PanSTARRS C/2012 K1 and STF1758

Object Name (PanSTARRS C/2012 K1 and STF1758)
Object Type (Comet and Double Star)
Location (OAB – Observatoire Astronomique de Bauduen)
Date (May 1st, 2014)
Media (graphite pencil, watercolor, white 300gr paper)

Ahhh, this night I really enjoyed myself! Imagine a unlikely place of beauty, the St. Croix lake, with the emerald waters of the “gorges du Verdon” and just above a sky of dream.
Between the two: the Olivier Planchon Observatory located near the nice small village of Bauduen. In the observatory a heavy reflector holding a main mirror of 24″ (620mm) f/d 3.3, a series of brand new Ethos eyepieces and voila.
My pencils show the target of the moment: another comet PanSTARRS, still quite small, but just near the comet a very pretty double star.
My friend “Apilaure” a specialist of double stars, talks about this double:
– It is also called STF1758, a Struve of 1830. The separation was 3.4” in 2010. It is more than likely a physical double because Hipparcos gives the same parallax for A and B, so a distance of 279 light year. The couple turns slowly, 15° in almost 2 centuries.

This is undoubtedly the superb material and this nice double, that I was deprived of the sight of the ion tail, I will return in this observatory, that’s more than sure!

I wish all the best to the ASOD community !

C2013 R1 Lovejoy

Hello ASOD! I present to you one of my sketches – here is a lovely Comet Lovejoy. Info about date, equipment, etc is on it. Sketch created scopeside with pencil and blending stump on white paper while observing this beautiful Comet ~2 hours before sunrise. I hope you enjoy that sketch. Clear Skies!

Comet C2013R1 Lovejoy - December 4, 2013 — Comet C2013R1 Lovejoy – December 4, 2013

Object Name : C/2013 R1 (LOVEJOY)
Object Type : comet
Location : Laprade lake (Aude), south-west France
Date : December 04 2013 4h45 TU
Media : graphite pencil, white paper + PhotoPaint

Comments :
The LOVEJOY coma is bright and light green colour. A darker ring surrounds the shiny nucleus.
The tail is wide and about 10° long. It is rather white.
I saw it easily with binocular 10×50 on the left of Boots constellation.

Condition : A very good and dark night, no moon, no wind, pretty good seeing.
I could report mag 7 to 12 starfield.
No significative named star in the field.

Equipment : 300mm Dobson Telescope + 24mm Ultra Wide Angle eyepiece (mag X64 FOV 1.3°)
Sketch was made with pencil on white paper while observing the comet before sunrise (-2°C)
A bit of image processing was used to invert the image and give it some colour.

A Bay Between Tails

C/1995 O1 (Hale-Bopp) - February 15, 1997 — C/1995 O1 (Hale-Bopp) – February 15, 1997

Hey ASOD!

This time I send again a sketch of the unforgetable great comet Hale-Bopp!
The observation was made the time before the fine spiral-bows appeared.
There was a bay of almost dark sky between the two tails.
C/ Hale-Bopp was the finest comet I have seen, and longlasting on the northern sky,
with many fine structures to observe in the inner coma.
I used color-crayons on black paper. Info on my sketch.
Location: Trondheim, Norway.

This year I celebrate 50 years as an amateur-astronomer (65 years old),
and have 330 sketches total!

Thank you for your comments and HAPPY NEW YEAR
from Per-Jonny Bremseth.

C/2013 R1 (Lovejoy) – December 4, 2013

Hey ASOD!

This time I send a sketch of comet LOVEJOY from todays morning.
The observation was made with 166x magn. on my telescope.
The comet is a really nice one with both binos and telescope!
Info on my sketch.
I used graphite pencil on white paper and inverted in color.
Location : Trondheim, Norway.

Clear sky to all of you from Per-Jonny Bremseth.

Comet ISON: Incoming

Comet C/2012 S1 (ISON) - October-November, 2013 — Comet C/2012 S1 (ISON) – October-November, 2013

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).
Weather: Excellent Transparency and Seeing on all dates.

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.

C/2013 R1 (Lovejoy) – December 4, 2013

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!

Meeting with a Green Comet

C2013/R1 (Lovejoy) - December 2, 2013 — C2013/R1 (Lovejoy) – December 2, 2013

Hi,

In attachment you can find sketch of comet C2013/R1 Lovejoy

Short description:

Object Name C2013/R1 Lovejoy
Object Type comet
Location Budy Dłutowskie – small village in central Poland
Date 02.12.2013
Media graphite pencil, white paper, color invert
Telescope Sky Watcher refractor 120/600 + Meade 8,8mm + Lumicon Swan Band
Seeing 2/5 (good)
Transparency 2/5 (good)
NELM 5,4 mag

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.

C/2013 R1 (Lovejoy) – December 3, 2013

Hello sketchers,

Object Name (C/2013 R1 – Lovejoy)

Object Type (comet)
Location (Provence France)
Date (3/12/2013)
Media (watercolor on paper 65cm/25cm)

This very morning, early, from Néoules, a nice dark sky area, I made 5 sketches with :
a 80/400mm refractor (10x) for the large field and the long tail,
a Dobson 12”, 58x and 150x for the coma around the nucleus
and a 102/1000 refractor (25x and 100x) for the intermediate view.
I used miscellaneous EP from 40mm to 10mm Delos, sometime with UHC filter.
I made this watercolor today 3 December at home, the idea was to put together the different magnifications on a single view.
Oh yes, something funny, to sketch the tail, I used a light sand paper to take away the pigment from place to place; this sand feels like real comet dust : scale 1/1…

Clear sky to you all !

Bonjour,

Voici un dessin de la comète Lovejoy, réaliser avec un dobson de 345mm et un oculaire de 40mm (grossissement 37 fois).

Elle est sublime ! Le noyau très ponctuel et bien brillant. La queue est large et fait au moins 2° de long.

Le ciel était stable.

Fait à Fayssac dans le sud de la France le 28 novembre 2013 à 5h20 Local. Club d’astronomie APAM.

Hello,

Here is a drawing of comet Lovejoy, achieved with a dobson of 345mm and a 40mm eyepiece (magnification 37 times).

It is sublime! Very punctual and very bright nucleus. The tail is made wide and at least 2° long.

The sky was stable.
