Wow Peter,
that's impressive.
the FSQ-106 has handled the 36mm x 24mm frame easily
with no sign of aberrations in the corners.
It looks like the QHY 600 has worked well straight out of the box
with a QE above 80% for most of the light spectrum
and 75% at Ha wavelength of 656nm for your image.
My old QHY-9 is only giving 50% QE at 656nm for Ha.
Times have changed.
I look forward to some great colour images from you with this setup.
Are you going to try the QHY600 on the Alluna
or would it be oversampled with such small pixels?
cheers
Allan
