Ta Marcus...getting there. The h-alpha data is surprisingly faint. I will likely have to swap out the 5nm filter for a 3nm one for a better S/N

Is that a feature you'd accept as "in the data" or something of a processing artefact? I'm interested as that sort of thing peppers every image I work on (I guess mostly because I don't use any masks in processing), and wonder if its something I should accept or invest time in addressing.

Ta ..see above. The star likely is quite red, but it may simply be the h-alpha filter I'm using is a different spec to the OIII.

The QE if the camera is quite high. That plus a 3nm OIII shows faint structure even in tthe 5 minute subs.
Compared to my FSQ the AP130 has 60% or so more flux collection and is faster, running at f4.5...hence not too hard to harvest photons without
the heroic exposure times

Too faint for my skies though. I started on it in Oiii then gave up after one night.

Thanks for the view.

Ta Guys. My estimate is it will need about double the exposure time gained so far. RGB stars would finish it off nicely.
