Description

A collection of 3 bright nebula in Auriga: IC 410 (Tadpoles), IC 417 (The Spider) and NGC 1931 (The Fly).

The standoff between IC 410 and IC 417 was the main focus of my composition, though I decided to include NGC 1931 for fun. The frame is also filled with faint hydrogen tendrils, which was quite challenging to process.

Original = straight HOO combination after linear fit of OIII to Ha

Rev. B and Rev. C = tone mapped versions
