Please, don't judge this, it's a  very short integration to be a good narrowband image, I just did this like 3 weeks ago while I was waiting for M31. 

I got clouds for a while so I'm processing stuff I haven't done or didn't really care about. 

Also the first time test of my Asiair Plus

Actually did it twice so it's about a 2 hour image, too little time.

 

What I found, that it has plenty of both Ha and OIII to get out of it. Everyone is drawn to the Bubble nebula right next to it, but the Crab could look spectacular with plenty of time. 

 

Here is the info: 

Svbony 80ED doublet with its own reducer/flattener

ASI 533 mc pro 

120 seconds x 65 with ZWO duo narrowband filter. 

The filter created halos around the bright stars, so I removed those, by first removing the stars and clone-stamp tool out the remaining halos. 

I did a "fake" SHO image here from duo band narrowband image and if I would sit on this long enough, it would be an amazing image. 

 

Very noisy, needs another 10hrs at least, to be considered ok in my book.
