Orion nebula with flame and horsehead

[Iceman120]

Hi all, 

hope everyone is getting some clear sky, went out earlier in the week and captured Orion from home but due to light pollution couldn't get much data. I tried again tonight but with a SVBONY CLS clip in filter and had completely different results. This is my first time using a filter and seem to have some strange artifacting on the brighter stars. Some advice on this would be appreciated. 

Canon 550d non modified with a Kenlock 135mm prime lens at F4 on am iOptron skyguider pro.

Without filter

121 x 30s @ ISO 400

With filter

constructive criticism always appreciated.

Thanks for looking

Rich
