My Ha not working

[Taraobservatory]

Hello, 

 

 

The other night I was imaging Sh2-240 and I just cant see any detail. Even in 5min subs under bottle 2 skies. Has anyone experienced this before? 

I use these coordinates (see image)

Here is my equipment is QHY260M with Chroma 3nm filters and an Esprit 80ED 

Here is a screenshot of the image. What's going on here? Is my filter not working? Is it the orientation? 

In need of some assistance

I don't know if this is your problem but I imaged this with a F4.3 scope and racked up 5 hours of 3 min subs with a OSC camera and I could hardly see it, it needs a lot of time I believe.

I think this is a target needs a very large number of integrations.  I cannot imagine anything would be visible on a 5 minute Ha sub.  I have seen what are described on SGL as “short” attempts at this target run to 13 hours or more and longer attempts range up to 26 hours or more.  I think it is a target that benefits from as much integration time as possible 🙂
