| During a long 'weekend' from 2/10-2/13, I went on what was for me at least a very physically exerting 3 nights in a field in middle Georgia on my cousin Jay Smiths 3000 acre farm. With 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 first night provided only a 1 hour break to align and park the mounts. Wind and cold on the second day eventually led to the destruction of one of my tents, an impossible guiding 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.

| "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. Losmandy G-11 with G2 mount, Tak FSQ-106EDXiii imaging 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. |
| The setup prior to it blowing away with Greg, my equipment and me in it. |
| We thought you said "STEER PARTY", not "STAR PARTY"! |
| He would not leave us alone. I named him Hub-Bull. |
| Narrow Band Imaging: Wide-field Bubble Nebula, Tadpole Nebula, Crab Nebula - Hubble Palettes SXVR-H18 Camera, Tak 106 EDXiii @ Prime, Astrodon filters, G-11 mount, Lodestar/PHD guide. Note I had a bad polar align the entire trip making 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) with Flea 3 in Tak 106 @ prime - no barlow. Hey, it sucks but I tried for a LONG time to even get it on film through a scope! |
| NGC 2403 - HaRGB - 1 h 12 m - H18, Tak 106 @ Prime |
| Coronado 80mm 2x etalon - Grasshopper Camera (from field day at my office with Stephen Ramsden - processed by me) |
| Sun - Lunt 80mm 2x etalon - M25C Camera - from Hawkinsville |
| MORE COMING FROM THIS TRIP SLOWLY! |
| Sun - Lunt 80mm 2x etalon - Flea3 Camera |
| Venus - Tak FSQ-106EDXiii @ Prime - Flea 3 camera. Lum image taken as test for ISS attempt. |
| 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. |

| Crab Nebula centered in Taurus - M25C with IDAS-LP - 1 h 15 m |
| Antares in Scorpius - Only 25 minutes - M25C with IDAS-LP |
| M42 & IC 434 in Orion - M25C w/ IDAS-LP - 1 h 15 m - Add 1h20m Ha to the right from H18 camera |
| M101 in Ursa Major - M25C w/ IDAS-LP Filter. 1 h 15 m |
