Entire vela SNR complex in narrowband colour

Hi all
Tonight I used my 50mm f1.8 lens to get the whole Vela SNR area, with Houghys cooled DSLR
Oxygen 3 image, 4x15mins ISO400, Baader narrowband O3 filter, 50mm f1.8
Ha image, 3x15 mins ISO 400 Baader 7 Nm Ha filter, same lens.
O3 image for green and blue channels, Ha for red.
had a few goes at it as didnt look all that great. Still doesnt seem to be as effective as with the 300mm lens. Also posted the Ha and O3 image on their own. The O3 image showed little nebulosity apart from the fibrous tendrils of the SNR
