Little Gem Nebula – NGC 6818

NGC 6818
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.

This was the stunning end of a string of impressive looking craters starting back at Gassendi that night.

H-Alpha Sun – August 22-31, 2013

Location : Castres, south-west France (near Toulouse)
Date : from 22 to 31 august 2013
Media : graphite pencil, white paper

Comments :
Dayly sketch of sun made through a small Coronado PST (H Alpha) + 15mm Televue eyepiece
Method :
1) dayly observing sun coronado around 12h TU
2) quick sketch with ballpen on paper notepad (2 minutes)
3) later copy out on drawing paper with graphite pencil (10 to 12 minutes)
4) picture take of each drawing with camera + Photoshop processing
– flipping horizontally and vertically in order to see the correct sun orientation
– grouping the 9 pictures + date on the same sheet
One may see the sun rotation from August 26 to 29 watching at spots.
I saw some material projections ejected into space (see August 30)
We currently have a great solar activity
To see the solar prominences evolution one should have to observe every hour !

Thank you for taking into consideration this small contribution
Best regards.

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).

From Zucchius to Schiller

Zucchius, Schiller and environs

On the evening of September 16, 2013, I got the best view of the basin ring segment between young crater Zucchius (65 km.) and just the tip of large older crater Schiller (179 km.) The ring arc was more than a day beyond the terminator but perfectly illuminated to show its depth and smoothness.
Craters Weigel (36 km.) and Weigel B (37 km.) initially caught my eye as light was brightly glinting off the rims.
For an excellent image of this region see the LPOD for May 26, 2013

There were many fine crater showing nicely in this region at the time of the observation and sketch.
Sketching:
For this sketch I used: black Canson paper 9″x 10″, white and black Conte’
pastel pencils , and Conte’crayons, a blending stump, Pink and White Pearl erasers. Brightness was not altered but contrast was increased +3 using the scanner for this sketch
Telescope: 10 inch f/ 5.7 Dobsonian with 6mm (241x) eyepiece

The Gigantic Face on the Yura Mountain Range

Yura Mountain Range
Yura Mountain Range

Although recently I have very much interested in Lunar horizon landscpe observation, and also it is a serious hard work that need preparationes, concentrations, patiences to acquire the most valuable results that nobody has seen yet .

So , for me, Lunar horizon observation time is limited , as a or two months of winter season in a year.

Then, other seasons, I useally observe others.

With a fairly good optics [like mine or better…], anyone can find out enormous amount of details on the face of the moon [also on the limb].

One night, very accidentally, I had just seen a much interesting feature in the binocular eyepieces attatched on my faithful 8 inches refractor on along the Yura Mountains range [= Montes Yuras ] , which very resembance to a human’s face … a giant’s face… !! . I was instantlly surprised at the view …. !!!

It’s real dimension , I measured from the diameter of 100 km Plato , must be about within 20 km in length.

Among the many moon sketches of mine , in which shows many curious, grotesque features.. and this gigantic human face is one of that.

Unfortunatelly, by interuption of front roof top, observing time is limited only as 15 minutes, that limits more details on this sktch.
