Now has 13 x 20 minute Ha sub exposures for a total of 4hrs 20mins. Plus I think my reprocessing is slightly better - let me know what you think.

Looking very good. The processing is also very good - I like the wispyness you've brought out whilst maintaining the contrast around that "hole" that appears very black.

Yes, I'm pleased with it myself. Usually the jpegs come out with the wrong brightness levels and the faint detail is washed out but this one turned out ok. The extra 80 minutes under a clearer sky helped a lot too, especially with the dark dusty detail.
Robert - Can't believe the images that you are producing lately - superb.... This one is crying out for some RGB - John
