Sketching Forum's Finalist - Roel:
For the last 2 nights I have made some deep sky sketches with my home build 60 mm F/6,9 achromatic refractor. It's made out of a 20-year-old Novalux 60/415 lens and some spare parts from various other scopes. The chromatic abberation is horrific om Moon and planets, but this tiny telescopes does give me surprisingly pleasant views of some of the brighter deep sky objects. It made me so enthousiastic I want to sketch evering I see through it! I also have a 12,5" Dobsonian but sometimes, when time is short and weather is unpredictable, bigger is not always better!
All sketches are made under a suburban sky. M8 was only 15 degrees above the southern horizon when I made the drawing.
Good Luck to all our finalists!

The Crescent Nebula could be renamed, the Royal Jelly Fish, thanks to your intense photo imaging work. This should be shown in APOD if it hasn't already.
All other entries were also quite worthy.
