Albireo B / and how to gain 40% flux... :-)
Posted: Tue Jul 28, 2015 11:06 pm
Hello,
tonight I'm taking some spectra of Albireo B (beta Cygni B), a Be type star.
I was cautious to focus the telescope by maximizing the Halpha flux. Using 20sec exposures, it took some time but I gained around 40% flux so I think this method is worthwhile!
Otherwise, I added a flip mirror (wanted to be able to do some star watching without having to remove the eShel fiber injection unit. I posted some pictures on my blog web site.
I also added an Oregon Scientific weather station (not recognized by PRISM from what I could see - too bad). I also posted some pictures on my blog web site.
Cordialement,
Olivier Thizy
