Too restless to sleep so... Found some data on my hard drive of the Grus Quartet that I forgot about from September last year. I probably wanted to add to it but got clouded out.
The Grus-Quartet consists of four large spiral galaxies which are relatively close to each other. Distance is estimated to be between 55 and 70 million light years.
GSO 10" F4 Newtonian, full spectrum modified Canon 1100D, 419 x 30 seconds unguided.
