Siegfried1969 Posted June 11, 2023 Share Posted June 11, 2023 Two observations from Friday morning with my TAL-1 11 cm Newton telescope. First test of my new Astronomik UHC filter and the effect of this filter is really impressive. Especially on M57. However, the conditions were not good with a lot of light pollution, both direct and indirect. For the sketches I used: Canson black grained paper 160g/m2 A white pencil Sakura white gelly roll pen A malleable gum Siegfried 10 1 Link to comment Share on other sites More sharing options...
