Fred the real problem is gradients at f/2.8 partly due to the vignetting. At f/5 this is far less severe.
I was going to collect narrow band O3 and HA and use this data to enhance the very faint nebula. The weather was not kind while Vela was high.
Here is the central panel showing the Vela SNR with added narrow band. 3.7MB

With better weather will try again next year at f/5for colour and f/3.5for NB.
