Hi All,
I was quite excited to finally capture this one--was a little afraid my image scale at f/3 on an LX90 would be too small. But it showed up fine. This has been cropped quite a bit to avoid all the coma from my 3.3 focal reducer. This shot actually involved the least processing I've ever used--trying to sharpen the Luminance even a bit just made it too harsh. HaRGB 80:12:12:13 (then I lost my race with the trees!) all :30 subs, colors binned 2X2. MX716, acquired and processed in AstroArt 3.
As always, any hints to improve are more than welcome. Frankly, they're necessary! (Still aiming to imitate the amazing work consistently posted on this group.)
Thanks for looking,
Larry Durst

Very nice Larry. Focus looks good and the detail of the filaments is excellent. Nicely done.

You got some great detail, it's a fine image. Looks like your guiding may have been a tad off because some of the stars aren't quite round. There's also a small off-center gradient that's stealing some contrast. Can't argue with the results, though; a lot better than my current best on this object.

Nice shot. Why did you use a focal reducer? To help flatten the field?
