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

NGC 404 – Galaxy In Andromeda – Known as Comet Komorowski and Mirach’s Ghost

NGC 404 has been confused as a comet on many occasions by amateurs over the years.  However, most of this confusion occurred during the 60’s and 70’s.  This galaxy was not plotted on most popular star atlases during this era.  One such occurrence, was made by a young Charlotte amateur in 1964, whose name was Ted Komorowski.  To read the entire story, please click on the latest Las Vegas Astronomical Society, Observer’s Challenge link as following:

California Nebula – Six Hour Exposure Using a 71mm Apochromatic Refractor

Categories: Uncategorized

Today I received this beautiful six hour image, made by Dr. James Dire of Hawaii, using a 71 mm apochromatic refractor.  Jim said he saw it visually last month, using a 10-inch Parks f/4, but was barely detectable, due to the large size of the nebula, which is 2.5 degrees in length.  

Dr. Dire is interested in selling the 10-inch Parks reflector OTA:  This telescope has a new $350 Moonlight two speed focuser, also included is a Tetrad.  A great quality scope.  Price:  $700 shipped.

“Finally….after more than 35 years, I was able to see Sirius B, better known as the “Pup.”

Date of observation:  March 14th 2012

Telescope:  4-inch Orion/Vixen f/9.8 achromatic refractor

Conditions:  Excellent seeing and transparency 

Location:  My moderately light polluted backyard in the foothills of western North Carolina   

How did I become interested in this famous star and its faint companion?  I purchased my first serious telescope in 1977, which was a 4 1/4-inch f/10, Edmund Scientific reflector.  Even though this was not my first choice for a telescope, it was the best my budget would allow at the time.  I really wanted the 6-inch Edmund f/8 EQ reflector.  

I started reading everything about astronomy I could find, and really liked “The Edmund Sky Guide”  by Terence Dickinson and Sam Brown.  There was a paragraph or two, concerning Sirius and its…

Observers Challenge Report:  OCTOBER 2014 OBSERVERS CHALLENGE – NGC-7640-2

Visual description:  10-inch reflector at 183x from my moderately polluted backyard, this galaxy is faint with an overall low surface brightness.  It is elongated NNW-SSE, with a subtle brightening in the central region, and is situated inside a triangle of three fairly faint stars.  roger

SEPTEMBER 2014 OBSERVERS CHALLENGE – M-030-1

Bright and well concentrated globular cluster. Using a 10-inch reflector, at 195x some partial resolution of stars. The cluster is elongated E-W, with two distinct star chains radiating out toward the N and NW. A fainter chain extends NNE. The most northerly chain is comprised of four stars. When using a 102 mm refractor, the star chains could not be seen, but the edges appear very irregular, with a brighter middle, and with an E-W elongation.

M30 has always been one of my favorite globular clusters, due in part to the unique star chains extending out from the very bright central region.    Roger Ivester
