I did 4 hours and 24 minutes. 66 x 240 seconds ISO 800. I am not glad with the result, because I did a comparison with another photo of 2013 with only 40 minutes, and I see that my seeing here is very worse after this two years.
The large photo of 2013 can be seen at:

Despite of 4 hours the nebula was very faint. To enhance it I will need to do some hours with UHC filter.
To get what you can see I needed to strech very much the signal. Since the files are larger than 200 Kb I can not publish here. Please take a look at
