New light curve for NSVS14256825 binary.

Not the usual view of the moon.. Taken with my phone!

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.

I have included a sample TEMP file for the ObsMGr10. This gives you the file naming conventions I have used for Master Darks and Flats:
MD30B1 for example is a 30 sec master dark binned 1X1
For the flats the names are more obvious except that after L,R,G,B I have used filter slot numbers. eg I have a Johnson V filter in slot 6.

Hope you can make sense of this.

Clearly there is a lot of system setup to do before you have full automation, but once done it makes life very easy to get say 100 variable star measurements for a time series curve. All automated and checked for accuracy and noise level.

Hope this helps.
