Widefield M101 with QHY9
« on: March 28, 2012, 11:07:37 AM »
Hi,

This was the first light of my new (to me) Epsilon 160. The Epsilon was not
perfect collimated. The night was very clear and very nice transparency, no high
clouds! However the seeing was horrible and on top of that the first half of the
night was very very windy. I have to discard 1/3 of my lights because they
looked blurred.

Despite not being able to recover any small scale detail I am very pleased with
the colors and overall outcome. I was not expecting to capture the Ha regions of
this galaxy but they are very prominent.

The other unexpected feature is a bright supernova PTF 11kly, it is the blue
star at 2 o'clock from M101 center. I measure the position and brightness an I
found the following:

Position RA: 14 03 05.73 DEC: 54 16 25.8
Brightness: 13.5

Unfortunately there are just a couple of galaxies that make a good match for the
image scale of my telescope/camera.
