Hi folks,

recently a had some fine night, with good transparency - NELM around fst 7m0, seeing was okay but not very good.

I´d like to share two of my favorite sketches i made this night.

North is at bottom.

2524

2525




Some words to NGC 4536 (first pic, upmost galaxy): the spiral structure upper right (two parallel streaks) is just to understand that way, that there are kind of two separate brightenings. But orientation of this is just out of my memory - not sketched in the field. I just added it according two my notes "two streaks?" with reference to the upper right spiral arm.

Dustlane at bottom of NGC 4527 was visible as moderate but obvious edge.

Looking forward to your comments!

I agree, both sketches are marvelous Norman, and the amount of detail you saw your 12 inch scope is impressive. Are you sketching on black paper, or are these pencil sketches that are reversed?

Hi Howard,

thank you very much for your nice feedback :-)

It´s pencil on white paper, photographed (not scanned) and inverted afterwards. And then a little bit of processing at the stars in PS.

CS!
