Alpha Librae and Jupiter through binoculars

This year I started working on the Astromical League's Binocular Double Star Observing Program. I hope to complete this list, including sketches, within a year or two. Its about 120 double's so that should be something nice to try with my 10x70 and 15x80.

Here is a sketch of one of them, Alpha Libra, together with Jupiter and three of its moons. The sketch was made on the 7th of May 2018, at 2.20 local time. South is up, and east is to the left. Alpha Librae is the double star near the rim on the right. Jupiter is visible with Callisto, Io an Europe. Ganymede is to close to Jupiter to be split with the Fujinon 10x70. The yellowish star to the southeast of Jupiter is Nu Librae. You only can get these beautiful wide angle fields in binoculars. The Fujinon 10x70 has a 5.3 degree field of view.


Astrodessin: Observing and sketching of astronomy objects

A few months ago I bought a publication from Axilone-Astronomie with the title "ASTRODESSIN, Observation & dessin en astronomie" This double volume is in my opinion the best book around about sketching at the eyepiece. It is in french, but with a dictionary it is possible to understand most of the text. But a large part of both books is packed with sketches, and that is an international language for amateur astronomers! All of the sketches, made by different contributors to the book, are of a high quality. You will find the Sun, Moon, Comets, Eclipses, Planets and all different types of deepsky objects/. The book is large (A4+) and the print quality is excellent. A truly awesome and inspiring book, that shows how beautiful observing at the eyepiece is. Nothing reflects visual astronomy and the experience at the eyepiece better than a sketch. Highly recommended..... well done guys!




Updated sketch of Stephenson 1

At the moment I am trying out new methods for digital processing of my sketches. The sketch below, of Stephenson 1, an open cluster in Lyra, is based on an observation I did a few years ago. I do all my sketches in pencil and on white paper, scan them into Photoshop, and proces them. The method I use is based on several different manuals from fellow astronomers who sketch at the eyepiece, but mostly on Peter Vercauteren's manual (http://www.astronomydrawings.com for Peter's website) and Jeremy Perez's manual ( http://www.perezmedia.net/beltofvenus/ ). The beautiful sketches of these guys are an inspiration for me!
