I realise it will take longer to capture the data but other than that what are the technical limitations?

Hi Rene,
I use 3.5nm SHO filters with ASI183 MC Pro OSC. Mono would improve the imaging but for me OSC is the camera I have now.
Here is an example process for two targets:
* ASI183 MC , Esprit 100
* NGC 3576 5 X 300 sec Sii, Ha, Oii 3.5 nm Bin1 gain111 Temp -20C
* NGC 3372 10 X 300 sec Sii, Ha, Oii 3.5 nm Bin1 gain111 Temp -20C
* Darks, Bias, (No Flats)
Subs for each filter were individually stacked and converted to black and white, then followed the SHO integration process in Affinity using Hubble palate.
The process was easier than I thought and I think if I used a Mono camera I would get finer detail but happy with the outcome for such a short exposure time. Also the Sii signal was surprisingly strong for these targets.
