The Iris Nebula

NGC 7023, a reflection nebula in the constellation Cepheus
NGC 7023, a reflection nebula in the constellation Cepheus

Hi community ASOD, in holidays past summer I had the opportunity to travel to a great place with black skies. A goal Iris nebula in the constellation Cepheus. Easily detected at low power and lose contrast and light passing 100x. The star of magnitude about 7 something brighter northern main oval, followed by gaseous envelope that covers most of extension. In the south 2 star within the gas cloud, leading to the isosceles triangle with the brightest star. A magnificent object late summer.

Best Regards.
Roberto.

Bailly Crater and Region

Lunar crater Bailly and environs - August 9, 2014
Lunar crater Bailly and environs – August 9, 2014

Hi,

Please accept my submission of Baily crater and surrounding region. The weather was very nice that night; warm and dry and the seeing was excellent. The Moon’s liberation was favorable to bring Bailly just past the terminator. I made this sketch using my 10” Discovery Dobsonian telescope at a magnification of 170x with neutral filter.

Object Name: Bailly crater and region.
Object Type: Lunar Crater
Location: My backyard in Green Bay, WI, USA
Date: 8/9/2014 2:00 UTC
Media: mechanical graphite pencils (2H, HB, 2B, 4B), white paper and blending stumps

Thank you,

Brian Chopp

Conjunction over an Italian town skyline

Conjunction of Venus and Jupiter - August 18, 2014
Conjunction of Venus and Jupiter – August 18, 2014

Object Name– Venus, Jupiter
Object Type Conjunction of planets
Location Pesaro, Italy
Date 18th August 2014

I woke up early at 5:00 o’clock to take a look at this marvelous conjunction. It was still night at the time and I was surprised with a mighty view of the rising Orion. I waited on my balcony for until the planets were visible over the roofs in front me. I quickly took my pencil and drew what I saw on the eyepiece of telescope, but the seeing was awful and just two moons were visible. The view of this two small lights dancing together over the roof in the cold morning was much more intriguing, so I tried to sketch the whole landscape. Never tried this kind of astronomy sketch before, probably my first landscape since I was a child.

Messier 57, The Ring Nebula

Messier 57, The Ring Nebula

Object Name – Messier 57, The Ring Nebula
Object Type – Planetary Nebula
Location – Tullamore, Co. Offaly, Ireland
Date – 06 August 2014
Media – Graphite pencil on white paper (Image inverted)

This is my first sketch of M57. Observations were made using an Orion XT10i and a 17mm Wide Angle (65° FOV) lens.

The seeing conditions were average, however i made the sketch from my back garden under light polluted skies. There was also a half moon present which added to the skyglow.

I used averted vision to notice the subtle features of the slightly elongated nebula. The central star was not seen in my telescope.
Observations were made with and without a DMC Narrow Band Pass Nebula filter. The filter slightly increased the contrast of the nebula while obscuring the background stars.
Overall I am very happy with how it came out.

I would like to show, through this drawing, how the seeing is important to observe and describe very little objects.

Object: NGC 1999
Object type: reflection nebula and globule
Constellation: Ori
Date of observation: 2011 10 01
Length of observation: 60 min
Height of object above horizon: 28.5°
Observing site: Observatoire des Baronnies Provençales (Southern French Alps)
Observing conditions; exceptionally good, mag limit 6.7v, SQM 21.50, FWMH 0.9” !!!
Instrument: Dobson Obsession 25”
Eypiece: Ethos 6mm, without filter, power 520x

Notes: I am astonished: at the eyepiece, I have in front of me a delta winged aircraft, perfectly clean. Extremities of wings are curved, the “head” of the craft easely detailleable. The encreasing of bright nebulosities around the head and at the back of the wings have also been noticed.
The caracteristic blue color of reflection nebulae is obvious.
