Walking on the Moon

NGC281 - The Pacman Nebula


Recommended Posts

An image that I've just recently processed using data I collected over the period Dec 2014 - March 2015. It was my first Ha/O3/S2 imaging run using a FSQ85 @ f5.3 and QSI690 combo.

Based on 220min Ha, 190min O3 180min S2 and processed in PS CS3 using Annie's Actions.

Final image is heavily cropped to fix

1) my poor target alignment over multiple nights,

2) remove stars affected by poor polar alignment (since fixed) and

3) remove bright stars affected by the faulty O3 filter (halo problem, filter since replaced FOC by Baader).

CS, Andy
