Flaming Star Nebula

C31 IC 405 Flaing Star Nebulawordssmaller

Aloha,

IC 405, Caldwell 31 or the Flaming Star Nebula is an emission/reflection nebula that requires darkness and patience to pull details out. A 12.5” reflector was used here to observe and a NPB filter from DMG optics helpful. I observed & sketched the same object 3 years ago and didn’t see the details visible this time around. I would partly account this to gaining greater ability from sketching the object again with more patience this time around.

Proper motion studies of AE Auriga show it to be an ejected star from the Orion Belt region. Its chance passage through this nebulous region of gas & dust give it a “Flaming Star” appearance.

The Witch Head Nebula

Winter arrives, and with it, all the Orion wide field.
Therefore, it’s time for me to propose a drawing of an elusive object of that region: Witch’s Head Nebula, IC 2118.

This observation spent on 3 nights, for an amount of a bit more of 6 hours !
Here are my observing notes:

IC 2118, aka NGC 1909
dates of observation: 8, 9, & 13 02 2013
site: Observatoire des Baronnies Provençales, southern french Alps (www.obs-bp.com)

observing conditions: naked eye visual magnitude 6.6 on UMi, SQML 21.50 to 21.57 at zenith
Instrument: Dobson Obsession 25” (635mm)
power: 100x, with Nagler 31mm and CLS filter.
Drawing with Paintshop Pro 7.

The Iris Nebula

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.

A Delta Winged Aircraft

NGC 1999 - A reflection nebula in Orion — NGC 1999 – A reflection nebula in Orion

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.

Much more details can be found at www.deepsky-drawings.com
