Description

First attempt at M42 and surrounds. Fairly happy, although keen to resolve the 'blotchiness' that dominates the darker areas. Technique related - will try larger dithering steps.

Description: Another session with StarTools. Improved detail in the M42 nebulae and slightly reduced blotchiness (fixed pattern noise) in the dark regions.

Description: Yet another revision on the M42 wide field - this time with 2h total integration. Troubled by bad correlated noise and high sensor temperatures though (38C)! See recent forum post on this issue if interested.
