South Polar Region now STACKED and enlarged, from January 2, 2009
LCROSS Mission Exercise for Mapping.
(Coverage similar to Ashcroft’s fine, recent stack taken ~2 days
later.)
Sorry this is a large (2MB) file, for 16 bit depth (for shadow
detail).
File name of posted image : CKitting_200901020128Stack.tif
Name of observer : Christopher Kitting
Email address of observer :

Aperture of telescope : 130mm
Focal length of telescope : 1000mm if at prime focus.
(Tak triplet 0rtho Apo refractor) 2000mm here.
Type of camera used : Meade DSI iii Pro (black and white)
Camera detector dimensions 10.2mm x 8.3mm
Astronomik Infra Red blocking filter.
Image capture software: “Nebulosity” 1.8 on Mac.
50% crop in each dimension.
Exposure information : 0.5 fps, 0.029 second (~1/30 s) at medium
gain.
2x ED Barlow imaging at 2000mm focal length, f/15.
Sharpest 22 frames (of ~100) stacked via “Nebulosity” software.
then resampled 2x via bicubic (yielding 0.35 arcsec per pixel)
Mild Smart Sharpening with Photoshop.
Time and date of exposure : 01:27- 01:28 UT, on January 2, 2009
(UT).
(2.5 hr before Mauna Kea etc. was to begin imaging this.)
Observatory location: Hayward Hills, CA ,
East of San Francisco Bay.
37° 38' 48.4" N Latitude
122° 02' 09.4" W Longitude
Elevation: 180 m above sea level. Good atmospheric stability.
South polar region, with isolated sunlit peaks,
all much sharper (in this targeted area for registering stack) than
my previous, single frame.
But sharp ~single frames may be necessary for detecting any changes in
the plume?
