I and perhaps others would enjoy reading about your approach to NB imaging and processing. 

 

How much data do you typically like to gather for NB?

 

Do you have some favorite processing techniques?  

 

Have any filters made a real difference for you?

1. 5 hours per filter minimum for me

2. Use color masks and curves adjustments, convolution then Ha stack masked and added to the image via LRGB Combination

3. Started with the ZWO SHO filter set and they preformed well but saw a slight improvement going to Astronomiks set.

As much as I can, or until I'm sick of targeting the same area of the sky...

 

Do you have some favorite processing techniques?

 

For HOO images, once I've gotten to a non-linear state and am working curves, a trick I use is to invert the image and run a subtle SCNR on blue, then invert back. Assuming you use PI, try it and see what it does :)

I am exceptionally happy with my Chroma 3nm filters. I had previously owned Antlia 3nm filters, which I felt punched above their class. My only issue with them was a lack of QC. The LRGB filters I received had some issue with the silicon ring being out of place - causing it to intrude in the light path. The SHO filters did not suffer that issue.
