Binary star measurement.

Using the time variations of the eclipses we are able to calculate the orbit of possible companion objects big enough to have an effect on the orbital period of the binary pair.

The picture below is the plot of light magnitude from the binary pair. The timing of this minima is then corrected for our orbit round the sun and further corrections to give the precise time of the eclipse.

many of these are measured to find orbital variation caused by third objects.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
A supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The distance to the nebula is not precisely known, but data supports a distance of about 1,470 light-years.

Just taken with R,G,B Filters a stack of 3 x 400sec images for each filter. Darks and Flats from the current library. Taken from Selsey with the RC Astrograph and Starlight Xpress H694 camera at -12c.

Ok
As requested the new Observation manager and Script Runner for Astroart 7.0 with all the new automation features for preprocessing and time series variable image collection and processing now available.

You will also need a temp file on the desktop for all your images and log files.
You can put this anywhere as long as you define the location in your Param2 file.

Any questions just email me at web@astro.me.uk

The sky was clear but a lot of heat rising from the ground.
3 X 300 seconds for R G B with RC Astrograph
Processed with Observation manager 9.12e using Astroart 7 script interface.

Yes, this is the result of a star measurement session. A time series of V filtered measurements of RW Tri at 880LY.
From this information you can estimate sizes of objects and rotational period.
