The Foot of the Cross

Acrux
Acrux

On April first at 23:00 hs. in La Matanza, Buenos Aires, Argentina, I sketched Acrux, the brightest star in the constellation called “Southern Cross”, “Crux”, etc. This star is also known, in religious terms, as The Foot of the Cross, due to obvious location reasons.

It’s a nice double-star system done in white paper, with graphite 4B, 2B and HB2 pencils; after edited with Photoshop tool, while observing with a Newtonian SW 150/750 f5 telescope.

I liked the final results, so hope you like it too!

It’s a triple sketch, staring Minkar, Regulus and Mimosa (from left to right), all of them stars.

Media: Graphite pencil, white paper, Photoshop.

Seeing didn’t help at all, but anyway, it took me a while to finish the sketchs; the original idea was to draw at least six different stars from different constellations, but right after finishing Regulus, clouds came out to stop my work.

As a result, these are the three sketched stars. Hope you enjoy it!

Hi Asod! My sketch is about a triple and a double stars, in the same field. The triple is STRUVE 2816 and the double STRUVE 2819 and they are both part of the wide open cluster “Trumpler 37″ in Cepheus. I observed the two multiple systems with my Dobson 10” f/5 with a 14mm eyepiece, 82° for a 180x magnification. The observation is great!

Hi everyone,
In a slighly cloudy evening on 18th September, searching holes through the clouds, I have been able to observe one of most famous double star Albireo or beta Cygni. The seeing was very good and giving me a stationary image.
I have wanted o make a sketch of this spectacular object and its amazing colour contrast.
I hope you like it.
Bye.
