252P Linear for 20-March-2016.
Wonderful clear morning!
My first unaided eye observation at 04.40 ACDT, showing slight blue tinge through the finder and can trace out just over 1 degree of coma.
The image is taken with a 75 to 300 zoom at 205 F/5.6.
In the image the coma traces out to 1.9 degree's! hard to believe a week ago this was the same view at 800mm tracing out 27 arc minutes....
Still to come 8" F/4 800mm image and animation.


Cheers,

Justin.
