Barnard’s Merope Nebula

I have thaught it would be useful for ASOD members to have a sketch of this very little nebula, hidden in the light of Merope. It is very difficult to see, unless the seeing is very good, and it was the case.

17.5″, 3 Hours, and the Eta Carina Nebulae

Hi all,

Scope time has been very scarce this year. This sketch was done in April.

Encouraged by my attempt at Eta Carina through my 8″ dob, I trained my 17.5″ dobbie at the same target, again from Sydney.

This time, I also used my Grand Daddy of all eyepieces, a 35mm Masuyama. A bit long for this f/4.5 scope, but my only OIII filter was a 1.25″.

Eta Carina is not only huge, it is a very busy place. There are multiple shockwaves within it, masses of star formation both just initiated in the form of dark pillars, of those whose nuclear fires have just kicked in, nebulae within nebulae, and a super massive star about to go supernova.

This magnificent NASA site shows all of these details.

Again, the Homunculus Nebula is too small at 57X, but the supermassive star, Eta Carina, it is associated with is the bright reddish one.

Armed with a battery of sketching implements, the result of 3hrs is below. Ooooohhh, I am going to have soooooo much fun redoing this one at a dark sky site!

Scope: 17.5″ f/4.5 dob
Gear: 35mm Masuyama, 57X, OIII filter
Date: April 8, 2011
Location: Sydney
Media: white pastel, white & black charcoal pencils, white chinagraph, white and coloured ink on black A4 size paper

Cheers,

Heart of the Orion Nebula

Observer: Saeed Zohari
Date: Dec 29, 2010
Time: 20:40 (Tehran: +03:30 UTC)
Location: Tehran ( Lat.: 35° 43.158’N, Long.: 51° 30.616’E, Elev.: 1278m)
Optic: Telescope: Maksutov 102mm Focal Length: 1300mm
Eyepiece: 15mm 66d UltraWide
Object: Trapezium Cluster in the heart of the Orion Nebula
Object Type: Cluster and Nebula
Media: white pencil and black paper

Description:
The Trapezium, or Orion Trapezium Cluster is a tight open cluster of stars in the heart of the Orion Nebula, in the constellation of Orion. It was discovered by Galileo Galilei. On February 4, 1617 he sketched three of the stars (A, C, D), but missed the surrounding nebulosity. The fourth component (B) was identified by several observers in 1673, and several more components were discovered later, for a total of eight by 1888. Subsequently several of the stars were determined to be binaries. Telescopes of amateur astronomers from about 5 inch aperture can resolve six stars under good seeing conditions.
The Trapezium is a relatively young cluster that has formed directly out of the parent nebula. The five brightest stars are on the order of 15-30 solar masses in size. They are within a diameter of 1.5 light-years of each other and are responsible for much of the illumination of the surrounding nebula. The Trapezium may be a sub-component of the larger Orion Nebula Cluster, a grouping of about 2,000 stars within a diameter of 20 light-years.

M42
Diffuse nebula
I did this sketch in my back yard in Vernon B.C. Canada.I live in red zone light polution.
the sketch was made on Jan 9 2011 at 12:20 amPST
I pre loaded the sketching field with Graphite pencil.I made the Nebula with pencil smudged,as well as a blending stump.I have been using a felt tipped pen for my stars ,I am happy witht the results from it.I also used a kneedable erasor to remove the dark dust lane from between M42 and M43.

Tha sketch was made with an 8″ Dob with a 7mm Pentax XW 171X

Thanks
