back focus for OAG
Hi guys,
Just beginning astro again. Life got in the way but got some nice unguided images of M42 on the weekend.
Was looking at guiding next and felt I wanted to try OAG. I wanted to try OAG rather than a guide scope as ultimately I would like to upgrade to a SCT which I apprently works better with OAG.
I currently have a skwatcher ED 80 with a 600mm focal length with a 55mm T2 ring attached to a canon 1100D DSLR.
I was hoping to get a ASI290mm as a guide camera, as it will double up as a planetary camera as well.
If I was to get a ASI OAG, would this increase my back focus too much for a DSLR.
Thanks in advance,
Dilshan
