I would like to here about successes or failures in using an OAG'er for a C14 EdgeHD with a 0.72 reducer and OAG equipment recommendations.
I have put forth some effort to OAG my C14 with the 0.73 reducer in
place.? The OAG device is old and is minimalist.? With that in mind, I
have been able to use it a few times but it does limit my autoguiding
significantly - can't properly focus OAG sensor or rotate the OAG
field.? I would like to invest more time to improve this method for my
autoguiding setup.? I would also like to update the OAG device to one
with a pickoff rotator and a helical focuser.?? Before I spend the money
and time, I would like to get some opinions on OAG guiding with a focal
length of 2800mm to a small sensor (lodestar autoguider or qhyl5-II)
and roughly 8.5' x 6.5' fov.? Can it be done with binning2x2?
My current setup
has a 1000mm guide scope "on top" of the C14 and works very well except
when the guidescope is perpendicular to my dome shutter.? I have to move
the dome about every 10 minutes to maintain a good s/n for the guide
star.?? It would be nice to reduce the weight on the mount too.
Thanks in advance
