Orion Widefield
Hi,
Considering I need to go wide-field for a while, I picked up a low cost 75-300mm canon lens and for what its worth is surprising good. The only thing I believe needs to be looked at is fringing which is quite bad, although there was a UV blocking filter on the front of the lens it has some sort of fault that caused ghosting.
This is one image I took on the night, the fringe has been dampened a bit using a script called Defringe for GIMP.
It couldn't get rid of the star blowout but it did remove an awful lot of the dark blue fringe.
Any further advice would be good eg: filters for the lens etc.
Canon 450D 300mm, 40 x 15 seconds @ 800ISO
