Starex

Hello everybody. As soon as the weather allowed it and while working from the balcony of the house I threw myself headlong on the shot of the star HD 89884 which is located in the constellation of Hydra. This time I tried to take a star of mag 8-9 but in the portion of the sky that I find myself I found only this one which is mag. 7.13. In the rush to operate I chose to do 600 s poses but as my dear friends pointed out to me, they suggested for the next time to adopt at least 960 s due to the 2400 l / mm grating. It is always a Be star with a clear double peak of emission in Halfa. Excuse me if I have dwelt but I got quite excited with the new spectroscope which seems to work very well!
