Hi all, it's been a pretty wet and wild winter here in Perth and I had some work to do on the imaging system, but it's all sorted and starting to work nicely for spring. I managed to get a few clear nights over the last weekend, so I went for some narrowband data on M16. This SHO composite is made up of about 9 hours worth of subs - I lost a few subs to dew, which I didn't think was meant to happen inside a dome.



Scope is the ASA16"f3.6, camera is the QSI683 using Astrodon 5nm NB filters. Subs were 15 minutes unguided on the DDM85XL and processing in PI. I guess NB colour is always a question of taste! I've also linked to a less cropped image on astrobin, but I'm very pleased with the detail.

While the contrast looks a little washed out to my eye, it’s a very tidy result.
Nice one :thumbsup:

Well done, Andrew! Excellent detail in all the favourite features. Very nice colour.

Could, as Peter said, be slightly more contrasty (darker darks and lighter lights) without losing anything important.

A very good Eagle. As others noted the contrast could be upped.

Thanks Mike and Trish! I'll have a bit of a play in PI and see if I can get a better stretch.

Cheers Peter, sincerely appreciate the feedback.



Thanks Marc, I might just print this one!





Thanks Mike, there's definitely a consensus emerging here :-)



Cheers Greg, as most of you have noted, and certainly compared to the original 'pillars' image from the stsci team it should be a much darker feature. I've gone a bit too far in experimenting, but I kind of like the attached result as the other extreme!

Somewhere in between would be great, Andrew :)
