Ever have one of those nights where polar alignment just took forever. Maybe you ASIAir just refused to plate solve. I have had plenty of those nights. Mainly because I do a lot of imaging and I run two rigs.
With all of that time under my belt though I have learned a few things about the routine. Plate solving is probably the largest point of hangup that delays the process. I put this video together to help others out and get polar alignment done faster. After all we would much rather be imaging than polar aligning right?
There are four things in here I show to helps speed up plate solving or fix issues with it. I actually did not cover bining or exposure time simply because everyone else has already covered it. No need to repeat such info.
Keep imaging and processing!

![Noise Battle of the EM1X vs Em1 Mk3
This video is a battle between the Em1x and Em1 Mk3. These two cameras are at the top of the Olympus product portfolio. Many often call the Em1 Mk3 a miniaturized version of the Em1x, however my own experience with the camera has demonstrated that it is something more.
Now with one has more noise? Lets see the tests.
Bellow are results pulled from ASTAP. If you want to try this software for yourself it is free. Here is a link to get you started. http://www.hnsky.org/astap.htm
EM1X 240s
x̄ : 238.13 (sigma-clip iterations=5)
x̃ : 239
Mo : 236
σ : 12.66 (sigma-clip iterations=5)
σ_2: 10.97
mad: 9
m : 132
M : 4095 (169 x)
≥64E3 : 0
Vignetting [Mo corners/Mo]: -6%
Bit depth data: 12
EM1 Mk3 240s
x̄ : 220.34 (sigma-clip iterations=5)
x̃ : 222
Mo : 220
σ : 12.96 (sigma-clip iterations=5)
σ_2: 11.91
mad: 10
m : 125
M : 4095 (210 x)
≥64E3 : 0
Vignetting [Mo corners/Mo]: -4%
Bit depth data: 12
Legend:
x̄ = mean background | x̃ = median background | Mo = mode or most common pixel value or peak histogram, so the best estimate for the background mean value | σ = standard deviation background using mean and sigma clipping| σ_2 = standard deviation background using values below Mo only | mad = median absolute deviation | m = minimum value image | M = maximum value image | ≥64E3 = number of values equal or above 64000
