Live Stacking with Starlight Live
This time I used my Orion 10" Newtonian again, my C14 mount broke down.
It was fun session proving that f/4.5 is not bad, if one allows more
exposure time. I have a feeling I am getting better in color adjustment as
well. I have browsed through some high-profile Summer objects, it is very
captivating to observe the same objects I have seen so many times visually
with EAA. I will be spending more time with EAA! I will also try C14 at
f/8.8 on planetary nebulae and other small but relatively bright objects. In
most objects below I used sum-mean protocol, i.e. accumulating some
exposures as sum first, then adding more as average. I have used non-linear
scaling as well, it brings higher dynamic range, which is important for
globular clusters and bright nebulae.
M4. Low to the west by the time I started.
M17 the Swan. Couldn't resist to check it again.
M16 Eagle Nebula. I always struggle to see the Eagle visually, but with
EAA it is easy. I need to accumulate a bit longer exposure,
M20 the Trifid Nebula. Again, more exposure needed. The picture looked
less grainy in the dark on my laptop screen. Still I am quite pleased. With
longer exposure blue part will be much better.
M8 Lagoon Nebula.
M22. Low in Southe-West at this time. Came quit yellow, not sure it is a
color balance problem or some low haze.
M13. This is how I like my globulars. Much better than M22.
M57 Ring Nebula. IC1296 galaxy faintly shows below the Ring.
M27 Dumbbell Nebula.
M102 Spindle Galaxy. This is relatively bright object, but central dust
lane is clearly visible, hard to see visually.
NGC5907. Another edge-on galaxy.
NGC6946 Fireworks Galaxy. This one is faint, and needs a lot more
NGC6960 Veil Nebula close to 52 Cygni. More exposure needed, and a
bit of refocusing. It is easy to forget all these slews may influence focus
a bit - need to remember next time.
