Had my longest session ever, 6hours, last night/this morning.

Started off last night on the Flaming Star then had a go at Orion's Head and finally a few subs on the Rosette.

and finally The Rosette

Nice. Sometimes B&W can be more impressive than colour, on my monitor it appears as a slight cast of yellow which makes the images slightly warmer than a dense black and white. Was that on purpose or a malfunction of my monitor?
