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.
