Hi Shannon and Welcome to CN and the Sketching Forum!

There's another angle to the use of Dobs as it relates to sketching. I used to sketch with a 20" Starsplitter II (still do on occasions). It was the only scope I used for my first couple of years of sketching. What it trained me to do was to quickly memorize a feature size, position and context. I would add it to the sketch and repeat, as you put it so well, "sketch and scoot, sketch and scoot". After a couple of years doing this, I could very rapidly assess the details and I discovered I could sketch larger areas or include more detail in smaller views.

So cherish the time you spend sketching at your Dob, it could be one of the best ways to extend your skills.
