Made through my 254mm reflector with 25mm EP and 2.5 barlow lens.

Object: Comet (C/2012 K1 Panstarrs)
Date: May 27, 2014
Location: Aguila, Arizona USA
Medium: Digital, iPhone – The following apps were used to render the sketch; Sketchbook Mobile, Juxtaposer, Paint FX & eZY Watermark.
Instruments: Binoculars- Orion 25×100 and Celestron 8×56 with a FoV of 2.5 degrees and 5.8 degrees respectively.
Magnitude: 8.5
Weather: One cannot ask for a better night than, 75 degrees F and no winds! A superb clear and dark sky with an average read out of 21.6 mag/arcsec^2.
Comments:
The comet is not a naked eye object just yet. However, with the help of a good dark site, averted vision and my 8×56 binos, you can detect “her fuzziness” among the stars. My guiding or go-to star was 52Psi UMa. Below or to the west of 52Psi UMa, are three stars of almost equal magnitude. Within those stars, there appeared the the dirty chunk of sublimating matter. No other physical characteristics were noticed using the 8×56 binoculars except to spot the fuzzy traveler.
Wohoo, we have a tail! That’s what the 25×100 will reveal. Yes, the coma and false nucleus become evident along with the dust tail. Dim but noticeable is the dust tail that is somewhat broad and undefined, extending towards the east. I would calculate it to be about 1/3rd of a degree in length. Glowing at magnitude 8.5 according to some sources, comet Panstarrs also, showed a faint stellar nucleus. I gave an estimate to its degree of condensation to be between 4 and 5. I tried to look for any greenish hue but none was noticed. Panstarrs C/2012 K1 is a tenuous comet that’s a challenge to observe but, will give us some more and better opportunities as the months progress.
About the sketch- I’d like to add that digital sketching is not a scopeside skill that I have mastered. I made many attempts to plot the starfield of the binoculars with no success. The repetitive task of looking back and forth between iPhone and binoculars killed my dark adapted eyes.The iPhone is very bright even when the screen brightness is vastly decreased. So the next logical steps was to take all information on paper, plus make mental notes of all and any pertinent physical traits. Once that was done, I went ahead back to the iPhone like a champ and put all that info to visualization. Enjoy!
Clear and Dark Skies,

Average seeing and transparency occurred during the entire observation time.
I was using a 6 mm eyepiece to get the magnification up to 241x.
The color version was made indoors after the graphite eyepiece sketch.
The north polar cap was small and clearly visible. Mare Acidalium appeared very dark and Niliacus Lacus appeared somewhat darker than during my observation one week ago. Sinus Meridiani, Sinus Sabaeus and Margaritifer Sinus were all clearly visible. Clouds were visible over Aeria and the parts of Syrtis Major just visible at the preceding limb. Clouds also covered Tharsis.
Equipment and Sketching:
This is an eyepiece sketch made with a HB graphite pencil, blending stumps, White Pearl eraser on white sketching paper and assorted colored pencils.

Object Name: Messier 5
Object Type: Globular cluster
Location: Deventer, The Netherlands
Date: June 2, 2014
Media: White pastel and white gel pen on black paper
This time of year the sun never drops low enough under the horizon for
true astronomical darkness. Only after midnight we get a few hours of
relatively dark skies, but a faint blue glow always remains visible
above the northern horizon. However, bright objects can still be very
impressive in the eyepiece. Messier 5 is a fine example: a very bright
ball of stars, loosely scattered amidst a few dozen foreground stars.
When I made this sketch, the sun was only 12 degrees below the horizon.
What is very striking visually is the off-center core of M5. The
brightest part seems to be slightly to the west of the cluster.
I made the sketch using a white gel pen for the stars and a white soft
pastel pencil for the glow of unresolved stars. It was the first time I
made a positive deepsky sketch, normally I use graphite on white paper.
The image is the original field sketch.
Clear skies!

A large prominence on Sun’s SE limb 1st June 2014. Hard to imagine that these glowing clouds are cooler hydrogen gas surrounded by hotter transparent plasma. Sketched at the eyepiece with Derwent Watercolour pencils on black paper. SolarMax60 H-Alpha ‘scope 50-80X. Location UK.
Hello ASOD! I sketched this planetary nebula (also known as M27) on 11 August 2013 with my dobsonian telescope. I used also as eyepiece WA 12mm that gave me a magnification of 104x. It’ s a very big nebula; thanks to my UHC filter, I was able to observe its structure: fantastic!

Hi everyone!
I observed M78 &34 in Nov. midnight with my 15″ Dob.
While I drew M78, I reminded of tropical fish, it’s side face 🙂
The nebulousity of NGC 2071 is shine dimly.
Where does this tropical fish came from?
Deep cosmos? Deep see? or My eyes? 🙂

Object Type : Reflection Nebula

Jupiter was almost directly at zenith and very bright. It was also located directly atop the star Gemini Delta. I could spot all four Galilean moons easily through my binoculars. Towards the end of this sketch, a heavy mist/fog rolled in, diffusing my view…
