Well done in capturing the proms, as they are incredibly dim in my 0.5A system...I finally detected them but they need 10x more exposure than the disk itself.

Peter,
Could be down to tuning...
I use a SM60 double stacked with a PST etalon, ASI 174, probably around 0.5A bandwidth and found the proms pretty bright.
Yes, a separate longer exposure always makes it easier.

Thanks Peter I find the Quark is very good at capturing both especially the full disk but closeup when the proms are very dim I capture 2 images for proms and disk and stack them is PS as I had to do here.
