The Deep Sky from Birmingham
Although I have never professed to being a deep sky observer, I have occasionally taken time out to sketch many Nebulae & Galaxies. I include a very small sample here merely to show that observations of these faint and often very diffuse objects can be made VISUALLY from heavily light polluted skies - without filters!
