If you want to be more "poetic" read the observing lists by the greats. People like Reverend Webb, Admiral Smyth and others. Reading their entries is almost like you can see it in your mind, like a well written novel.
I'm here to do two things, build something and dump some light down it.

Hello kt4hx,

Thanks for a wonderful article on DSO observations. DSO's are my favorites' for observing, especially the Golubar Clusters like M13.
You pointed out in your article about the different features to be on the lookout for in DSO's. I found this interesting because i was
unaware these facts. So I have something to strive for in my future observing sessions. Thanks for the work you have done in putting
together your article, it was what I was looking for. I recommend this article, it is well written and highly informative.

Thank you Kip. I am glad that you found it useful for your observational planning, and I hope it is proves of practical use in the field.

Seeing various details in DSOs is a skill that we should work toward. The more time we put in at the eyepiece, the more this skill solidfies. When we have been observing a few months it can be interesting to re-visit some objects that we first observed as beginners to see how our skills have improved. Over the course of time, with more and more observations under our belts, we gain perspective of what we are looking for, thus making the process of finding objects easier. Our eyes become accustomed to looking for varying levels of light within objects and that is when details begin to emerge and make sense.

I am also quite fond of globular clusters as they are my second favorite type of DSO after galaxies. Typically the first impression of globulars is that they all look alike, so when you've seen a few you've seen them all basically. That is most certainly not the case. While there are definitely some similarities between many of them, and aside from some being obviously much brighter than others, there are many subtle differences between them as well. The more globs that we observe the easier it becomes to notice the differences among them. Just because we don't always see the differences initially doesn't mean they aren't there. Being the kind of skilled observer we wish to become takes dedicated practice to train the eye, and the mind as well. So good luck with your observing and your progression along the learning curve. :)
Alan
