[APML] New Images Posted

Here's three from the previous new moon period.  All are single
exposures using the Pentax 67 and TMB 152 at f/7.9 on E200, pushed one
stop.  While 60 minutes at f/7.9 with a one stop push seems to be about
optimal when shooting Provia 400F from a dark site, I think I should
have gone longer with the E200 for the nebulosity shots, perhaps 80 or
90 minutes with a one stop push.  All the images are cropped slightly to
remove some vignetting from the FF/camera mount.  As always, comments
and suggestions are welcome.

This one, I think is the best of the lot.  I was happy that I could get
some distinction between the stars in the cluster apart from the dense
cloud in the background.  Registar counts 144,848 stars in this one!

This is the best I've done on this subject, and I like the way E200
recorded the different shades of red in the bright central region of the
nebula.

I'm still tinkering some with this one.  The original slide shows the
"pillars of creation" area" very distinctly, but when it's brightened up
to show the fainter nebulosity, everything is all washed out in the
core.  I tried a mask of the central area, but I haven't been able to
blend it in very well as of yet.  I'm thinking that a longer exposure,
stacking, and the mask technique are probably needed here.  As it
stands, I think the shot looks a little too stretched.

These images mark the one-year anniversary of shooting the TMB 152, and
I must say that the scope's resolution, constrast, and tight stars are
still better than what I can do with the processing part of the job.
That's a good sign, I think, for a lot of future enjoyment with this
instrument.
