Hi everyone,

I finally got around to getting my pier installed and plan to do my first mega-data image this week (>16 hours) Widefield of NGC6188 + NGC6164. I need advice about the following two topics (Image Capturing + Hardware):

1. Get mega data in Ha and use it as L, with OIII & S2 binned 2x2 for colour only. This is my normal routine and find it works very well.
2. Go for a true Hubble Palette image i.e. Use SHO as RGB directly. Never done this before.

I am leaning towards 1) as it will give me oodles of Luminance data in that channel that will be rich with data, rather than spending 6 hours on each channel.

1. Use 80ED with Flattener. This gives a very well-corrected image but only @ f/7.5 d)
   
2. Use 120ED with my 0.67x reducer @ f/5. Edge performance isnt very good (though tolerable) but gives me a full stop extra of light.

I am leaning towards 2) as an extra full stop of light (i.e. double the amount) over 16 hours. I've shot an image with the 0.67x reducer (see here) and dont think I will have too many issues processing the coma out in Startools.


Thanks for reading, and what would you recommend? I have a poll to make it easier
