Learning to See

I've been sketching what I see through the eyepiece practically since the day I got my first telescope, back in 2010. I still have the very first astrosketches I ever made. Here is my first planetary sketch, of Mars, from the night of 14 April of that year.


Pretty crude, I'd say. But I wasn't that experienced yet as to planetary observing, and I was only using a 120mm refractor. So perhaps I ought not be that critical. There's Syrtis Major, plain to see, and a (doubtlessly oversized) polar icecap. (To see the sketches/paintings at full resolution, just click on the image)

2 months earlier, I had finished this drawing of my first sighting of the Asteroid Vesta.



I'm fairly sure that this is my first ever astrosketch, since I have nothing older than it (and I don't throw anything out). I began it on 14 April, but didn't finish it until 2 nights later. On the 14th, I wasn't sure which of the 2 "dots" at the lower left was the asteroid. It wasn't until my second look on the 16th that I could see which one had moved.

Well, time rolls on, and my observing skills gradually improved, as did my practice at recording what I saw. For evidence of such, just look at this 2014 sketch I made of pretty much the same face of Mars that I had drawn 4 years earlier.



The scope used here was actually smaller than I one I was looking through 4 years earlier (only 90mm), but my eye was far better trained... and it showed!

The high point (so far) in my sketching career was when, on a whim, I sent in one of my lunar sketches to Sky and Telescope magazine, and by golly if they didn't publish it! (June 2016 issue, page 73) Here it is:


Hundreds of sketches later, I am still a passionate advocate of the practice. Sketching an object compels you to PAY ATTENTION to what you're looking at, to notice little nuances. Is that crater wall brighter than the one right next to it? Is it more jagged, more broken up? Which mare is darker - the Sea of Tranquility or the Sea of Serenity? And why do you think they're different?

When sketching Saturn, I find myself noticing detail that I might miss when just looking at it, such as the planet's shadow on the rings, or subtle variations in color on the surface (much harder to detect than with Jupiter).

Now most HAL members know I have a fondness for tracking down anonymous uber-faint stars. Sketching the field of view after successfully spotting them makes going back to them all the easier, because you've fixed the environment in your mind. Many years ago, I used to teach Russian at Howard Community College. I discovered that the more parts of the body a student used in learning the language, the faster (and more permanently) he expanded his vocabulary. Just reading a new word was practically useless, as far as memorization was concerned. Saying it aloud was much better. But best of all was writing it down. (Actually, better than "best" was to do all 3 at once.)

The same goes for stargazing. It's a full body sport. Just looking at NGC whatever is good, as far as that goes. There's no way to "say it aloud", so let's just skip over that step. But sketching the danged thing? Aaaah, now that's the ticket! I guarantee that you'll remember the difference between M13 and M92 after you've sketched them both, and you'll appreciate their differences.

Now lately I've expanded my repertoire a bit, and have taken up watercolor painting. (A lot harder than I anticipated before getting into it!) What with the execrable weather of late, plus another round of health scares, I haven't had much opportunity of late to "paint the sky", but I have been practicing on some more mundane objects - like trees. Here are a few examples of recent work:




Trees behind the Pool Club


Medieval Tower in Bavaria


Storm Clouds over the Austrian Alps


"This Painting Belongs on a Motel Room Wall"

Now once again, painting trees has forced me to really look at them for the first time. I never before noticed just how radically sunlight alters the perceived color of leaves, how much variation there is in light and shadow, how many varieties of shape can be seen in even 2 examples of the same species.

I hope to be able to turn my attention skyward in the next few weeks, and make use of this new (to me) medium. I'd like to get similar benefits from painting the Messier catalog. Stay tuned!
