IC 4831 & 4833 & ESO 141-G012 - galaxies

[jsmoraes]

In my Carte du Ciel these objects are classified as Unknown. Althought two of them has name in Google Earth.

I search for, and I shot them. They are:

Pavo constellation

ESO 141-G042 - size: 3.0' x 0.5' - magnitude: 14.5
IC 4833 - size: 0.5' x 0.4' - magnitude: 12.7
IC 3831 - size: 4.0' x 1.3' - manitude: 14.0

I got quite near of resolution of the images that I found in http://www.messier45.com , that you can see all three in http://jsmastronomy.30143.n7.nabble.com/IC-4831-amp-4833-amp-ESO-141-G012-td293.html

I am very very glad with the result ! :nerd:

Wow! I forgot to publish !

GSO 305 mm - Canon 350D (mod) - ISO 400 - 11 x 4 min (44 min) - Skyglow filter - Coma Corrector

This capture has less photos than the other, that has 20 x 4 min (1 h 20 mn). It seems that I got better process with this. IC 4831 has more details.
