The Orion Arm of the Milky Way panorama

I took this nightscape 2 weekends ago at my dark site. It was a gorgeous night and I saw some oddball meteorites and a tumbling bright flashing satellite.

3 panels, each panel consists of 8 images. Pixel shift feature of Sony A7r3 where the sensor shifts 1 pixel between a set of 4 images using the IBIS stabilisation system so each colour of the Bayer colour Matrix records on every single pixel instead of 1 in 4 for red and blue and 2 in 4 for green.

I like it as it gets rid of excess noise, improves resolution and deepens the colour. Plus one click gets 4 shots! I set the gap between exposures to 1/2 a second so it is faster than an intervalometer or by hand.

It does require a tracker as pixel shift doesn't handle motion well.

Thanks Marc.
I am planning to get one of my cameras modded in time for the Milky Way season to capture a lot more of that.

Cheers Rick. I take these while my CDK is doing an imaging run.

Thanks Mike. That was taken 15 metres from my front door! I'll have to travel a bit more to get some more creative locations. Its very convenient as my main imaging rig is running an image sequence so I have plenty of spare time to do these.

Fabulous image Greg.
Pixel-shift tech is very cool and it's great to see someone's utilising it in astro imaging.

Thanks Pete. Yes I think it adds a little something that I don't normally get from regular stacking.

There is a fabulous piece of 3rd party software that will scan your folder of images for the pixel shift ones, then combine them into a single image and save them where you want them. It is fast too. It takes most of the work out of handling the individual files and loading them into 2nd rate Sony software which is very slow.

Greg.
