My first variable star measurement

Postby Dave Smith » Thu Dec 15, 2016 8:02 pm

Recently I produced an image of the variable star Algol winking. It was just a fun animation but not at all scientifically accurate. So I thought I might try some proper photometry with help from publications on the BAA website. This is one of the recommended stars for beginners. EG Cep. I found the star using SGPro and took a 30s sub every 5 minutes while it was clear which last night was for about 7 hours. Unfortunately it was just getting to the interesting bit as the cloud and mist rolled in. There was also a near full Moon which didn't help. I don't have the correct V-type photometric filter so used a green filter instead which means the magnitude values will be out. This was meant as a trial run to help me decide whether I want to pursue this further and whether to purchase the proper filters so that useful scientific measurements can be taken. I certainly found this fascinating especially as I could see the graph developing during data collection. This was done with my Megrez 90 refractor with 0.8 x FR/FF and Atik 460EX CCD camera. The photometry was carried out using MaximDL.
