My last work on an object very difficult: https://www.flickr.com/photos/17910585@N06/32946297833/in/album-72157662167213281/
taka tsa 102 + toa35 flattner =800mm focal lenght here you can see the integration data http://www.astrobin.com/288419/
Thanks, it is for me the more difficult object i have taken. No other images in the world on these tails (except one) . I think that this object should require a study from Nasa with its telescopes.
