Object: NGC 2997 (GX, Ant)
Date: 06./07. 06. 2013.
UT.: 20h17m – 20h38m
Equipment: 400/1800 Skywatcher Dobsonian-reflector
Mag.: 225x
FOV: 13’
S = 7 / 10 T = 5 / 5
Observer: János Gábor Kernya (Hungary)
Location: Farm Isabis – Red house (Namibia)
Object Name: M74 and SN2013ej
Object Type: galaxy and supernova
Location: Cherry Springs, Pennsylvania
Date: August 5, 2013
Media: graphite pencil, white paper, digitally inverted and scaled
Notes: 16″ Newtonian, 225x. Observed UT 2013-08-05 06:30-08:20. 10 deg. C, 75% humidity. Exceptional transparency, good seeing. Most of the night the transparency was variable, but it became exceptionally good (at least for summer) one hour before astronomical twilight. As M74 was then reaching respectable altitude, it erupted with detail. The very compact HII region Hodge 627 was seen intermittently within the star cloud at the end of the southern arm. Although the exaggerates this brightness difference, supernova 2013ej was indeed brighter than the surrounding Milky Way stars.

Thanks for looking!
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.

Object: Sun
Type: Star
Media: Graphite pencil and white paper

Seeing: good…
Due to Peak of solar cycle, sun has gone very active…. I could make out the burst over 2 hours….

Lunar crater in lower eastern quadrant
Sketched from: Teulon, Manitoba Canada
Date: 21:00 to 22:30 CDT Sept 27th 2012.
Medium Graphite pencil ink and whiteout on white paper. Image flipped and contrast adjusted to compensate for scanning shortcomings.
This was the stunning end of a string of impressive looking craters starting back at Gassendi that night.
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.

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).
