Photometry of HD23642
HD23642 is an Algol type eclipsing binary located in the Pleiades cluster (M45). Using iTelescope's T24 Planewave CDK telescope, I took 10 images (5x B-Band and 5x V-Band) of 60s exposure time.
Using the photometry functionality within MaximDL it is possible to generate photometric values for the star, using a reference star of known magnitude.

Using the photometry functionality within MaximDL it is possible to generate photometric values for the star, using a reference star of known magnitude.
Using the values of the B-Band and V-Band I generated a colour-magnitude diagram for HD23642, similar to a Hertzsprung-Russell Diagram.
Using the B-V value, and some simple mathematics, its possible to calculate an effective temperature for the star.
Using the equation, I came to a value of 8282.6K. The professionally accepted value is 9200K. This is a pretty good result!
More detailed screenshots of the process can be found in the PDF below.

My data correlated very nicely with other studies conducted on HD23642, below is a paper published by a team at Keele University.

SuperNova SN2016adj
Over a number of weeks, I've been imaging the supernova SN2016adj in the galaxy Centaurus A using the 0.5m BCL T27 hosted by iTelescope in Siding Springs, Australia.
Cent A lies some 13 million light years from Earth, in the constellation of Centaurus.
Using very basic imaging (normally integration times of 300s) and beginner level photometry (using MaximDL) I've manged to start compiling a lightcurve of the supernova.

The resulting light curve was very reasonable (with some erroneous data points) the magnitude the software found compared reasonably well to the currently accepted value.
