Hi ASOD! Here’s my sketch of this stunning pair (or trio) of galaxies located in the constellation of Virgo. I stumbled across these galaxies by mistake when I was searching the quasar 3c 273, lucky me!

Best regards, Leo.

NGC1502 and Kemble’s Cascade

NGC1502 and Kemble’s Cascade

This sketch contains the open cluster NGC 1502 and an asterism made up of a 2 1/2° chain of stars that forms a line from the cluster towards the northwest called Kemble’s Cascade. Kemble’s Cascade was so named by the late Walter Scott Houston, who authored Sky and Telescope’s magazine column “Deep Sky Wonders” for decades. Lucian Kemble was the person who sent Houston a description and drawing of the cascade.

Moon at 2 Day Lunation

Moon - 22 March 2015
Moon – 22 March 2015

This sketch is one of the renderings I am doing for the Astro League’s Sketching Award Program. The moon was in Aries as it was setting over the Pacific. I was able to get some of Mare Crisium. This was done at the Haleakala Amateur Astronomers’ site at the summit of Haleakala this past Sunday, March 22. 2015. I viewed it with my C925/CGEM on a pier with a 2″ Swan 40mm EP at 58X.

English:
Hi ASOD, in my country there are not a good average of cloudless nights, and that to say of my city, however the weather of January and February has left draw these sectors of south sky with my binoculars 10×50.

Spanish:
Hola ASOD, en mi país no hay un buen promedio de noches despejadas y que decir de mi ciudad, sin embargo el clima de principio de año me ha dejado dibujar estos 4 sectores del cielo sur con mis binoculares 10×50.

Lunar Crater Gassendi

Crater Gassendi - 31 January 2015
Crater Gassendi – 31 January 2015

Hi all,

tonight I had a look outside and – yeah, no clouds and clear skies.

So I took out the 10″ f/5 truss dobsonian and prepared for lunar sketching: Today the floor-fractured crater Gassendi attracted me and presented nice central peaks and its rimae on its ground.

Telescope: 10″ f/5 Martini Dobsonian

Eyepiece: Skywatcher Planetary 5mm

Date & Time: Jan 31st, 2015 / 1925-2015 CET

Place: home terrace, Dusseldorf region, Germany

Technique: chalk, charcoal and white pastel on black sketching cardbox paper

Hope you like the sketch.

Clear skies!

Venus-Uranus-Mars—Two Conjunctions

Conjunctions of Venus, Mars and Uranus - 11 March 2015
Conjunctions of Venus, Mars and Uranus – 11 March 2015

Object Name (Venus, Mars, Uranus)
Object Type (Planet conjunctions)
Location (Artignosc-sur-Verdon – Provence, France)
Date (11/03/2015)
Media (graphite pencil, watercolour pencils, white watercolour paper, Paint.net)

I always have issue to find Uranus, without GoTo, it’s not so easy…and I don’t like facility…
Thinks are moving in our planet system. It’s why “planetos” in Greek means “vagabond”.
So I use the opportunity of this double conjunction just a week from each other to find Uranus and its so nice colour.
The Venus-Uranus separation was 5.2’ Venus was 10’000 more brilliant than Uranus, while the separation between Mars and Uranus, one week later was 16.25’
The faint K star between Mars and Uranus is HIP 4325 mag=9.5, so no Uranus satellites were visible with my material.

I sketch the two fields on white watercolour paper with inverted method using a chromatic wheel, orange for Venus, blue for Mars and crimson red for Uranus then I just have to invert the two sketches after scanning. The deal is to manage the colour values in inverted mode.

Clear sky to you all, and for some of you I wish you a nice eclipse on Mart 20.
