Sketch and details by Dale Holt
These day virtually all of my deep sky observing is undertaken from my observatory using my 14″ F5 Newtonian coupled with a Watec 120N video camera. I sketch the ‘virtual’ real time image from the black & white monitor display in my office attached to the observatory.
I use an HB pencil, eraser and blending stump on standard cartridge paper. I scan the image and reverse to a negative before storing as a J Peg.
For this drawing of the ‘Blinking Nebula’ NGC 6826 in Cygnus I used a Lumicon UHC filter in front of the camera.
Clear Skies, Dale
