I own a 150mm dobsonian reflector telescope at home (Looks like a canon) and I wanted to know if anyone here has ever heard about astronomical sketching. When astrophotography is not a viable option for an amateur astronomer who wants to capture what he sees through his telescope in an image, he may decide to make a sketch of what he sees through his telescope on a pad of paper. Due to the risk of potentially blinding out night vision, red light is used to illuminate the paper when sketching an image seen through a telescope. The image may either be drawn as a negative on white paper with a pencil and later inverted in an image editing program or the image may be drawn on black paper with a white pencil on site.
I have been wondering if it is feasible to use Krita on a tablet computer to sketch images seen through a telescope on screen. My major concern would be risking losing one’s night vision when staring at a bright computer monitor. This risk could be reduced by using a custom “night vision” theme that displays all color as red and by creating the image in grayscale when working outside. I myself have not done much astronomical sketching other than sketches of bright planets and the moon, but I have read several articles on this topic in Astronomy monthly magazine covering this topic. Mostly, the authors for these articles use physical drawing media other than for inverting the color of negative drawings, but it might be possible to use Krita for astronomical sketching with some tweaking.
I can’t find any sketches I have made in the past so I will share a link to a YouTube video explaining the process:
