Orion’s belt stars

Hello ASOD, here join my last watercolor

Object Name (Orion’s belt stars and M42)
Object Type (Constellation and nebulae)
Location (Porquerolles on board of Aquarellia)
Date (02-10-2013)
Media (watercolor on white paper, paint.net for inverting the sky)

In the night of October the first, our old two masts Aquarellia was anchoring close to the harbour of Porquerolles, one of the three “Provencal golden islands”.
At one o’clock in the night I wake me up,… maybe ‘cause of some wave noise? I was surprised by seeing the Orion’s belt stars and M42 rising close to the ‘Sainte Agathe’ fort. With my 7×50 binoculars I sketch this original encounter, the mythic Orion warrior at the rear of a real castle.
The French coast, here in my nord, is full of light pollution but to my surprise, the castle illumination was the only light in the sight. The island is not so close to the polluted coast, so the Orion’s constellation was pure in the dark while rising.
This watercolour was made on board with local salt water (;

I hope you enjoy

The Whispy Veil

This is a sketch of NGC 6960, part of the Veil Nebula. Originally sketched on white paper, reversed and processed in Gimp 2. This is my second time doing this method, and I am pleased with the results.

Scope: Criterion RV-6
Ocular: GSO 32mm Plossl + Celestron.
UHC
Location: Prescott, AZ

Thanks for looking!

Little Gem Nebula – NGC 6818

NGC 6818, also known as the Little Gem Nebula, is a small but bright planetary in Sagittarius. It is one of my favorite summer objects because of its annular structure, which is not difficult to see even with my small telescope. The best view comes at 222x with an UHC filter, that makes its ring shape easier to spot. Curiously, it seems that the central dark region is not exactly in the center but slightly off to the north, and the ring is brighter in its southern half. At low powers the nebula shows a lovely greenish-blue color, which is typical of many bright planetaries.

Facets of the Dolphin

Dolphin Constellation

several objects

Location: The Bullaque – Ciudad Real – Spain

Date: 2013 – September – 01

Media: Graphite Pencil HB, torchon drawing sheet 1 and 130g

Inverted colors with GIMP 2.8

The Dolphin is a summer constellation modest, but can be very interesting for the amateur observer. Spend an evening full observation of its four most significant objects two planetary nebulae and two globular clusters, has been very rewarding.

When observed at the same time, are more striking differences between the two planets:
NGC 6905 is sees as a small disk, very bright and is easily distinguished in the field, and
NGC 6891 is quite the opposite, very small, very bright and compact, ie stellar appearance, difficult to distinguish from the other stars in the field.

The two globular clusters are very different concentration among them, but the different distances from us makes visual texture is very similar:
NGC 6934 (Class VII and 50,000.) Is bright, large, round, with denser center, feathered edges and mottled texture, and
NGC 7006 (Class I and 150,000 al.) Is less bright, somewhat smaller, round, with denser center, feathered edges and mottled texture.
A sample of observation is the sketch I made (picture above).

Finding NGC 6891 has been a challenge, stellar appearance has remained up to 200x and only from the 220x has started to show a very small round and compact disc.
The UHC filter and averted vision were needed in the localization and subsequent observation of nebulae.
For all objects have the best view obtained with the 220x. Good quality of the sky with a 21.41 SQM (roughly Male zone 6 was 6.2).

The Crab

Type: Supernova remnant, diffuse nebula

Location: Gardner, CO; 37º50’N 105º11’W

Orion Nebula from the Black Forest

Hello,

This is my sketch of the orion nebula, drawn on September, 5th 2013, 4:30h at Kaltenbronn Hohloh, black forest, germany, at 998m with my 18″ Dobson Telescope at 135x using an UHC filter.
Height: 18 degrees over Horizon

Drawn with pencil on white paper, scanned, inverted, and processed to remove “dust-stars” from scanning, darkened, and used the smudge tool to recreate the filaments in the nebula.

Kind regards,

Arndt Schädler

Blue Flash Nebula

On 31 July, we had the best observation conditions. The air was as good as ever before. At the beginning of the night I was looking for the Blue Flash Nebula NGC 6905.
At low magnification, the bright trapezoid fit into the field of view and the pretty star chain that led to the fog was beautiful to see.

The night was wonderful and I could look at many beauties of heaven. The transparency was excellent and everything in warm temperatures and little wind.

Object: NGC 6905 “Blue Flash Nebula”
Telescope: 10 “ACF
Eyepiece 31mm Nagler
Magnification: approx 80x
Location: near Tauberbischofsheim Germany

The Trifid Nebula

Object: 20 Trifid Nebula
Location: Mt. Nerone
Date 3rd Aug 2013
Pencil on white paper

This nebula is quite low at my latitude and thus is always submerged in the light pollution halo from cities in the south. This makes it a quite difficult object without a nebula filter. I have obtained the best results with an UHC-S filter. I also tried with an OIII filters which gives outstanding constrast on Lagoon Nebula, which is just nearby, but it is not the best for the trifid.

Messier 20 and 21

Did some observing and sketching in the Sagitarius region on 8/24/2013. Very “crowded” area of the sky … so much to see and sketch. What caught my eye was the view of M20/M21, both easily visible in the FOV of my rich field scope. Hope I did it justice.
