Description

The Fornax cluster of galaxies spans about 5 degrees of the sky and its distance is about 60 Million lightyears. It is dominated by three of the largest known galaxies, NGC1316 (Fornax A, 8.4mag lenticular type, the one with the shells in the halo). NGC1399 (a giant cD type) and of course NGC1365, the famous prototype barred spiral. On the 135mm field you also see NGC1291, a big SB spiral with the outer arms wound in a ring structure.

Presented here are two pictures with Canon Eos6d, one with 300mm f/4 lens and the other with a 135mm f/2. Leading is a crop on the cluster's center, and full fields in 67% resolution. Annotated versions containing the major NGC objects named are provided, and to show the sheer masses of galaxies there is a 100% and enhanced version with just the markings for the objects of the extragalactic PGC database. PGC names would render the pic totally covered by numbers. To see the marks you need to open the full res version.

The pictures were taken simultaneously by 2 cameras on the same mount, dithered by MGEN autoguider, so the total exposure time is about 95min for each picture.

North is left.

For me, its always fascinating being able to have an outlook into the vastness of space, and see all those tiny star islands getting lost in the distant. Also, its nice to get the impression and go with your own picture as a guide to visit them visually in a big dobsonian - how far can one go?
