Milky Way: 57 x 45 degrees from 39MP/45mm lens

here's another wide FOV shot

this one was taken using the Proline 39000M on a Pentax 45mm 6x7 format lens and with Halpha and [OIII] filters. It is processed using the Hbeta synthesis method (following nature for the reconstruction rather than a non-physical method such as the so-called Bicolor method).

this is a huge FOV about 57 x 45 degrees!

that means you need PERFECT polar alignment and I didn't have it that two evenings unfortunately

This is incredible FOV! Fantastic widefield, Richard.

I think you might have explained it to me before, but do you have
a link to the HBeta synthesis method?
