Hi,
I have read a recent post about the GSO RC-8" scopes
and field flatteners and people using CCDInspector to
check the flatness/ collimation of the OTA /CCD image train.
Could someone possibly please tell me if these two images
which are, pretty much, optimum resolution due to very good seeing
show any sign of field curvature or collimation defects?
EDIT: see below
Thanks in advance.
Edit: sorry , didn't realise there was a free trial...
Here is a screengrab....there are differences in the two images.
Does this mean collimation is out? Or is this a field flatness issue?
I'm not sure why there would be differences either?
