globular clusters (selected images)
 

Messier & NGC Observations

My love for globular clusters started from the moment I viewed my very first one. It was through a 6 inch Criterion telescope, the object was M13, the "Great Hercules Cluster" located in the constellation of Hercules. As compared to other objects that I had seen, this was the first time that I saw something in a telescope that acutally looked like it did in one of my libray books. From that point on I was hooked! Starting with the Messier's, to NGC's, Palomars and then the Terzans. I have now both observed and imaged all the visual gloublar clusters of the Milky Way galaxy.

Palomar & Terzan Observations

The Palomars are some of toughest globular clusters to catch a glimpse of. Though I have been able to view many with direct vision, others required a good deal of time using adverted vision. Other problems included coordinates that are somewhat questionable. Also, the potential to see something that may or may not be there...especially after hours at an eyepiece. Eye fatigue can play tricks with your vision. So to confirm these observations and their respective coordinates the need to image these objects are an inportant part of the observational confirmation process. The Terzans present themselves as the most diifcult to both observe visualy and to image. These objects are not only faint, sitting behind good amount of dust plus thier infrared qualities, they also sit low in the sky for those (like myself) from the northern hemisphere. Their visual magnitudes run from 12 to 17.5 with the average magnitude coming in at around the 13 to 14th magnitude.

Imaging Observation Notes:

The imaging results vary from fair to good to very good.  Though the original idea was to get the best quality image…well sometimes it comes down to just getting an image. My intentions will be to re shoot images to obtain the best quality when the time becomes available...some already have been "re-imaged." Shooting Palomars and Terzans produced many images…some not of the best quality…but workable images none the less.
