Hi! Asod, few days ago I saw the nebula California, was very curious to know if I could capture something visual light as they claim is faint. With my little scope locate ξ (xi) menkib, but looking even more side vision was getting nowhere, I knew I needed to filter, but had to try. By putting the filter magically appears, still not something brilliant, but do not strain your eyes because it is obvious that this is no, there is a dark area that crosses na nebula, but with side vision greatly improves contrast. The truth that I could not resist doing a sketch but as always with a very dim light, if you can not have problems adjusting to the darkness.
You only need a dark sky, wide field and nebular filter.
Regards.

Thanks Diego, for your comments.
My apologies sent the wrong sketch, had prepared one with smaller size and English-language writing.
Regards.
Terrific job on this nebula!
