Hey, thanks for responding. Yes, I'm thinking maybe my system can't handle it, but it should at least let me know if that is the reason. It is a HP laptop, Intel i7-6500U CPU, 16 gb RAM, windows 10, with two graphics card: Intel HD Graphics 520 and AMD Radeon R7 M340. I have about 10 gbs free space on my SSD HDD. Maybe that is not enough, i try that out. I think it took about 3-4-5 mins to do the merge. Yes, I did apply lens correction. 3 rows in total. Now i'm experimenting with superresolution. I have 15mm lens which with I can cover the area that I want, but as I need more than 24 mp, this might work out.
