Reprocess of Dumbbell

[michael.h.f.wilkinson]

Tried tweaking curves in my recent Dumbbell Nebula shot. Again, I feel it depends on the monitor I use which is better. This is the original, which looks fine on my laptop, but a bit washed out on some other monitors

This is the new version, which looks fine on my other main monitor, but perhaps overstretched on my laptop

Seconds looks better on my screen, little bit brighter and more Ha showing.

Yes, the second image is better. It has the nebula pop.

As an extra experiment, I combined the stacks obtained with the 6" F/5 Schmidt-Newton (762 mm focal length) with 6660 seconds worth of data from the 80 mm F/6 (480mm focal length) obtained earlier. APP has no problem stacking two previous stacks, and in the combined data some of the outer shell structure is coming out.

As ever, it needs more data, but I will give it another go with the Meade SN6

Excellent, just starting to see the outer fans.
