Hi all,
firstly i have modded my 1000d - the lpf2 filter removal (no replacement).
I also have a uhc clip filter fitted. With this setup i am able to achieve normal focus without problem - I can achieve focus with the APT focus tool and back out before the lens hits the "stop" so no poblem there ( i think).
However when I take some test shots the stars look pretty terrible - which is particularly evident when an imaging session is stacked and the image separated into RGB mages.
The red chanel is rubbish whilst the green and blue are not bad (roughly stretched images for examples)
this was taken with the modded 1000d and a super takumar 200mm f4 lens.
I guess my question is what can i do to deal with this issue?
Thanks!
Adam
