After 4 years of “try & error” with a faint NGC 7293 in the horizon haze of central Europe I finally finished “my Helix”, using the 24” Dobson at Hakos Guestfarm in Namibia. No haze, but 70 degrees high in the sky, the Helix was an impressive beacon, details were easy to report. I wasn’t prepared to see the halo, my template was too small to sketch it, so I had to use a second sheet. Seeing was moderate, I didn’t see the faint background galaxy 2MASX, but… nevertheless I enjoyed it!
Object Name: NGC 7293, the Helix Nebula
Object type: Planetary Nebula
Location: Hakos Guestfarm, Namib Naukluft, Namibia
Date: June 4th, 2014 (about 2 hours total of sketching)
Media: Pastel and graphite pencils
Optics: 24” Dobson f 4.0
Field is about 30’ wide, east is up. To concentrate on object (and not on dimensions) I used a pattern of stars printed from Guide 9 as a template. Pinpoint stars added by image processing software (to replace printed and sketched stars)
