Superb shot. The highres is very well processed.

Wow, still marveling at this one Lee! Really good demo of the advantages of the cam. Great colours

You know, wearing fluoro pink hats and My Little Pony shirts is kind of weird Rick.

Lee, nice shot. I am NOT an M83 fan (no offence and NOT your image, just not liking the GX itself much for some reason), but you have captured it very nicely.

It would be awesome to add more data and thus give a bit more contrast to those tiny smudges and fuzzies. Cannot see anything wrong with flattener spacing either.

Thanks very much Suavi! I think I've got about 10% curvature at the edges of the frame, so it's not terrible and I happily use the whole frame when the target warrants it, I just reference the center 1000px when analysing FWHM.

So far I've managed to get no additional data on this and I'm starting to get a mild itch for new targets... we'll see

Thanks very much Mike and/or Trish! :-)

If it were mine though I'd tone down the HII regions a little bit.

Thanks Marc :-) Fair call, I think I pushed the whole thing pretty hard in terms of saturation to be honest, the HII regions did cop it.

Were you refocusing for blue?

Thanks Dunk! :-) I was not refocusing for blue. I did some tests a while ago and found that LRGB were all well within the critical focus zone of each other. I don't recall the discrepancy in FWHM being so bad between blue and the others though... it's a bit odd, not sure what to make of it at the moment.

Cheers

Thanks Rob! Welcome to the neighborhood :-) Which ZWO are you going with, and is it for planetary or deep sky?

haha. All good, I hear you Lewis. To be honest I'm pretty sick of looking at it. It was the first galaxy I photographed, and by far the one I've imaged the most. I was hoping this year to do it well enough that I won't feel compelled to re-do it next year.

If the blue channel is bloated compared to the others, either the seeing coincidentally deteriorated during the blue frames or it's out of focus. Blue being shorter wavelength than green and red implies that under the same conditions you should get sharper blue than red and green...assuming of course, each channel is perfectly focused.

[Retrograde (Pete)]

That's just lovely Lee. Personally I like the saturation as it is and the detail you've captured with a scope of relatively modest aperture is quite amazing!
