Orion Nebula

We have had lovely clear sky for the last two nights. I stepped in to the garden on Tuesday and took a series of astro images. I took some images of Orion which was perfectly positioned. Wednesday morning I discovered that the wide view images were great but the zoomed in image of the Orion Nebula was completely out of focus. I completely forgot to re-focus after zooming in. So Wednesday night I tried again. This time I got a result I'm pleased with. I still need to learn how to process these properly but comparing to images on the web it look pretty much the same.

Orion Nebula A7Riii 100-400GM. Stack of 7 images at 6s each exposure ISO 640 pushed 2 stops

Here is the Nebula cropped in

Orion Nebula crop - don't you just love the A7R for this...

Images shot on my home made type 4 barn door.

I have a bit of green showing up in there which is not right so I'll have another go at processing.
