20240322 12P Comet

 

Less than perfect sky, captured a few short exposures, probably below 10s each, stacked together to form the above before the comet sinked below neighbour's roof.  Just a record.

Canon FD 300mm f2.8L DIY modified to fit on my Canon 70D, tracked but unguided.

New monochromatic camera arrived, much faster frame rate and slightly cleaner images.

Seeing 6/10, transparency 6/10.

Full disc at 1023 (GMT), reducer still required for full disc:

Insert 2x barlows, oversampling.

10:26 (GMT)

10:27 (GMT)

Quite delicate detail, love the quality of frames produced.

10:30 (GMT), I have confident that it should be a closed loop but the dynamic range is not enough to show the darker part, maybe I shall take another shot with longer exposure to form a HDR image?
