I have been working on this high resolution panorama of the Milky Way for 5 months - by far my biggest astrophotography project to date. As a bonus I managed to catch Comet C/2017 K2 Panstarrs as it passed near the Blue Horsehead nebula.
It consists of 46 separate RGB image panels using my dual camera arrangement (CentralDS Canon 6D & Sigma 85mm F/1.4 and ASI294MC Pro & Sigma 40mm F/1.4) plus an addition 4 panels of Hydrogen Alpha taken with my ASI294MM Pro & 40mm - over 34 hours of integration time in total
 
Each of the 46 panels was first  integrated in two sessions in APP, then all 46 registered in APP using Mercator Projection with one of the central panes as the reference.  I had "analyse stars" set to 2000, MBB=20, LNC Level 2 5 iterations.  The many trial integration runs each took 4 hours on an overclocked AMD Ryzen 5900X / 64GB RAM / 1GB Pcie Nvme SSD / GeForce RTX2060 Super
 
The resultant FITS file was 6.2 terabytes in size with a resolution of  33748 x 15840
 
I have also included an early trial run image without blending.

Well that is absolutely fantastic! I immediately showed it to my wife. 🙂 Well done, did you use the later version of APP?

Thank you so much Vincent.  Yes I used  version 2 beta 4.   The Star reduction module crashed the software - but dont worry this file crashed or locked up at least 3 other  programs too !

@vincent-mod my panorama made Astrobin Image of the Day today 😀 

It also made the NASA APOD shortlist, getting featured on their "Sky" facebook page and attracting a lot of attention.

Good advertising for APP !
