Thanks Greg. We've had a run of very dark, transparent skies here the last few days. I reckon I've dropped a bortle number or 2!
But the deepest I've seen it Rick Stevenson's. His image has inspired me to image the OIII halo long before I got a dedicated astro cam. I just couldn't get much of it with DSLR.
This is a link to Rick's image of 6164, my inspiration. https://astrob.in/254123/0/ |
Yeh but, no but, yeah but, no but - his is 74 hours! Arrhhh. That's a few months worth of imaging time considering clouds, work and moon!
I think also what it shows is the superior QE of these cameras to their still wonderful CCD cousins, especially in narrowband.
The CCD I have used that is closest in performance is the Sony 694 CCD.
