here is one more from the Microline ML8300 and the Pentax 6x7 400mm f/4
ED(IF) lens
I was planning to take a full set of sulfur, hydrogen and oxygen but the
conditions deteriorated last night by the time i finished the oxygen data so
I had to give up with only Ha and O3 in the can
I managed to get 11 x 10 minutes of decent Ha shots and 10 x 10 minutes of
decent [OIII].
the seeing was not so hot and got worse but the killer was the cloud cover
that moved in just past midnight :-(
anyway here is the Rosette in Ha / [OIII]
It is sort of OK, maybe you will like it
