This was a big but exciting project to capture SHO data on 2 panels during summer short nights.
I used my Canon 200mm paired with the ASI1600MM under heavy LP (SQM 18.3)
Image integration was also epic with 285 O3 frames ; 207Ha and 219 SII but APP made the job easily.

Here is the standalone SHO other versions are available here :
