Binary Variable EB1

Hi Alan

I have completed the course except for the Week 8 and the Final Badge Quiz which I will delay until I have revised the course from my notes. It has been fascinating, although I must confess I was familiar with the basics in the first half of the course, having passed GCSE Astronomy in 2018 and several other Open Learn astronomy courses. I have also casually studied the early editions of the 2 excellent textbooks for OU Certificate in Astronomy, namely Sun and Stars and Galaxies and Cosmology.

I have looked for my chosen binary star EB1 on Stellarium using the co-ordinates and found nothing but empty space even with the maximum magnitude value of 21. The closest bright star seems to be epsilon Per. Are these stars just too dim or not significant enough to be shown in Stellarium?

Also what is the ISO rating of the camera used on the COAST telescope and the field of view. It could only image 2 of the main stars in M45.
