Our Sun in White Light – May 19, 2013

White Light Sun - May 19, 2013
White Light Sun – May 19, 2013

Hello astronomers,

This is my drawing of the sun in white light at May 19, 2013.

Object name: Sun
Object type: Star
Location: Koudekerke, Netherlands
Date: May 19, 2013
Media: Graphite pencils and processed with GIMP
Time: Around 14:00 UT
Telescope: Sky-watcher refractor (102/500mm)

First I made a fussy grey background for the sun and drew a circle. Thereafter I drawed the sunspots and the rest of the details inside the disk. I scanned the picture and processed it with GIMP for a smooth contrast and brightness.

Kind regards,
Lennart van Sluijs

NGC 6337 Revisited

NGC 6337
NGC 6337

Hello again! This time i sketched NGC 6337 from the rural skies of Doyle (160km away) at a star party. Luckily the central asterism (http://www.capella-observatory.com/images/PNs/NGC6337Small.jpg) appeared so much better and no filter was needed for the nebula. I used also a bunch of different eyepieces for the challenge.

Object Name: NGC 6337.
Object Type: Planetary Nebula. Apparent mag. ~12.3.
Location: Doyle, Buenos Aires Argentina.
Date: 12/05/2013 3:00-4:00 AM.
Media: Digital tools. PS 5.

Telescope: Dobson 12″ F/5.

Eyepieces: ES 11mm 82º, BST Explorer 8mm/5mm, TMB II Planetary 5mm/4mm.

Filter: No filter needed (yay!).

Bortle Scale: 3, Rural Sky. Very good transparency, average seeing.

Thank you again!!

M64 – A Different View

Messier 64
Messier 64

M64 -Black Eye Galaxy

Object Type: Galaxy

Location: Tarragona – Spain

When I watched M64 for the first time with my 5″ SC, I thought I was whatching an awesome galaxy. But on the night of May 11, I could see how important telescope aperture and dark skies really are. The image with my 9,25″ SC was very impressive. I attach the sketches in order to compare the two nights. Really, both have their own charm.

White Light and H-Alpha Sun from Polaris Observatory

White Light Sun - February 18, 2012
White Light Sun – February 18, 2012

Dear Asod,

I send you hereby my sketch made this Saturday at Polaris Observatory, Hungary. I used a 114/900 Skywatcher with Baader solar filter for white light sketch and a Lunt 35 for the H-alpha sketch.
The most intersting part is a solar prominence on the northern edge, which is was a very 3D something, biting in the sun-disk.

Equipments used: 114/900 SW (100x) & Lunt 35/400 H-alpha
Date: 18th February 2012, UT: 10:40 (white light) and 11:20 (H-alpha)
Place: Hungary, Budapest, Polaris Observatory
Media: graphite pencil used on white paper

Clear skies,
Judit
