Captured with Canon EOS R10 + RF200-800 set at 800 mm (APS-C so equivalent 1280 mm).
Hand-tracked single shot, 1/400s, f/9, ISO-1600. My body was leaning on my car so this can count for "improved hand tracking".

Highest elevation was ±60° at my location, although i can not provide the exact elevation of this picture.

The image is cropped since at this exposure no star is visible.

No processing at all. Not necessary.

So I had to test it 😂 I've put a NISI +9 diopter in front of my RF200-800.

NISI 49mm --> 49-55 adapter --> 55-77 adapter --> 77-95 adapter --> RF200-800 --> APS-C.

Probably not usable in real life, image quality probably sucks because the NISI is surely not designed for such an extreme magnification.

This gives a 7.4x macro. 3 mm magnified at full width on the sensor.

Phrurotimpus Borealis, seen on my kitchen floor. Shot with Canon EOS R10 + RF-S 55-210 + NISI +9 diopter close-up lens. ISO400, f/32, 10 sec. exposure (no flash) - I was lucky she was immobile.
