Gassendi at Terminator

Lunar crater Gassendi - October 4, 2014 — Lunar crater Gassendi – October 4, 2014

Object Name: Gassendi
Object Type: Lunar Crater
Location: Dunboyne Ireland
Date: 4th October 2014
Media: Graphite pencil H2, H3 & B6 with standard white stock and technical drawing equipment.

This is actually sketched as observed through the eyepiece with a 15mm on a 9.25 SCT rather than from the phone screen. The seeing was fair but a weather front was fast approaching and just managed to observe long enough to capture this detail. At the same time I took some snapshots through the eyepiece with my smartphone for a smartphone astronomy site – so got to do both before the clouds rolled in. Adding the phone to the sketch allows me to add a technical drawing into the mix which I not (only) enjoy but also allows me to capture the evenings activities and optical equipment used during the session.

Many Thanks

Cheeseburger Anyone?

NGC 7026, "The Cheeseburger Nebula", a planetary nebula in the constellation Cygnus — NGC 7026, “The Cheeseburger Nebula”, a planetary nebula in the constellation Cygnus

Hi,

This is my sketch of the Cheesburger Nebula, NGC 7026, a Planetary Nebula in Cygnus. I did the sketch in my Orleans, Ontario backyard using graphite on white paper on Sept 23, 2014, a night of great seeing. It was cleaned up and inverted in Paint Shop Pro. The nebula is quite small, fairly bright with two diffuse nuclei and a hint of darkness between them. Even at 300x in my 12 inch dob I couldn’t confirm if the Cheeseburger has a pickle!

Clear skies,

Gordon

Rupes Recta on the Moon

Rupes Recta, "The Straight Wall", a linear fault - March 15, 2008 — Rupes Recta, “The Straight Wall”, a linear fault – March 15, 2008

Object Name: Rupes Recta on the Moon
Object Type: Moon crater
Location: Chiba Japan
Date: 2008/3/15
Media Black graphite pencil on a white paper. Contrast adjusted with PC.

Equipments:: Telescope: Televue 85, Eyepiece: Pentax XW-10 with Power mate 2.5x

After outlining major features using solid lines, dotted lines and numbers(1-9) are used to express gradation in brightness(right). The numbers are replaced with “real” darkness after the lines are copied on another paper (left).

Thanks.

Mooncrater – Wilhelm

Lunar crater Wilhelm - October 3, 2014 — Lunar crater Wilhelm – October 3, 2014

Hello,

last week (October, 3rd, 2014) I met my astro-friend Ralf Mündlein in his nice observatory. In his 5m dome with 16″ ACF and 8″ Apo we started our observation. First object in this night was the moon. The air was excellent and we were very happy to have such great impressions on our cosmical neightbour.

A chose the nice crater Wilhelm with some bigger impacts around the craterwall. A fine mountain chain at the bottom of the crater took my attention. So I made a drawing of this crater with the 8″ Apochromat. It was hard work, because there were so many details. I needed nearly one hour to catch the whole crater.

Two Big Prominences on the Edge

Two large solar prominences on the limb - October 4, 2014 — Two large solar prominences on the limb – October 4, 2014

Object Name: Sun
Object Type: Solar prominence
Location: Deventer, The Netherlands
Date: October 4, 2014
Media: pastel pencils on black paper

As the days shorten rapidly and the sun gets more south every day, the warm afternoons are coming to an end in the Netherlands. On what could be the last sunny and warm day of the year, the active Sun was the obvious target for an astronomical sketch. I set up my modded 60mm Unitron/Polarex refractor and sketched two large prominences on the western edge of the solar disk. The prominences were of the “stable” and relatively long lasting type, but still a lot of internal swirling and changes in brightness could be seen in both at high magnifications. Due to seeing conditions magnifications were limited to about 80x-100x. I made two separate sketches, but got the idea of combining them in a composition when photographing them afterwards.

Kind regards,
Roel Weijenberg

NGC 7293 Helix Nebula

NGC 7293, "The Helix Nebula" a planetary nebula located in the constellation Aquarius — NGC 7293, “The Helix Nebula” a planetary nebula located in the constellation Aquarius

Hi,

After 4 years of “try & error” with a faint NGC 7293 in the horizon haze of central Europe I finally finished “my Helix”, using the 24” Dobson at Hakos Guestfarm in Namibia. No haze, but 70 degrees high in the sky, the Helix was an impressive beacon, details were easy to report. I wasn’t prepared to see the halo, my template was too small to sketch it, so I had to use a second sheet. Seeing was moderate, I didn’t see the faint background galaxy 2MASX, but… nevertheless I enjoyed it!

Data:
Object Name: NGC 7293, the Helix Nebula
Object type: Planetary Nebula
Location: Hakos Guestfarm, Namib Naukluft, Namibia
Date: June 4th, 2014 (about 2 hours total of sketching)
Media: Pastel and graphite pencils
Optics: 24” Dobson f 4.0
Filter: OIII

Additional aspects:
Field is about 30’ wide, east is up. To concentrate on object (and not on dimensions) I used a pattern of stars printed from Guide 9 as a template. Pinpoint stars added by image processing software (to replace printed and sketched stars)

Spots AR2171 and AR2172 Solar

Active regions AR 2171 and AR 2172 - September 27, 2014 — Active regions AR 2171 and AR 2172 – September 27, 2014

Hello,

As soon as I put the eye in the ocular of the glasses, my heart skipped a beat(I saw red)! That the Solar surface is magnificently stained!

I decide to crunch(outline) one of the spots (who(which) I ignore N at the time of the drawing), the 2172, telling me that the task is already very sufficient(self-important) seen the scale of details.

Once ended, of small spots in small spots, I decide shyly to widen the frame(executive) in 2171.

The twilights of the main spots appear finely chiselled on their outlines when the turbulence calms down in a regular way.

Finally, at the end of 2 big hours of observation stuck on the ocular, and the aching loins, all the spots situated downward the Solar surface is there! I thought not at all of arriving there at this stage(stadium) from the first moments.

Whrite 12 at 14 h UT – 27/09/2014

– Drawing makes for the criterium HB
– 2 working hours behind the ocular to realize the drawing.

Bye.

H alpha Sun sketch

Active regions, prominences, sunspots and plages on the Sun - September 28, 2014 — Active regions, prominences, sunspots and plages on the Sun – September 28, 2014

Object Name Sun
Object Type H alpha with PST, XW-10
Location Tokyo japan
Date 2014/9/28
Media Black/red pencils on a white paper. Contrast adjusted with PC.

This my first submission to the site. I hope it is acceptable.
An M-class flare has erupterd at #2172 about one hour after this sketch. I could already see some active regions between the two sun spots.

Thanks.
