So I turned to some bright Messiers. The first sketch (M38) looked very good, so I tried a second (M36). Meanwhile the temperature was dropping (my SQM said it was -8°C). And when I finished M36... why not sketching the third OC in Auriga?
That was too ambitious: I was tired, half frozen and M37 was the most difficult of the three to sketch (a lot of faint stars). Halfway the sketch (I did the N-side), I stopped to put all the stars in detail on paper. The S-side is rather an "impression".
The most difficult about sketching an OC for me is the brightness of the stars. I tend to draw stars bright or faint. But nothing between the two.
All comments are welcome.
