galaxies and a cluster

One clear night in April. Very much a greed rather than perfection session  due to the first decent night all month but with poor seeing. You can tell when it's poor seeing. You go to setup focus and the star is bouncing around so much, you can't make out the spikes on the bat-mask. Ah well.

In order of imaging...
galaxies ngc3718 above ngc3729 in ursa major
700d on nt150s    36x5min @ ISO800

galaxy m104 el sombrero in virgo
700d on nt150s    9x5min @ ISO800

globula cluster m4 in scorpio
700d on nt150s    16x5min @ ISO800

reprocessed a year later...

...and with StarTools' latest SVDeconvolution.
