Anyone have any ideas what is wrong here? I imaged the Squid over several nights, and spent three of those on Oiii. I stacked the data but there is very little sign of the Squid. The fits header says I used Oiii. I just pulled the camera and filter wheel off the scope, and checked that Oiii is correctly placed in position 6 of the wheel. I did several tests earlier on the EFW and the wheel always went to Oiii when chosen in SGP. To me this looks more like Sii, so I was wondering if the EFW went to position 7 instead of 6? But I am finding it hard to believe that the software/filter wheel found the wrong position 3 separate nights in a row. I'm assuming this is user error on my part, just not sure where I went wrong?
Any suggestions welcome! I also did image the squid at the same time with an NBX filter on another scope, and I can see the squid, using same gain and exposure settings (and a slower scope F4.8 versus F2.8).
Fits attached of Oiii 300s sub, QHY268M, 4nm Baader Ultra Narrow High Speed 2" filter.

Any input welcome.
