It was a relatively warm night. I was inspired to try and capture
this by some Webb Telescope tweets and to keep learning how to use
my gear and somewhat quickly find Stephan's Quintet.
I started with my first focus picture at 6:51pm and finally started
the actual pictures for stacking at 8:49 pm. This is a little long,
an hour to focus and locate. It is harder on the fixed focal
length Red Cat than the Canon 70 to 200 mm lens.
Here is the full field view, with the resolution cut down from 6984
by 4660 to 1800 by 1201 and compressed for the web:
Now cropping down so that the Quintet as well as the galaxy seen in
the upper center right:
The galaxy is identified as Caldwell 30. The Quintet is
starting to appear below the galaxy. I cropped the original image
and then saved as a jpg as 1800 x 1201 pixels, so better resolution
on the web than the first picture.
Finally, cropping some more:
This last image was not reduced in size. The resolution the same as
the full image. There is some loss as this is a jpeg not a
tiff. I think for a rookie at Affinity, this is not too bad!!
