Observing notes:
Although my SQM and SQML gave rather low values, the sky was remarquably transparent. Light pollution is totally absent from the Observatoire des Baronnies Provençales, overall excellent conditions to observe a large and faint target.
vdB 93 is an interesting nebula because of its dark lanes from each part of its lighting star. With patience, they can be analysed and sketched with a lot of details.
Numerous stars are scattered in the halo, which presents a beautiful light blue, enhanced by the Deepsky filter.

  2. Bertrand,

    this is a beautiful sketch!!
    Only a giant dob can give this result with such subject.

  3. A lovely drawing, and fairly accurate. It indicates the observer has some skill in drawing.
    Brightness is, of course, slightly exaggerated, but the overall impression, when using a filter on a 25″ scope, is just about right.
    I’d love to see the artist’s sketch of Abell 70 (hint!)

  4. Beautiful rendition.

    You have managed to give a fantastic amount of depth to the sketch, such take it makes me feel like “if I move my head this way, I should be able to get another angle”. A real 3D feel. Beautiful.
