M8, 11hours in 3nm Ha

Hi Guys

Part one in a mega data project. Im sick of processing artifacts, so the only way to avoid that is........better (more) data .

When the moon goes away, it will proceed (moon doesnt bother Ha, but RGB suffers).

This image is a total of 11hours, 33 off 20min exposures on an LX200R OTA at 3050mm FL f10, wobbly G11 and ST10XME, taken in Sydney with a very nearby full moon.

Minimal processing. Some deconvolute and a bit of sharpenig.

The narrow 3nm Ha filter rendered nice small stars, and on referencing a few top RC (albiet lower exposure time) efforts in Lum, I recon the LX200R cuts it.

Mega data sure helps in reducing noise, its the cheap scopes secret weapon to achieving image nirvana .
