Imaging with FLT and 0.63x reducer
Last full moon, I conducted an experiment: a ccd image with FLT110
and a Meade 0.63x focal reducer (meant for SCT use):
The camera was Starlight Xpress HX916, exposure of 30 minutes with
IDAS LPS filter.
There's a slight coma just beginning to be visible all the way at the
very edges, but it's not very objectionable. It'll likely be a bigger
problem with a larger chip or a 35mm frame.
