Hey everyone. So I was doing some searching online for some tips and tricks for moon sketching since it is still new to me. I came across an article called The Art of Drawing the Moon (https://britastro.org/node/9529) where the elger instensity scale is mentioned, and my first time ever hearing about it. I've been wanting to setup a cheat sheet with examples of the scale 0-10 visually so I can use that, instead of constantly referring to a moon atlas for the scale. I was curious if anyone else has setup this scale, or uses this scale. If you have already setup a cheat sheet and happen to have it scanned I would appreciate that. Wondering if everyone else does like I have done with my few moon sketches so far and just do all the shading at the eyepiece? The thing that is motivating me to make this scale is so that I can do the most time consuming part--shading and shadows--inside now that it is quite cold outside. I really like the idea of sketching the outline at the eyepiece while labeling each section with the scale number so you know the shading needed for the drawing once you're back inside in a nice warm house.
