3264 / 2064 = 1.581.
Then the crop factor is 1,581.
300 mm (lens) x 1.5 (APS-C) x 1.4 (TC) x 1,581 = 996 mm FFE.
4928 x 3264 = 16 Mpixels (original)
2368 x 2064 = 4.9 Mpixels (croped)
1127 x 1000 = 1.1 Mpixel (posted in CiC)
Your original 16 Mpixels photo @ 630 mm FFE was transformed on a 4.9 Mpixels @ 996 mm FFE.
You posted your 1.1 Mpixel picture @ 996 mm FFE with only 56.9 kB and your result is very good!
Congratulations!
Antonio.
