Life Boat week in Lyme Regis this week, I just happened to walk along the beach when they were doing a RAF parachute drop.

This is a bit hard core. Here's some of the difficulty
1. The tracking accuracy was from visual polar alignment
2. Running at 1370mm focal length on a beginner mount near it's limit for payload
3. The resolution is at 0.88 arcsec/pix - below the dawes limit of the 4" refractor (1.44 limit).. an arcsec is 3 ten pences at a kilometer away.
4. Eight 300 second sub images, with 3362x2537 16bit resolution as sources, no darks or flats to provide correction.
5. Processing these images took an i7 with 16GB RAM (yes it used it all and some) 40 minutes just to align the 8 images (at this stage 16884x16884 64bit resolution) resulting in a 6.67 GB final image.. you're seeing a little crop here
The result is an image that provides detail far far beyond the normal you'd get from a 4" refractor! In fact this is starting to look more like a 12-20" resolution..

Some from today's road race, not had much time to process properly, have to go to NY, still need to get the knack of motion panning. 7D, non panning shots taken with 70-200mm f2.8L IS II, panning shots with 24-105mm F4L
A quick one from meeting today with a friend. By no means a final image, more current draft stage. I have very tired eyes at the moment so I'll take a fresh look at this and the rest of the set tomorrow morning and over the coming days

I don't think it's perfect but it's different and I really like it.
Have you been applying some fake blur? if so I wouldn't as the Sigma 85's bokeh looks better tbh.

it does normally but in this case it looked really bad, like a posterisation effect had been applied and it was really busy. Like I said it was just a draft, for the final image I'll find another way of dealing with the bokeh
Haha I'm just happy to be getting some half decent shots out of it - she was crazily awkward in front of the camera but by the end things were going pretty smoothly, thankfully.

Took this earlier whilst taking a stroll in the park with the missus.
