Using a 20" f3.9 and a 27mm Panoptic + OIII filter I did get most of the
Rosette in one field and it is a sight worth seeing.The combination gives a
field of almost a degree and a power of 75x. It also fits most of M33 in
one field ( without the OIII filter of course )
I must try for Barnards loop with it. Must have missed NGC7000. Keep going
for faint PN's
