Can't process Rosette Nebula. Is my data bad?

[varius21]

Hello everyone,

Last night, a clear sky after a long while for me, I decided to take a few shots. I setup my rig in the garden and shot Rosette Nebula for an hour an a half... I am new to this, so don't stone me if I completely messed up.

I used a modded dslr, an L-eXtreme filter and shot 30 x 180".

I also added 20 flats in there.

Here is the stacked photo tif attached... can you tell me if I messed up stacking, if the data is bad or if I can't post process it due to inexperience?

Here's also a photo of how it looked on my asiair pro while shooting.

 

 

Many thanks in advance

Thank you for the reply and trying to check out the files, Peter.

After spending some more time and working on the tif without the flats, I managed to make this.... is that bad? What could I do to improve it?

Thank you

I’m not very experienced either but I think that’s pretty good for 90 mins exposure. What’s the DSLR and what bortle level are your skies?  For what it’s worth these are my efforts from Friday night; 27 x 300 seconds, bortle 5, QHY 8L-C:
