Mark, you are a superb artist and a great ambassador for astronomy and sketching.
Thank you Erika
I missed your compliment post earlier until rambling through older posts today.
I hope to do more lectures as I provided for a local college and high school recently and showing of the original art.
I am open to any advice for conections to travel and lecture.
Thanks again [and thanks to Jeff for this excellent discussion on the element of time spent in sketching.]
