IanL

Imager: Sky-Watcher Evostar 80ED DS-Pro, Sky-Watcher 0.85x Focal Reducer, Canon EOS 500D (Unmodified), Hutech IDAS LPS P2 2", APT - Astro Photography Tool

Guider: Orion ST80, QHY 5, PHD 2

Mount: Sky-Watcher NEQ6, AstroTortilla, EQMod

Processing: PixInsight 1.8

Dates: Friday 31st October, 2014

LIghts: 61 x 300seconds ISO400 (~5.1 hours)

Darks: 109

Flats: 100

Bias: 330 (Processed Using PixInsight SuperBias module).

I tried three different integrations in PixInsight - normal, Bayer Drizzle (1x with 1.0 drop size) and Drizzle 2x with 0.9 drop size. The Bayer drizzle did a better job on the colour as you'd expect - less bleeding of colour in/out of stars, but resolution and overall quality doesn't seem much better than standard integration. This version presented above uses the standard drizzle to produce a 2x larger image with much better resoluton. There is a noticeable difference in the size of small stars, roundness of larger stars and many more tiny stars in the galaxy arms. Even when downsampled for presentation (5x in this case) the image is much superior.
