Started work on my first photometry project tonight which I will do with my friend GingerGeek. T Coronae Borealis, which is also known as HR 5958 in that constellation is the target. I have been working on the information provided by the BAA
and also from the AVSO

Both the above have proved useful in understanding both the situation and the comparison star/s to observe too. In my case I will attempt to image T CrB along with Epsilon CrB as this is a non variable mag 2.2 star.

Tonight I managed to take a few different subs at varying exposures, both to characterise the behaviour of the camera on this Field of View, but also to create an annotated overlay to help pinpoint T CrB on other frames.
After taking exposures ranging from 1s to 300s, the latter being for the annotation, I slewed to the Moon to take my first image through this new Sky-Watcher Esprit 150EDX.
