Its the M63 galaxy again, however with more data this time.
Several years ago when I dreamed of an EdgeHD scope I followed several users on Astrobin who had such scopes in order to see the results that they are getting. One of those users was
@Almos Balasi .
This year I saw that he had acquired 14 hours on M63. The Sunflower was a target for me as well during April when I managed to get 21 hours of materials. Here are the individual results:

https://www.astrobin.com/eu16ju/G/I decided to approach Almos and suggest to combine our data and see what happens. We are imaging with identical systems - scope, camera and reducer. Luckily he agreed so we exchanged our data and started to work
Below I am sharing my side of the story afterwards
I combined the data and made an analysis / comparison. I am imaging from the city of Sofia - Bortle 6/7 while Almos shared that he is imaging from a Bortle 4. I used a broadband filter - the L-Pro and Almos used the HEUIB-II which is a UV/IR-cut filter enhanced for shooting H-alpha nebulae at wave length of 656.3nm. The analysis showed that while our FWHM and Eccentricity values are comparable the data of Almos has a lot more signal - Revision F. Apart from the raw statistical data this can be seen in a simple comparison between his best 5 minute frame and my best 10 minute frame - Revision G.
Looking at the combined data I think that the result is heavily based on the data of Almos while my data had some slight contribution. However the combined data shows more details in the faint part and halo of the galaxy - Revision D. I really love the processed result and the details that the galaxy is showing. The result is way better than my individual effort.
Looking forward to future collaborations as there is potential for great results and are very useful in sharing of experience and know-how.
