Two versions of NGC 1769 and friends at NW edge of LMC. A punchier version (http://www.mikeberthonjones.smugmug.com/Category/Star-Forming-Regions/i-nBscMf4/0/X3/NGC%201769%20LMC%20Ha%203hrs%20OIII %202hrs%20Punchy-X3.jpg) has wavelet sharpening and stronger blues. A less processed version version (http://www.mikeberthonjones.smugmug.com/Category/Star-Forming-Regions/i-cQqvwG5/0/X3/0076%20NGC%201769%20LMC%20Ha%203hrs %20OIII%202hrs-X3.jpg) is shown for comparison. Which do you prefer?
[Bassnut (Fred) showed this area recently, but far more processed than either of these].
The rich young cluster just toward 5pm of centre has carved out a jewelled Aladin's Cave for itself. There is an intriguing "winged bubble" that Fred named Thor's Other Helmet about 70% of the way toward 3 o'clock.
Yellow: H-alpha (3 x 1hr subs). Blue: OIII (2x1hr subs). Aspen CG16M on 20" PlaneWave. As usual scope control, acquisition, image processing done using our own software.
(This is our first serious bit of photography since we ran into difficulties with a wobbly focuser draw tube, so we were keen to post it, as proof we were alive. Best, Mike n Trish)>
