What equipment did you use? I'm trying to get a sense of what I can expect to capture with my gear. Of course being in Virginia, even when I go to the cabin at the lake or shoot from the Skyline Drive cannot make up for dry clear skies. Just got the Optolong L Extreme last week. Hoping it will help. But even with good seeing and equipment, I have a long way to go on the learning curve.
I'm on the "beginner" end of the spectrum when it comes to deep space photography gear: I use a D750 attached to a William Optics Z61 on a Skyguider Pro and recently added a small guide scope to the mix. The mount is the weakest link in my setup at this point especially with the weight of the guide scope added. I've been able to get up to 3 minute exposures with everything dialed in as well as possible but that's really pushing it. With that said this image was only around 90 min of total exposure time, so I know I should be able to pull in a lot more on detail on targets once I gain some more patience and it warms up a bit (I live at 8,200' elevation).
I live in what I would call at Bortle 4/5 zone so while not a super dark site by any means I definitely have an advantage over living directly in a large metroplex (I'm 20-30 miles from Denver). I use an the L-pro for galaxies/reflection Nebula and the L-enhance for emission Nebula like this one. (With that said galaxies are quite a stretch with my small scope and I haven't tried any yet with the guiding setup) Of course the L-extreme filter came out a month or so after I bought my L-enhance. lol. I'm curious to see what you come away with using it. From my research it seems filters like these are a almost a requirement if you aren't in a dark area, but using a requires longer exposures as well so the mount and your max exposure time will be even more critical.
