M101 - Pinwheel Galaxy - Widefield

[StuartJPP]

I wanted to crop this image to just M101, but there are so many images out there with more detail than I can produce so I preferred to keep it wider. This is basically uncropped (except for stacking artefacts) from the full frame sensor of the 5D3 at 500mm. There are quite a few galaxies scattered about in the field, with the dwarf galaxy NGC5477 to the right.

Conditions weren't that good with lots of moisture in the air and a bit breezy. I have been testing out a new mount but stuck with the trusty AstroTrac for this one...feels like ages since I was out there properly.

Best viewed full size which can be done by clicking the image...Thanks for looking.

What an extremely sharp image? As usual the level of detail is incredible.

I dont normally like images of this galaxy, It always looks washed out, non defined. Seeing it at this scale looks great - brilliant image

Beautiful. Great FOV.

It looks like a twist in the fabric of the firmament - (perhaps the festivities are taking their toll on me).

Nice to see the widefield shot with all the additional items, nice and sharp too.

Thanks for the comments everyone, here's a slightly larger version which is about a 75% crop. Needs a lot more data but still pleased with the result so far.

The wide context is great. I must shoot a wider field at some time for my long FL image. This is an inspiration to do so.
