Object Name: Comet C/2012 S1 (ISON)
Object Type: Sun-grazing Comet
Location: Near Grant, AL, USA
Dates: October 8 & 26, November 2 & 11, Before Sunrise
Media: Graphite Pencil on Strathmore Tracing Paper
Equipment: 20″ F/5 Newtonian with 13mm Ethos, 35mm Plossl (Russell Optics), 35mm Deep View (Orion), “Red Light Box” software, i-Pad (for backlighting the tracing paper).

These four sketches show the evolution of Comet ISON over time during October-November 2013. At first, the comet was barely visible. No nucleus or dust tail could be discerned, but over time they became apparent. Each drawing is a stack of individual black and white sketches using the indicated filters. They were edited and stacked using Photofiltre and Canvas software.

Hi Asod! Last night I woke up at 5.00am to observe Comet Lovejoy. I couldn’t see it with naked eye (I think because I observed from city), but it was very bright! I observed it at 90x and 42x and this was the best magnification; nucleus was very compact and more bright than tail. It’s the first comet I’ve ever seen, just wonderful!

Date 02.12.2013
Media graphite pencil, white paper, color invert

We don’t have so many good weather in Poland last weeks. So when I realised that night from 2nd to 3rd of December will be good I decided to wake up early morning to observe comet C2013/R1 Lovejoy. And it was really good observation night. Comet looks great. It is visible even with naked eye. When you use binocular, you can observe really condensed core with delicate tail. With “stronger” telescope you can see the green colour of the comet and bigger part of really long tail.
I used SW 120/600 refracotr with special comet filter Lumicon Swan Band mounted on Meade UWA 8,8mm eyepiece. It is really good filter designed to see details in gasous comets even in weak sky conditions. When you use this filter sky background is really dark and comet shine stongly with high contrast. It is also possible to see delicate structures inside the tail (close to head).
If you dudn’t see this comet, you must try it. It is really worth to observe.
Object Name : C/2012 S1 ISON
Object Type : comet
Location : Béziers, south-west France
Date : November 20 2013
Media : graphite pencil, white paper + PhotoPaint
Comments :
The moon was almost full, the sky was not dark enough, so the tail was shade off and fairly not visible.
Only a bright star could be seen in this area.
The turquoise colour of ISON comet was (R.I.P.) very nice, with a very bright dot as shown on the skectch.
Equipment : 300mm Telescope + 24mm Ultra Wide Angle eyepiece
Sketch was made with pencil on white paper while observing the comet on the road side before sunrise.
A bit of image processing was used to invert the image and give it some colour.
On Friday evening after setting up to observe, I could see sky conditions would be better than average for this time of year( late fall).
When Jupiter climbed to more than 60 degrees above the horizon, I realized that this would be the night to make a first sketch of Jupiter for the season.
The GRS was redder than last season especially in its center and was well set apart from both the South Tropical Zone and South Equatorial Belt. Europa had just emerged from behind the North Tropical Zone on the following side of the planet. A couple of festoons could be clearly seen in the Equatorial Zone emerging from the North Equatorial Belt.
It was right at my tolerable cold temperature limit for sketching and I finished before needing to retreat indoors to warm up.
On a steady night of good seeing this is the time to give Jupiter a look.

pour l’ASOD, je te propose la nébuleuse de “la patte de chat” NGC6334 observée en août 2013 au Chili, désert de l’Atacama au pied du VLT, avec le T400 de voyage en carbone (15kg), ethos 8 et 13mm.
Quasi inexistante sans artifice, elle se révèle sans pareil avec un H-béta, d’où cette idée d’une colorisation L, Rouge (H-béta), Vert (OIII).

Hello
For ASOD, I offer the “Cat Paw” Nebula observed in August 2013 in Chile, the Atacama Desert at the foot of the VLT, with the T400 travel carbon (15kg) NGC6334, 8 and 13mm ethos.
Almost nonexistent without artifice, she reveals unmatched with an H-beta, hence the idea of a coloring L, Red (H-beta), Green (OIII).
