My 2c: Even though I did say your contrast was understated in my joking response, we are almost in personal taste territory here anyway. After all there are a few folks in this forum that like the "misty" look. With so much tonal range in the neb thoughout the image, the nuance of variation at the dark end will be hard to discern in anything but a darkened room on a perfect monitor if you are ruthless about levelling the histograms. So, is that what you should do? Depends on the subject matter and your taste and whether you're catering for those with "perfect" monitors. For a small galaxy in a sea of black space it makes sense (because you may not want the space to appear grey), but for a neb whose dynamic range is large across the frame it may not make sense because your eye may not perceive the tonal subtelties you want people to see at the dark end. EG: can you see the difference between the background and 1 & 2 in http://www.lagom.nl/lcd-test/black.php . Now imagine if 1 & 2 were surrounded by brighter areas, would you be able to differentiate them?
It's all debateable I know, but do get a new monitor so you can make the decision and not your monitor!

Thanks my faithful monitor monitors  I appreciate the feedback
Marcus, I have adjusted my screen so I can juust see all 20 squares on that page you linked to. So, can you both adjust the following image to look good on your monitors, please  ...and post the result for me
Gabriela
EDIT: After adjusting my screen contrast & brightness to reveal all 20 squares on the page link Marcus supplied, I have now adjusted the black point of the Gabriela close up image, to look like Phils reworked version in post No 31, and posted it seperately on my site, what do you think?
Adjusted Gabriela

The wind buffeted many of my colour frames elongating the stars, and some of my Lum (Ha OIII SII) so culling the worst frames and star rounding were necessary  ...so even though the result is ok it is mildly frustrating to know I am not displaying the full capabilities of the scope-camera combo in this result. The first night I used this system at my new place the conditions were quite good, no wind and reasonably good seeing and these images (crops) of tiny distant galaxies and galaxy clusters around NGC 253 were possible  ...no chance of this on a typical windy night here though

Yes, with a straight levels adjustment the adjusted version looks fine on my monitor Mike. I did a quick & dirty version too to demonstrate what I mean by contrast, but mine was a bit more than straight levels adjustment. Emailed it to you.

That new version looks fine Mike. Tail of the histogram about +5 from black which is about where I would have it for this kind of image. Contrast and levels in the image itself look fine to me, clearly better than the original as I flick back and forth between the two.

Thanks Marcus and Phil, very helpful guys  and thanks for the private email ice skating coach Davies, I will work harder on my figure 8's
Of course this means I really should go back and adjust all the images I have taken and processed on this monitor as they now look very bright on my monitor....
The down side now is that people with unadjusted monitors will see my images as clipped, like I did of David Fitz-H's images

We have protos of these display types at work. They are great for flight simming.

That repro looks better on my monitor. Nicer contrast and blacks.
Love the stars and detail but I am personally not a fan of this colour scheme. Too green and coffee although I like the misty blues. I like the soft light browns and blues Martin has in his narrowband colour scheme. Of course colour likes/dislikes has been beaten to death on posts so that is the usual caveat so each to their taste on colour.

Cheers guys, appreciate the feedback, even though your colour opinions are opposing
This image and this thread has given me some great inspiration for my presentation in New York in April

Thanks so much Ross, glad you liked it. As for the detail, it will improve again once I am free of wind..?..  ... THIS nicely demonstrates what this scope can do on a windless night with quite respectable seeing and is the the only completely wind free imaging session I have had from my new dark sky site (since Oct)  so protecting the OTA from wind (not mine  ) is paramount for optimal resolution.
