Live Stacking with Starlight Live
This EAA observing session was done in the field - at
Black Forest Star Party in Cherry Springs State Park, PA. I used C14 and Ultrastar
- C14 was controlled via WiFi by Sky Safari on an iPad, images were received
on a laptop inside my trailer connected by a long active USB cable. After
some trials with FIT files from previous sessions I settled on the default settings color balance,
and used 2x boost for color saturation. The night of September 26 was
extremely clear and steady.
NGC7331, Deer Lick group, 35x8s. 18x8s sum plus 17x8s averaging. Lots
of galaxies and good detail. EAA is quite good in bringing the details in
Stephan's Quintet, 25x8s. 18x8s sum plus 7x8s averaging. Good detail
again, and in only 3 min 20 sec.
NGC7217, 22x8s. 18x8s sum plus 4x8s averaging.
Iris Nebula, 38x8s. 18x8s sum plus 20x8s averaging. Good detail, color
still off - probably need more exposure to get better color.
Pegasus I galaxy cluster, image 1, 32x8s. 18x8s sum plus 14x8s
averaging. This is one of the objects that definitively look better with
Pegasus I galaxy cluster, image 2, 26x8s. 18x8s sum plus 8x8s
NGC253, 27x8s. 18x8s sum plus 9x8s averaging
Hickson 93 galaxy cluster, 34x8s. 18x8s sum plus 16x8s averaging.
M77, 15x8s. Core is too bright, but outer rings is visible. I should
probably go for less exposure and more averaging.
Flame Nebula, 11x8s.
Horsehead Nebula, 37x8s. 18x8s sum plus 19x8s averaging. Beautiful
Running Man nebula, NGC1975, 28x8s. 18x8s sum plus 10x8s averaging
M42, Orion Nebula, 3x5s average. M42 is extremely large dynamic range
object, very easy to get the center burned out.
