Jon,
The M78 shot is stunning. Great job even if the seeing was deteriorating!
It's great to see some more film shots.

Subject: [APML] Hovenweep Adventure


As you know from my recent dark site report, I took my gear to Hovenweep
National Monument in Utah last new moon.  Here are two images from that
trip, both taken with Pentax 67 cameras and the TMB152 refractor at f/7.9.
As always, your comments and suggestions are welcome.
 
This shot was difficult to process for some reason, and may need more work.
It's the northern part of Barnard's loop, along with M78 and some of the
pervasive faint nebulosity in the region.  The reflection nebula reported by
Marco is visible in the lower right of the image.  The V-shaped nebulosity
in the upper left, which also appears to have a small reflection component
around the star at its apex, is not identified in either Sky Atlas 2000 or
Uranometria 2000.0.  Does anyone have a designation for this nebulosity?   I
think E200 did pretty good on M78, but unfortunately the seeing was going
downhill by the time I got to this target that night.  The exposure was 75
minutes, pushed one stop.

I've always wanted to shoot this pair of clusters, but it's low in the sky
and is visible at the time of year when weather can be a problem around
here.  Luckily, I caught it at a good time this year, and shot it during
some of the best seeing of the night.  This one was shot on Provia 400F,
which I think did a pretty good job on the star colors.  60 minutes, pushed
one stop.

Both images were cropped somewhat to improve the composition and to
eliminate a bit of vignetting.  The Barnard's shot is was not composed
exactly as I'd wished, so it is actually not cropped very much, and the
vignetting is fairly evident in the corners on the right side.  I'm also
still working on an E200/400F composite of IC443 that I hope to post soon.
This month I expect to meet up with APML'er Glenn Shaw at Chiricahua.
