I dug up some old data taken with a canon 85mm F1.8 and reprocessed it.
The data was collected unguided and using ICNR. So there was a bit of drift between exposures.
There was only five exposures per exposure set but it was enough to improve the resolution.
Canon 5DH, Canon 85mm F1.8, Hutech LPR filter, ICNR for all exposures.
Carina to Centaurus
Exposures 5x(30s, 60s and 120s) at f4, 5x(120s and 240s) at f2.8 all at 500 ISO.
