JULY 2018 OBSERVERS CHALLENGE – M-004

Notes from my backyard:

Globular cluster, M4 is easy to see with a 60 mm refractor, appearing as a faint circular glow at low magnification.  When using a 3.5-inch Maksutov-Cassegrain at 78x, there is a resolve of some of the brighter members.  The cluster has a subtle elongated shape.  A very faint chain of stars was noted in the central region, oriented N-S.  With 102 mm refractor, there is a greater number of stars resolved within the cluster, and much greater concentration of stars, elongated and with more stars in the central chain. A prominent double star is located on the SE edge.   

10-inch reflector at 140x, excellent resolve of the cluster. The center chain of stars is very bright and with many stars counted, both in the central region and around the outer edges.  A chain of stars makes an arc, the entire length of the cluster on the NW side.  The elongation shape becomes much more apparent with the larger aperture.      Roger Ivester

What? Sand Dunes In The Northeastern Corner Of South Carolina, 50 Miles From The Atlantic Ocean! And Also Very Dark Skies

August 14, 2018

While visiting family in Mullins, South Carolina over the past few years, I’ve discovered some fabulous dark-sky areas, perfect for the use of an astronomical telescope.  

Only a few miles outside the city limits, there are country roads, agriculture fields, and no houses or lights for miles and miles.  

Hopefully in future visits, I’ll be able to take one of my smaller telescopes, but unfortunately, like most all locations on the east coast, cloudy skies seem to prevail.  

However, this trip yielded some beautiful skies, but on our first night we were too tired to attempt to see the Perseid meteor shower. 

The next morning….Tuesday August 14th 2018.  

When driving in a secluded area, via unfamiliar country roads, you never know what you may find:   

While riding around with my oldest grandson, who just got his learners permit, and I was sharing my wisdom, of how to be a safe driver.  During our  leisure drive, we found something very interesting:  

Sand dunes, and a very sandy area….at first resembling snow, all in the middle of a dense forest and surrounded by swamp land.  There were Bald Cypress trees growing out of the black murky water, Spanish moss hanging from the trees, and who knows…..maybe even an alligator or two in that dark water!

Note:  This very remote small sandy area is a protected site.  I took some pictures as following, but somehow missed the eerie swamp.
