Omega Centauri (ngc 5139)

[Raul Leon]

Omega Centauri is a globular cluster in Centaurus; magnitude:3.5 ;size:36.3' ; brightest and largest of all globs; best view ever on a night of good seeing, this huge star sphere is amazing in all telescopes, although not very high up in my sky, it was exceptional on this particular night, hundreds of thousands stars sparkle in and out of resolution. There are two areas that appear to be starless voids named the footprint, which was also observed. I used my 14.5 Starstructure Dob f/4.3 and a 21mm Ethos eyepiece . 75x magnification https://thestarsketcher.blogspot.com/

I am new to this forum and wanted to comment on this magnificent sketch. This is one of my favorite objects to observe. I am always hoping to see the footprint in this object. So happy to see how well you captured this.

Hi All,

Here is my sketch of this globular, made from Tivoli, Namibia, through a 20" obsession

Bertrand , although your electronically processed Image looks aesthetically perfect, I have a problem calling this a sketch . No disrespect, But did you have your computer at the eyepiece? The light from your Monitor alone would ruin your night vision. Raul

Hi Raul,

In spite you think, this is a sketch and not an image. Here are some steps of the making of the drawing.
Of course, I've not pointed each star at the eye piece with a pencil, but I've attempted to make a sketch which represents, at least according to my eyes and mind, the most representative vision I saw at the eyepiece.
This is always the purpose of all my drawings: to draw what I saw, all what I saw, and nothing more that I saw

Bertrand, Thank you for your response, but I have one last question. How do you remember what you saw if you don’t do these at the eyepiece ? Raul
