Looking for Ha Data / Tips/ Collaboration (M81&M82)

Hi People 

I am experimenting with adding Ha data to my OSC images, for example with continuum subtraction and other techniques. I would like to experiment with my latest image, but due to limited sky time I only captured RGB data (here the actual FOV):

These are 8 hours of 3 minute exposures with an astromodified Sony a7s and 200mm F/5 Newtonian (@ISO 2000). 
I hope to add 8 more hours tonight as it won't be clear for the days coming.

If anyone has any Ha data I could use for this image, that would be great. Of course you can decide if I can post the final image with your data here on Astrobin and your decision will be respected, any use of your data would be properly credited / posted as a collaboration. 

If you have any tips for adding Ha data to galaxies, this would also be very welcome.

Thanks in advance and clear skies,

Max

Hi,

I have some 23 hours of Ha of this region with an FOV that would suit yours and have used it in this photo:


M81 Group and IFN


If you're interested, please send me a pm. In terms of adding Ha data, the continuous subtraction technique is good but lately I have been preferring the one described in this video: https://www.youtube.com/watch?v=jJFUZY5p6yQ - I think it works quite well for galaxies.

Cheers,
André

How should I combine Ha with LRGB?
I've taken some images of M81 and M82 in HALRGB and ended up with the image below. Clearly I've overemphasized the Ha element and I've probably oversaturated the image as a whole. How do people combine HaLRGB? M81 and M82 - Early posting ...
