Arp 84 with my refractor

[FranckiM06]

Hello every body,
Yesterday I have shot these nice and small galaxies but it is not good result about the signal! There is 18 x 600s:

Thank you

Nice image Franck. Focal length is the key to these little galaxies.

Nice shot Franck:)

Like Doug said, grab a powermate, bump up that focal length and you'll be really cooking with gas:):)

Thank you Doug & Carl,
Yes, but I'm not sure to get good result if I would use the Powermate x4 because I should get Powermate x2 and I'm afraid to be too zoomed with x4 !!! Also, I should take some image of 15mn and more image because it will be much dark !

F30 on such a small target might not be too much, but it would make it pretty dim, and given Arp84 isn't all that bright to begin with, it'd most likely wash out. A x2 powermate would give you F15, which would be plenty on this object. Your tracking would have to be spot on as well, and at F15 would be rather onerous. Best leave the ultra long focal lengths for planetary viewing and imaging.

I thing that I will buy the Powermate x2 and I could try it !
