Caldwell 21 (NGC 4449) is an irregular dwarf galaxy in Canes Venatici. The sketch was made from my suburban backyard just outside Ottawa, Canada on June 19, 2014 in graphite on white paper. The sketch was then scanned, cleaned up and inverted in Paintshop Pro. The view is through my 120mm f/8.3 achro refractor at 77 X. I completed the sketch using my non-dominant eye 6 days after cataract surgery. With the new lens this eye is now much sharper and brighter than my dominant eye.
