Image Processing Advice

[Celestron4]

I am processing my data on the Wizard nebula in Photoshop (NGC7380) and have been using the Astronomy Tools Actions set but am struggling to get the nebula to stand out and to bring the smaller details out. It currently stands at approximately 1hr 45 mins of 300s exposures (I am aiming to get more data at some point) and I am using an astro-modified Canon EOS 600D. My main imaging telescope is a Celestron Nexstar 6 SCT with the Celestron 0.63 focal reducer attached, if this helps at all. The image below is one of my better attempts at processing the image and I have attached the original .tif file (it is in 32 bit form and comes straight from DeepSkyStacker). Is there anything I should be doing in photoshop to improve this? Would a light pollution filter help?

Yep, more data is needed - also think about adding flats to your workflow - uneven background is starting to show ...

Thanks very much for the advice. I did use flats, clearly not very good ones though.
