSERVERS CHALLENGE – NGC-7789 

NGC 7789, Open Cluster in Cassiopeia:  Location of observation:  From my moderately light polluted backyard in Western North Carolina 

Observer:  Roger Ivester 
Date: October 7th 2015
Conditions: Good   NELM: 5.2
Telescope: 10-inch f/4.5 Newtonian Reflector
Sketch Magnification: 104x    FOV: 0.79º
Catalogued Magnitude: 6.7

Very bright and rich with well over 120 stars counted with the 10-inch. The cluster stars encompass an area of about 25 arcminutes. Loops of stars with dark lanes throughout, but mostly a random scattering of stars. A fairly bright, mag. 9 star is located just off the cluster edge toward the west.  

Pencil Sketch with inverted colors.

The following notes and pencil sketch (with inverted colors) of NGC 7789:  By Jaakko Saloranta of Finland

Despite poor observing conditions a rich and very beautiful cluster.

Strong background glow is lost at high magnification.  Several dark pathways visible within the cluster as starless regions.  

Brighter stars concentrated towards the W edge. ~80* within 9′ down to 13th magnitude.  Resembles an open rose.
