Description

Another Test image for my new 12" Dobson Telescope :

M57 Ring Nebula and IC1296 galaxy (14.8 mag, 220 million lightyears distance, barely visible)

I guess here I am at the edge of what one can do with a 12", 1500mm f/5 Dobson

(for info: tracking was quite ok, I discarded ca. 50% of all captures, either because of seeing or tracking artefacts. (out of 67 total ))

A) full scene image (50% reduced resolution)

B, final ) closeup, max resolution

Overall I am very pleased with the results.( i.m.a.o.)

Even more estonishing, by direct eye viewing at the ocular, the M57 Ring colors are fully visible!
