MadMan's Astrophotography Site

the intent of testing a variety of setups for solar, DSO and wide-field astrophotography, I headed to this very dark location that I have been to 3 other times - but never in February. While I
thought I was prepared, 25 degree temperatures combined with gusts of 25+ mph wind eventually turned my cozy little field lab into a scene from the wizard of oz. Rain and clouds the
situation for even PHD and Lodestar to manage and having to image in the open and "sleep" in a running truck. Despite being equipped with some of the better duck hunting attire
one can find, using a computer in an open Georgia field in 20 degree temperatures with no indoor 'respite' for 4 days resulting in minor frostbite and real exhaustion. I did not want to
leave my equipment to the elements or wildlife and go to any one of a number of relatives houses some miles away - and I paid for it .

The 3rd and final night, however, provided the most amazing sky I have ever seen - even in the desert or at altitude. Greg and I stuck it out and tried to collect some of the data and turn it
into something useful. Hopefully that works out - but the wind and a possible bad polar align combined to make guiding very difficult.

Also, just before the trip I purchased and ended up testing the Vixen Polarie portable mount head in a variety of modes with promising results. Below are two of the 'Star Scape' single
frame captures I liked the most. They will lead what will be, I hope, decent results to be posted here from the rest of the trip.

FINAL RESULTS = Other than for the pics below - a WASHOUT. Due to wind and a crap polar align that should have been checked twice if it wasn't too cold to stay out with the mount.

"The Wizard and his Dog". That's what 3 nights with little sleep and staring at
the same landscape in a dark, cold field will make you name two trees.

Above: Tests using the Vixen Polarie portable guide head on a simple tripod with
a ball tilted to align with Polaris through a small peephole in the Polarie. Single
(albeit cleaned up) 20 second exposure in 'Star Scape' mode. Canon EOS 5D, 800
iso, f5.6, 24mm focal length.

Above: Imaging with the scopes back to an almost full moon. with
a SXVR-H18 mono camera and filterwheel. Side-by-side had been
mounted with an SXVR-M25C and a Canon EOS 24-105mm
zoom - but was removed prior to photo. Canon EOS 5D, 800 iso,
f5.6, 24mm focal length.

We thought you said "STEER

He would not leave us alone. I
named him Hub-Bull.

Narrow Band Imaging:
Wide-field Bubble Nebula, Tadpole Nebula, Crab Nebula - Hubble Palettes
processing very difficult and hurting quality. Too cold to re-check it I guess.

Planetary and Solar Imaging:

PGR Grasshopper and Flea3 Camera. Best 20% of 4000 frames @ 120 fps.
Solar - Lunt double and triple stack 80mm, Planetary - Celestron C11 Edge HD @ 2x Barlow, Satellite - Tak 106@prime with Flea3 (overexposed).
Baader filters, CGEM mount, Color Lodestar/PHD guide.

ISS - Manual capture (negative)

LRGB & Ha Imaging:

LRGB with Ha Luminence and/or HaRGB Imaging.
SXVR-H18 Camera, Tak 106 EDXiii @ Prime, Astrodon filters, G-11 mount, Lodestar/PHD guide. Note that between 25 mph wind and a poor polar
alignment these images are not of the best quality.

Simultaneous Wide-Field Imaging:

SBS with the M25C and a Canon EOS 24-105mm zoom @ 75mm and f4.0.
SXVR-M25C Camera, Tak 106 EDXiii @ Prime, IDAS-LP filter, G-11 mount, Lodestar/PHD guide. These images were taken at the same time in a
side-by-side setup on the G-11 mount as the main H18 camera images were taken.
