The Rosette Nebula

Here is a Hydrogen-alpha narrow-band image of The Rosette Nebula:

Two hours in 20-minute subframes with E160 at f/3.3 and SXV-H9 camera,
Schueler H-a filter. Guided with MX716 on NP101, I binned 2x2 to
increase the signal, and this seems to work well with my H-a images.
The image is undersampled at 5 arc seconds per pixel but my seeing is
frankly not a lot better!

Do you think the 2x2 binned undersampling hurt? I'd have to expose
for 4 hours to achieve the same SNR binned 1x1.

Thank you for visiting my site.

Clear skies,
